The Siemens 5SV3344-6RC is a SENTRON 5SV3 Residual Current Operated Circuit Breaker (RCCB) designed for residual-current protection in suitable three-phase AC electrical installations with neutral. It is a 4-pole / 3+N, Type A RCCB with a 40 A rated current and 30 mA rated residual operating current. Siemens identifies the corresponding 5SV3344-6 as an instantaneous 4-pole Type A RCCB, rated 40 A, 30 mA and 400 V AC.
The India-facing designation specifies 415 V and 4MW, making this model suitable for compatible three-phase-plus-neutral distribution boards, industrial panels, feeder circuits and residual-current protection applications.
The 5SV3344-6RC belongs to the Siemens SENTRON 5SV3 RCCB family. Its primary function is to detect residual current and disconnect the protected circuit when the residual-current level reaches the specified operating threshold.
The 4-pole / 3+N configuration makes it suitable for three-phase electrical systems with neutral. Siemens' current Industry Mall identifies the corresponding article as an active 5SV3 Type A RCCB, 4-pole, 40 A, 30 mA, 400 V AC.
The RCCB has a rated current of 40 A.
This makes it suitable for compatible three-phase distribution circuits and feeders where a 40 A residual-current protection device is required.
The protected circuit should always be designed so that the RCCB operates within its specified electrical ratings and installation conditions.
The 5SV3344-6RC has a rated residual operating current of 30 mA.
When residual current reaches the specified operating threshold, the RCCB trips and disconnects the protected circuit. Siemens' current datasheet confirms 30 mA as the rated tripping fault current.
The 30 mA sensitivity should be selected according to the complete electrical protection design and applicable installation requirements.
The device is a Type A RCCB.
Type A residual-current protection is designed for residual currents containing AC components and pulsating DC components. This makes Type A devices suitable for many modern electrical installations containing electronic equipment and rectifier-based loads.
Potential applications can include:
Electronic power supplies
Rectifier-based equipment
Variable-speed equipment
Automation systems
Industrial electronic machinery
Modern commercial electrical equipment
The correct RCCB type should always be selected according to the residual-current characteristics of the connected equipment.
The 5SV3344-6RC has 4 poles, suitable for three-phase plus neutral circuits.
This arrangement allows the three phase conductors and neutral to be incorporated into the residual-current protection system.
Typical applications include:
Three-phase distribution boards
PCC panels
MCC panels
Industrial feeder circuits
Commercial electrical panels
Sub-distribution boards
Machine supply circuits
Factory electrical systems
The supplied India product designation identifies this RCCB for 415 V AC applications.
Siemens' current technical data for the corresponding 5SV3344-6 specifies 400 V AC as the rated AC supply voltage.
For the SB Smart product page, the 415 V India-market designation can be retained, while actual installation selection should be checked against the Siemens technical rating and the electrical system design.
The 5SV3344-6RC is an instantaneous RCCB. Siemens specifies that the switching function is not short-time delayed.
This means the device responds without an intentionally introduced short-time delay when the specified residual-current threshold is reached.
The corresponding Siemens 5SV3344-6 has a specified 10 kA short-circuit current rating. Siemens also specifies a maximum permissible series-fuse rating of 80 A for this article.
The RCCB should nevertheless be coordinated with suitable upstream overcurrent protection and the prospective short-circuit conditions of the installation.
An RCCB primarily provides residual-current protection and should not be treated as a substitute for an MCB or MCCB for overload and short-circuit protection unless the complete protection arrangement specifically provides those functions.
The India product description specifies 4MW, meaning 4 module width.
The 4MW designation refers to the physical modular width of the device and does not mean a 4 MW power rating.
The compact modular construction is suitable for:
Distribution boards
Electrical control panels
PCC panels
Sub-distribution boards
Commercial switchboards
Industrial protection assemblies
The corresponding 5SV3344-6 is classified as a size 1 installation device according to DIN 43880 and uses 60 mm grid spacing.
This supports installation in conventional modular electrical distribution assemblies.
