Why Choose the ABB XT7H M 1250 Ekip Dip LIG Circuit Breaker?
The ABB XT7H M 1250 Ekip Dip LIG, order code 1SDA101492R1, is a high-performance three-pole moulded case circuit breaker (MCCB) designed for demanding low-voltage power distribution applications. Part of the ABB SACE Tmax XT family, this configuration combines a 1250 A rated current with an Ekip Dip LIG solid-state electronic protection release.
The Ekip Dip LIG trip unit provides long-time overload, instantaneous short-circuit and earth-fault protection functions. This combination provides electronic protection against major electrical fault conditions while omitting the short-time protection function found on LSI and LSIG releases, making it suitable for distribution systems where an LIG protection configuration is specified.
The XT7H M configuration combines a three-pole design with fixed construction, front terminals and the XT7M stored-energy operating mechanism. Its H performance level provides a short-circuit breaking capacity of 70 kA, making the breaker suitable for high-current switchboards and distribution systems with demanding prospective fault levels.
