155 MBFREQUENTLY ASKED QUESTION (FAQ)
What is Westhomes WSBR1-63 RCBO?
Westhomes WSBR1-63 is a residual current circuit breaker with overcurrent protection (RCBO), integrating multiple protection functions including overload protection, short-circuit protection, residual current protection, and overvoltage protection.
With a 6kA breaking capacity and up to 400V rated voltage, WSBR1-63 provides reliable protection for residential, commercial, and industrial low-voltage electrical systems.
What protection functions does WSBR1-63 provide?
WSBR1-63 combines four protection functions in one device:
Overload protection
Short-circuit protection
Residual current leakage protection
Overvoltage protection
This integrated design reduces installation space and improves electrical safety.
What does the 6kA breaking capacity of WSBR1-63 mean?
The 6kA breaking capacity means that WSBR1-63 can safely interrupt a short-circuit current up to 6000A under specified conditions.
A higher breaking capacity allows the RCBO to provide safer protection in systems with higher potential fault currents.
How does WSBR1-63 overvoltage protection work?
The overvoltage protection function monitors abnormal voltage increases in the electrical system.
When the voltage exceeds the preset safety level, the device automatically disconnects the circuit to protect connected electrical equipment from damage caused by excessive voltage.
What is the rated voltage of WSBR1-63 RCBO?
WSBR1-63 is designed for low-voltage AC distribution systems with rated voltage up to 400V.
It is suitable for standard 50Hz/60Hz electrical networks.
What is the difference between RCBO and RCCB?
The main difference is the integrated overcurrent protection.
RCBO combines residual current protection and overcurrent protection.
RCCB only provides residual current (leakage) protection and usually requires an MCB for overload and short-circuit protection.
WSBR1-63 provides a complete protection solution in one device.
What applications are suitable for WSBR1-63 RCBO?
WSBR1-63 is widely used in:
Residential distribution boxes
Commercial buildings
Industrial control panels
Lighting circuits
Socket circuits
Electrical equipment protection
It is suitable for applications requiring enhanced electrical safety.
What pole configurations are available for WSBR1-63?
WSBR1-63 is available in different pole configurations, including:
1P+N
3P+N
These options allow flexible installation in both single-phase and three-phase distribution systems.
What leakage current sensitivity options does WSBR1-63 support?
WSBR1-63 supports different residual current protection levels, such as:
30mA for personal protection
100mA for general protection
300mA for fire prevention applications
The selection depends on the safety requirements of the electrical installation.
Why choose Westhomes WSBR1-63 RCBO?
Westhomes WSBR1-63 provides an all-in-one protection solution by combining overload, short circuit, leakage, and overvoltage protection.
With reliable performance, compact DIN rail installation, and flexible configurations, it helps improve electrical safety and system reliability.
