Why Choose the Chint NM8L-125S-3P-100A-X1-T1 MCCB with RCD?
The Chint NM8L-125S-3P-100A-X1-T1 is a dependable 3-pole moulded case circuit breaker (MCCB) with integrated residual current protection (RCD), designed for low-voltage electrical systems requiring protection against overloads, short circuits and earth leakage faults. It combines core circuit breaker protection with residual current disconnection in one compact unit, making it suitable for industrial, commercial and OEM electrical installations.
As part of the Chint NM8L series, this breaker uses an adjustable thermal magnetic trip unit together with RCD protection to help improve both equipment protection and personnel safety. Its combined design reduces the need for separate devices, helping simplify panel layouts while maintaining reliable protection for three-phase circuits.
With a rated current of 100 A and a 3-pole configuration, the NM8L-125S-3P-100A-X1-T1 is ideal for three-phase distribution systems, machinery panels, motor control centres and switchboards where robust circuit protection and earth leakage detection are essential.

Reliable Circuit and Earth Leakage Protection
MCCBs with integrated residual current protection provide a practical solution for electrical systems where both equipment protection and earth leakage monitoring are required. The MCCB section protects against overload and short-circuit faults, while the residual current function disconnects the circuit when earth leakage is detected.
The Chint NM8L-125S-3P-100A-X1-T1 helps support safer operation in three-phase installations by combining multiple protection functions within a single panel-mounted device. This makes it well suited to modern switchboards, machinery systems and distribution panels where reliability and space efficiency are important.
Typical Applications
- Three-phase distribution boards.
- Industrial control panels.
- Commercial electrical installations.
- Motor control centres.
- Machinery and automation systems.
- OEM switchboards and panel building.
