Chint NL1-63-263/30-A residual current circuit breaker, a 63A 2 pole 30mA Type A RCCB designed for earth leakage and residual current protection in low voltage electrical installations.
£18.09
The Chint NL1-63-263/30-A is a dependable residual current circuit breaker designed to provide earth leakage protection in low voltage electrical installations. As part of the Chint NL1-63 RCCB series, it detects residual current faults and disconnects the circuit when leakage current is present, helping improve electrical safety in domestic, commercial and light industrial distribution systems.
This model features Type A residual current protection, making it suitable for circuits where pulsating DC residual currents may occur. It is commonly used where modern electrical equipment, electronic power supplies, appliances and control devices are installed, offering enhanced protection compared with standard AC type RCCBs.
With a 63A rated current, 2 pole configuration and 30mA residual current sensitivity, the NL1-63-263/30-A is ideal for single-phase circuits requiring additional protection against electric shock and earth leakage faults.
Residual current circuit breakers monitor the current flowing through live and neutral conductors. If an imbalance is detected, caused by leakage to earth, the RCCB trips and disconnects the circuit to help reduce the risk of electric shock and electrical fire.
The Type A protection of the Chint NL1-63-263/30-A makes it suitable for installations containing equipment that may generate pulsating DC residual currents, such as electronic appliances, control systems and modern power supplies. Its compact design allows straightforward integration into consumer units and distribution boards.

It is used to provide residual current and earth leakage protection in low voltage electrical installations.
The NL1-63-263/30-A has a rated current of 63A.
The 30mA rating refers to the residual operating current sensitivity, meaning the device is designed to trip when earth leakage reaches approximately 30mA.
Type A means the device is designed to detect both sinusoidal AC residual currents and pulsating DC residual currents.
No. An RCCB provides residual current protection only and should be used with suitable overcurrent protection such as an MCB or fuse.
Chint NL1-63 Type A RCCBs are trusted by electricians, panel builders and contractors for reliable residual current protection, compact installation and dependable performance in modern low voltage distribution systems.
