NZML4-AE800 Eaton Molded Case Circuit Breaker

The NZML4-AE800 is an 800A molded case circuit breaker with adjustable overload release from 400A to 800A and adjustable short-circuit protection spanning 1600A to 9600A. It is designed for industrial environments where precise, field-configurable trip settings are required. The device complies with applicable MCCB standards for uninterrupted current rating and trip adjustment ranges as specified. Its construction supports sustained operation under demanding electrical loads without derating beyond the stated 800A nominal current capacity. Adjustment mechanisms allow configuration of both thermal (overload) and magnetic (short-circuit) trip thresholds within the defined limits. The unit is intended for integration into main distribution panels, motor control centers, and other fixed industrial power systems requiring coordinated overcurrent protection.
