Product Description:
The CHINT NXMLE-160S/3300 125A Earth Leakage MCCB is a high-performance 3-pole molded case circuit breaker with built-in earth leakage protection, ideal for industrial and commercial 3-phase systems. This unit offers adjustable residual current sensitivity of 100mA / 200mA / 300mA, delivering flexible and precise protection against electric shocks and fire hazards caused by earth faults.

Built on the NXMLE-160 frame, it integrates thermal, magnetic, and earth leakage protection in one device, eliminating the need for separate RCCBs and MCCBs. With a rated current of 125A, it ensures both overload and short-circuit protection alongside leakage detection, complying with IEC 60947-2 and safety standards.
