Chint NM8L-125S-4P-20A-X1-T1 RCD – 4P – 20A
Chint NM8L-125S-4P-20A-X1-T1 20A 4-pole moulded case circuit breaker with integrated residual current protection for overload, short-circuit and earth leakage protection.
Why Choose the Chint NM8L-125S-4P-20A-X1-T1 MCCB with RCD?
The Chint NM8L-125S-4P-20A-X1-T1 is a reliable 4-pole moulded case circuit breaker (MCCB) with integrated residual current protection (RCD), designed to provide protection against overloads, short circuits and earth leakage faults in low-voltage electrical installations. By combining MCCB and RCD protection in one compact unit, it offers a practical solution for commercial, industrial and OEM panel applications.
As part of the Chint NM8L series, this breaker uses an adjustable thermal magnetic trip unit together with residual current protection to help safeguard both connected equipment and personnel. Its 4-pole construction makes it suitable for three-phase plus neutral systems where complete circuit isolation and residual current protection are required.
With a rated current of 20 A and a 4-pole configuration, the NM8L-125S-4P-20A-X1-T1 is ideal for distribution boards, machinery panels, control cabinets and electrical systems requiring dependable disconnection and integrated earth leakage protection.
