ABB SACE Tmax XT7M

The XT7M is the stored-energy mechanism version of ABB SACE Tmax XT7 molded case circuit breaker, frame rating up to 1600A, available current ratings 800A, 1000A, 1200A, 1600A, rated operational voltage up to 690V AC. This XT7M supports 3-pole or 4-pole configuration, fixed or withdrawable mounting. The M indicates built-in spring stored-energy mechanism, optional motor operator for remote closing and tripping. It can be equipped with Ekip Dip, Ekip Touch, Ekip Hi-Touch electronic trip units, supporting LI, LSI, LSIG protection functions including overload, short-time delay, instantaneous short-circuit and earth fault protection.

This XT7M complies with IEC 60947-2 standard. The Ekip Hi-Touch variant integrates power measurement, event recording, waveform capture and local graphic display. Optional communication modules support Modbus TCP, PROFINET for power monitoring, fault codes and breaker status transmission to SCADA and energy management systems. Withdrawable models have connected, test and isolated positions for safe maintenance without disconnecting busbars. It carries high short-circuit withstand capacity, available in N, S, H, L breaking grades.

The XT7M is widely used in industrial substations, power plants, photovoltaic and energy storage low voltage distribution cabinets. Tmax XT is ABB’s current mainstream molded case circuit breaker platform. Many electrical contractors and maintenance teams stock the XT7M as spare breaker for panel retrofit and emergency replacement.
