Circuit-breaker LZMC1-A160-I - 111897 provides overload and short-circuit protection for 40-1600 A three-phase circuits. The LZM ACB features adjustable overcurrent and short-circuit releases with no derating up to +50°C. It allows vertical mounting with 90° positions possible in all directions and is designed in accordance with EN 60947-2. The switches and circuit-breakers have uniform dimensions and include a mounting option for voltage isolators. Auxiliary contacts are available for signaling switch states. The actuator is directly pivoted and mounted on the circuit-breaker with a hinged door for remote operation.
