PrincipleABB SACE TMAX XT1S 160 TMD 63A 4P uses bimetallic strip for overload protection; when the load current exceeds setting value, the bimetallic strip heats and bends to trigger the mechanism and open the contacts. The molded case circuit breaker adopts magnetic coil for short-circuit protection; under large short-circuit current, the electromagnetic coil generates instant suction to trip the breaker quickly. The arc extinguishing chamber cools and cuts off the electric arc during breaking. Auxiliary contacts change state synchronously to send fault signals to the control system. When abnormal heating or internal component aging occurs, ABB SACE TMAX XT1S 160 TMD 63A 4P may trip abnormally for inspection.

ApplicationsABB SACE TMAX XT1S 160 TMD 63A 4P is widely deployed in chemical plants, water treatment stations, factory workshops, commercial buildings and new energy auxiliary power cabinets. The molded case circuit breaker undertakes main and branch circuit protection of pumps, fans, conveyor motors and general power loads. It cooperates with contactors, thermal relays, PLC and HMI to form a complete power control and protection system. ABB SACE TMAX XT1S 160 TMD 63A 4P is a preferred imported spare for low-voltage distribution and automation power loops.
