Why Choose the Chint NM8L-125S-4P-125A-X1-T1 MCCB with RCD?
The Chint NM8L-125S-4P-125A-X1-T1 is a robust 4-pole moulded case circuit breaker (MCCB) with integrated residual current protection (RCD), designed to protect low-voltage electrical installations against overloads, short circuits and earth leakage faults. By combining MCCB and RCD functions within one compact device, it provides a reliable protection solution for industrial, commercial and OEM power distribution systems.
As part of the Chint NM8L series, this breaker features an adjustable thermal magnetic trip unit together with integrated residual current protection. Its 4-pole construction allows protection and isolation of three-phase and neutral conductors, making it suitable for installations where complete circuit disconnection and enhanced electrical safety are required.
With a rated current of 125 A and a 4-pole configuration, the NM8L-125S-4P-125A-X1-T1 is ideal for switchboards, distribution panels, machinery systems and motor control applications requiring dependable overcurrent and earth leakage protection.
