The Siemens 5SV4346-0RC is a SENTRON 5SV4 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 AC RCCB with a 63 A rated current and 30 mA rated residual operating current. Siemens identifies the corresponding 5SV4346-0 as a 4-pole Type AC RCCB rated at 63 A, 30 mA and 400 V AC, while the India product designation specifies 415 V, 4-module format.
The 5SV4346-0RC belongs to the Siemens SENTRON 5SV4 RCCB family. Its purpose is to detect residual current in the protected circuit and disconnect the circuit when the residual current reaches the specified operating threshold.
The 4-pole / 3+N configuration makes this device suitable for three-phase systems with neutral and for compatible industrial, commercial and distribution applications. Siemens' current product data identifies the device as an instantaneous 4-pole Type AC RCCB.
The RCCB has a rated current of 63 A.
This makes the device suitable for compatible three-phase distribution circuits and feeders designed for a 63 A residual-current protection device.
The connected circuit should be designed so that the RCCB operates within its specified electrical ratings and installation conditions.
The 5SV4346-0RC has a rated residual operating current of 30 mA.
When the residual current reaches the specified operating threshold, the RCCB trips and disconnects the protected circuit.
The 30 mA sensitivity is used where the electrical protection design requires a lower residual-current operating threshold. Its suitability should be determined according to the complete installation design and applicable regulations.
The device is a Type AC RCCB.
Type AC residual-current devices are intended for compatible sinusoidal alternating residual currents. The correct RCCB type must be selected according to the waveform of residual current that can occur in the actual installation.
The 5SV4346-0RC has 4 poles, suitable for three-phase plus neutral circuits.
This arrangement allows the three phases and neutral to be incorporated into the residual-current protection system.
Typical applications include:
Three-phase distribution boards
Industrial feeder circuits
PCC panels
MCC panels
Commercial electrical panels
Sub-distribution boards
Machine supply circuits
Factory electrical systems
The supplied India product designation identifies the article for 415 V AC systems, while Siemens' current Industry Mall data specifies 400 V AC for the corresponding 5SV4346-0 article.
For the SB Smart listing, the 415 V India designation can be retained, while the exact installation should be checked against the current Siemens rating and the actual electrical system.
The 5SV4346-0RC is an instantaneous RCCB. Siemens specifies that the corresponding device does not have a short-time delayed switching function.
This means the device responds without an intentional short-time delay when the residual-current threshold is reached.
The corresponding 5SV4346-0 is specified with a 10 kA short-circuit current rating.
The RCCB should nevertheless be coordinated with appropriate 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 designation specifies 4MW, meaning 4 module width.
The 4MW designation refers to the physical modular width and does not represent a 4 MW power rating.
This format is suitable for:
Modular distribution boards
Electrical control panels
PCC panels
Sub-distribution boards
Commercial switchboards
Industrial protection assemblies
The 5SV4 RCCB is designed for integration into modular electrical distribution assemblies.
The device can be installed alongside compatible MCBs, busbars and other protective accessories according to the panel design.
Siemens documentation also identifies a 60 mm grid spacing for this device.
Residual current occurs when part of the electrical current leaves the intended circuit path, for example through an unintended earth-leakage path.
The RCCB monitors the relevant current balance and disconnects the protected circuit when the residual current reaches the 30 mA operating threshold.
This provides an additional layer of residual-current protection within the overall electrical safety system.
The 5SV4346-0RC 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 device is particularly relevant where the protection design requires:
63 A + 30 mA + Type AC + 4-pole / 3+N
This combination makes the RCCB suitable for selected three-phase distribution and feeder applications.
The use of a 30 mA device should be evaluated against the load characteristics, leakage-current conditions and applicable protection requirements.
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 5SV4346-0RC, verify:
Rated current: 63 A
Residual-current sensitivity: 30 mA
RCCB type: Type AC
Pole configuration: 4-pole / 3+N
System voltage compatibility
Upstream overcurrent protection
Available panel space: 4 module width
Conductor size and termination
Applicable national electrical regulations
Siemens explicitly notes that the use of these devices is not permitted in all countries and that national installation regulations must be observed.
The 5SV4344-0 is the corresponding 40 A, 4-pole, Type AC, 30 mA version, while the 5SV4346-0 is rated at 63 A.
Therefore:
5SV4344-0RC → 40 A, 30 mA
5SV4346-0RC → 63 A, 30 mA
The main difference is the rated current of the protected circuit.
The 5SV4347-0RC is the corresponding 80 A, 4-pole, Type AC, 30 mA version.
Therefore:
5SV4346-0RC → 63 A
5SV4347-0RC → 80 A
Both belong to the same Type AC, 4-pole, 30 mA family.
The 5SV4446-0RC is the corresponding 63 A, 4-pole, Type AC, 100 mA version.
Therefore:
5SV4346-0RC → 63 A, 30 mA
5SV4446-0RC → 63 A, 100 mA
The principal difference is the residual-current operating threshold.
The 5SV4646-0RC is the corresponding 63 A, 4-pole, Type AC, 300 mA version.
Therefore:
5SV4346-0RC → 63 A, 30 mA
5SV4446-0RC → 63 A, 100 mA
5SV4646-0RC → 63 A, 300 mA
The correct residual-current sensitivity should be selected according to the electrical protection design.
The 5SV4342-0RC is the corresponding 25 A, 4-pole, Type AC, 30 mA version.
The 5SV4346-0RC provides the same Type AC and 30 mA characteristics with a higher 63 A rated current.
The Siemens 5SV4346-0RC is relevant for:
Electrical panel builders
Industrial buyers
Electrical contractors
Commercial electrical contractors
Facility-maintenance teams
Machine builders