The RCCB can be combined with compatible MCBs, busbars and other protective accessories according to the panel design.
Siemens specifies IP20 protection when the device is installed in a suitable distribution board with connected conductors.
The RCCB should therefore be installed inside an appropriate electrical enclosure or distribution assembly.
Residual current occurs when part of the electrical current flows outside the intended circuit path, such as through an unintended leakage path to earth.
The RCCB monitors the current balance and disconnects the protected circuit when the residual current reaches the configured 30 mA threshold.
This provides an additional layer of residual-current protection within the overall electrical safety system.
The Type A characteristic makes this RCCB suitable for installations where residual currents may include pulsating DC components.
Potential applications include:
Industrial automation equipment
Electronic control panels
Rectifier-based machinery
Variable-speed equipment
Commercial electronic equipment
Modern machine installations
Power-electronic loads
The actual suitability should be verified against the residual-current characteristics of the connected equipment.
The 5SV3344-6RC can be considered for compatible:
Industrial distribution boards
Commercial electrical panels
Three-phase feeder circuits
PCC and MCC panels
Factory electrical systems
Building distribution systems
Machine supply circuits
Sub-distribution boards
The combination of:
40 A + 30 mA + Type A + 4-pole / 3+N
makes this article suitable for selected three-phase residual-current protection applications.
Panel builders can use it where the protection design requires a Type A RCCB with a 40 A rated current and 30 mA residual-current threshold.
RCCBs should be included in the electrical installation's regular inspection and testing program.
The test function should be operated according to the manufacturer's instructions and applicable electrical-maintenance requirements to verify correct residual-current tripping.
Regular testing helps confirm that the protective mechanism remains operational.
Before selecting the 5SV3344-6RC, verify:
Rated current: 40 A
Residual-current sensitivity: 30 mA
RCCB type: Type A
Pole configuration: 4-pole / 3+N
System voltage compatibility
Upstream overcurrent protection
Available panel space: 4 module width
Conductor size and termination
Connected equipment leakage-current characteristics
Applicable national electrical regulations
The RCCB type should be selected according to the actual load and residual-current waveform.
The 5SV4344-0RC is a 40 A, 4-pole, Type AC, 30 mA RCCB, whereas the 5SV3344-6RC is a 40 A, 4-pole, Type A, 30 mA RCCB.
Therefore:
5SV3344-6RC → Type A, 40 A, 30 mA
5SV4344-0RC → Type AC, 40 A, 30 mA
The main difference is the residual-current type.
The 5SV3346-6RC is the corresponding 63 A, 4-pole, Type A, 30 mA version.
Therefore:
5SV3344-6RC → 40 A
5SV3346-6RC → 63 A
The main difference is the rated current.
The 5SV3644-6RC belongs to the Type A family with a higher residual-current threshold.
The 5SV3344-6RC is specifically the 30 mA version, while selection of a 300 mA device depends on the required protection scheme.
Type B RCCBs are designed for a broader range of residual-current waveforms than Type A.
The 5SV3344-6RC is specifically a Type A, instantaneous RCCB and should not be replaced by another RCCB type without verifying the protection requirements of the connected equipment.
A selective RCCB incorporates intentional time grading for coordination with other residual-current protective devices.
The 5SV3344-6RC is instantaneous, so it does not provide selective time delay.
The 5SV3342-6RC is the corresponding Type A, 25 A, 4-pole, 30 mA variant in the same product family.
The 5SV3344-6RC is selected when the required rated current is 40 A.
The 5SV3346-6RC is rated at 63 A, whereas the 5SV3344-6RC is rated at 40 A.
Both are Type A, 4-pole RCCBs with 30 mA residual-current sensitivity.
The Siemens 5SV3344-6RC is relevant for:
Electrical panel builders
Industrial buyers
Electrical contractors
Commercial electrical contractors
Facility-maintenance teams
OEMs
Machine builders
Electrical distributors
Factory maintenance departments
Electrical product dealers
