The Siemens Betagard 5SV4646-0RC is a residual current operated circuit breaker (RCCB) from the Siemens SENTRON 5SV4 range. It is designed for electrical networks where protection against AC residual currents is required. The device is rated at 63 A, has a 4-pole / 3+N configuration, 300 mA residual operating current, and Type AC residual-current protection. Siemens documentation identifies it as an instantaneous RCCB with a 10 kA short-circuit current rating and 240/415 V AC supply range.
The 5SV4646-0RC belongs to the Siemens Betagard/SENTRON 5SV4 RCCB family. Its primary purpose is to disconnect the protected circuit when an unwanted residual current reaches the specified trip threshold.
With four poles, it is designed for three-phase plus neutral installations, making it suitable for industrial and commercial distribution circuits. Siemens specifies the device as an instantaneous, 4-pole, Type AC RCCB.
The 5SV4646-0RC has a rated current of 63 A.
This rating makes it suitable for compatible distribution feeders and electrical circuits where a 63 A RCCB is required. The connected load and upstream protection should be designed according to the complete electrical installation.
The RCCB has a rated residual operating current of 300 mA.
When the residual current reaches the specified operating threshold, the device trips and disconnects the protected circuit.
The 300 mA sensitivity is intended for installations requiring this level of residual-current protection. The correct RCCB sensitivity should always be selected according to the protection design and applicable electrical requirements.
The 5SV4646-0RC is a Type AC RCCB.
Type AC RCCBs are intended for protection against sinusoidal alternating residual currents. The correct RCCB type should be selected according to the types of leakage currents that may occur in the electrical installation.
The device provides 4 poles, suitable for a three-phase plus neutral electrical network.
The 3+N arrangement allows the three phases and neutral to be included in the RCCB switching arrangement.
Typical applications include:
Three-phase distribution boards
Industrial feeders
Commercial electrical panels
PCC panels
Sub-distribution boards
Machine supply circuits
Factory electrical systems
The product's India designation identifies the device for 415 V AC applications. Siemens technical data specifies a supply-voltage range of 240/415 V AC, with 415 V applicable across the line conductors and 240 V line-to-neutral.
This makes it suitable for compatible three-phase low-voltage distribution systems.
The 5SV4646-0RC is specified as an instantaneous RCCB. Siemens documentation states that the device does not have a short-time delayed switching function.
This means the RCCB is designed to respond without an intentional delay when the residual-current threshold is reached.
Siemens specifies a 10 kA short-circuit current rating for the device/article family.
The RCCB should still be installed with appropriate upstream overcurrent protection and coordinated with the prospective short-circuit conditions of the installation.
An RCCB provides residual-current protection and should not automatically be treated as a substitute for a circuit breaker providing overload and short-circuit protection.
The device has a specified rated insulation voltage of 2,000 V and overvoltage category III.
These characteristics are relevant when integrating the RCCB into industrial and commercial electrical distribution systems.
The 5SV4646-0RC is designed for installation in standard distribution assemblies and modular electrical panels.
Its 4-pole configuration and 60 mm grid spacing make it suitable for conventional DIN-type distribution-board installations.
A residual current occurs when part of the electrical current flows through an unintended path, such as leakage to earth.
The RCCB monitors the current balance in the circuit and trips when the residual current reaches the configured operating level.
This provides an important layer of electrical protection in installations where residual-current protection is required.
The Siemens 5SV4646-0RC can be considered for:
Industrial distribution panels
Commercial distribution systems
Three-phase feeder protection
Main and sub-distribution boards
PCC panels
Electrical control panels
Factory electrical systems
Machine feeders
Building electrical distribution
Equipment protection circuits
The device can be used by panel builders for three-phase electrical circuits where 63 A, 300 mA, Type AC, 4-pole residual-current protection is appropriate.
It is particularly suitable for systems where all three phases and the neutral need to be incorporated into the residual-current protection arrangement.
Residual-current protection devices should be included in an appropriate inspection and testing program.
The RCCB should be tested according to the manufacturer's instructions and applicable installation requirements. Regular testing can help confirm that the residual-current tripping mechanism is functioning correctly.
Before selecting the 5SV4646-0RC, verify:
Rated current: 63 A
Residual-current sensitivity: 300 mA
RCCB type: AC
Pole configuration: 4-pole / 3+N
System voltage compatibility
Upstream short-circuit protection
Conductor size and termination
Applicable local electrical regulations
Siemens documentation also notes that use of the product may be subject to national regulations and country-specific restrictions.
The 5SV4446-0RC is another 63 A, 4-pole, Type AC RCCB, but with a different residual-current sensitivity.
The key selection difference is the residual-current threshold:
5SV4646-0RC → 300 mA
5SV4446-0RC → 100 mA
The correct sensitivity should be selected according to the protection design.
The 5SV4346-0RC is the 30 mA version in the corresponding 63 A, 4-pole, Type AC family.
Therefore:
5SV4346-0RC → 30 mA
5SV4446-0RC → 100 mA
5SV4646-0RC → 300 mA
This range allows selection according to the required residual-current protection level.
The 5SV4647-0RC is the higher-current version with an 80 A rated current, while the 5SV4646-0RC is rated at 63 A. Both are 4-pole, Type AC, 300 mA RCCBs.
Therefore:
5SV4646-0RC → 63 A
5SV4647-0RC → 80 A
