Product Description:
The CHINT NXMLE-160S/3300 160A Earth Leakage MCCB is a fully integrated 3-pole molded case circuit breaker with built-in residual current protection, offering advanced electrical safety for 3-phase installations. Rated at 160A, this MCCB combines thermal, magnetic, and earth leakage protection in one unit—ideal for high-capacity systems where ground fault detection is critical.

Equipped with adjustable sensitivity settings of 100mA, 200mA, or 300mA, it ensures adaptable protection against electric shock and fire risks due to insulation faults or current leakage. Its high breaking capacity of 36kA at 400V makes it suitable for demanding industrial, commercial, and infrastructure applications.
