The Siemens 5SV4347-0RC 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 an 80 A rated current and 30 mA rated residual operating current. Siemens identifies the corresponding 5SV4347-0 article as an instantaneous 4-pole Type AC RCCB, rated at 80 A and 30 mA for 400 V AC systems.
The 5SV4347-0RC 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 arrangement makes the device suitable for three-phase systems with neutral. Siemens' 2025 product catalogue lists the 5SV4 Type AC 3P+N range in a 4-module format, including 30 mA variants and the 80 A 5SV4347-0 article.
The RCCB has a rated current of 80 A.
This makes the device suitable for compatible higher-current three-phase distribution circuits and feeders where an 80 A residual-current protection device is required.
The protected circuit should be designed so that the RCCB operates within its rated current and installation conditions.
The 5SV4347-0RC 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.
A 30 mA RCCB is commonly selected where the protection design calls for a lower residual-current threshold. The exact use should be determined according to the electrical installation design and applicable regulations.
The device is a Type AC RCCB.
Type AC residual-current devices are designed for compatible sinusoidal alternating residual currents. The RCCB type should always be selected according to the residual-current waveform that can occur in the actual installation.
The 5SV4347-0RC uses 4 poles, making it suitable for three-phase plus neutral circuits.
This arrangement allows the three phases and neutral to be incorporated into the residual-current protection arrangement.
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 description identifies the device as 415 V AC. Siemens' technical documentation for the corresponding 5SV4347-0 specifies 400 V AC rated operating voltage for the article.
For the SB Smart listing, the 415 V India-market designation can be retained, while the actual system voltage should be checked against the Siemens technical rating and the electrical installation requirements.
The 5SV4347-0RC is an instantaneous RCCB. Siemens specifies that the corresponding 5SV4347-0 does not have a short-time delayed switching function.
This means the RCCB responds without an intentional short-time delay when the specified residual-current threshold is reached.
Siemens' 2025 technical data for the 5SV4 Type AC family specifies a 10 kA short-circuit current rating for the corresponding 80 A, 30 mA device.
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 automatically be treated as a replacement for an MCB or MCCB for overload and short-circuit protection.
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 indicate a 4 MW power rating.
The Siemens catalogue identifies the Type AC 3P+N family as 4 MW, making the device suitable for conventional modular distribution-board arrangements.
The 5SV4347-0RC is designed for modular electrical distribution installations.
Its 4-pole construction can be integrated with compatible MCBs, busbars and other electrical-protection accessories in suitably designed panels.
This makes the device appropriate for panel builders working with standard modular protection assemblies.
Residual current occurs when part of the electrical current leaves its intended circuit path, such as through an unintended earth-leakage route.
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 important residual-current protection layer within the overall electrical safety system.
The 5SV4347-0RC 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:
80 A + 30 mA + Type AC + 4-pole / 3+N
This combination makes the product relevant for selected higher-current three-phase residual-current protection applications.
The suitability of 30 mA protection must be assessed against the complete installation design, load characteristics and applicable 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 maintenance requirements to verify correct residual-current tripping.
Regular testing helps confirm that the protective mechanism remains functional.
Before selecting the 5SV4347-0RC, verify:
Rated current: 80 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 specifically warns that these devices are 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 RCCB, while 5SV4347-0 is rated at 80 A. Siemens' product data identifies the 40 A article and the 80 A article within the same Type AC 3P+N family.
Therefore:
5SV4344-0RC → 40 A, 30 mA
5SV4347-0RC → 80 A, 30 mA
The main difference is the rated current.
The 5SV4346-0 is the corresponding 63 A, 4-pole, Type AC, 30 mA variant.
Therefore:
5SV4346-0RC → 63 A
5SV4347-0RC → 80 A
This distinction is important when selecting an exact replacement because the rated current must match the intended circuit and protection design.
The 5SV4447-0 is the corresponding 80 A, 4-pole, Type AC, 100 mA variant.
Therefore:
5SV4347-0RC → 80 A, 30 mA
5SV4447-0RC → 80 A, 100 mA
The key difference is the residual-current operating threshold.
The 5SV4647-0 is the corresponding 80 A, 4-pole, Type AC, 300 mA variant.
Therefore:
5SV4347-0RC → 80 A, 30 mA
5SV4447-0RC → 80 A, 100 mA
5SV4647-0RC → 80 A, 300 mA
The correct sensitivity should be selected according to the protection function required by the electrical installation.
The 5SV4342-0 is the corresponding 25 A, 4-pole, Type AC, 30 mA version.
The 5SV4347-0RC provides the same Type AC and 30 mA characteristics with a higher 80 A rated current.
The Siemens 5SV4347-0RC is relevant for:
Electrical panel builders
Industrial buyers
Electrical contractors
Commercial electrical contractors
Facility-maintenance teams
Machine builders
OEMs
Electrical distributors
Factory maintenance departments
Electrical product dealers
