1SDA101557R1 ABB XT7L M 1600 Ekip Dip LIG 1600 A 3-Pole MCCB

Why Choose the ABB XT7L M 1600 Ekip Dip LIG Circuit Breaker?

The ABB XT7L M 1600 Ekip Dip LIG, order code 1SDA101557R1, 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 1600 A rated uninterrupted 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 electronic protection combination is suited to distribution systems requiring overload and high-current fault protection together with earth-fault protection, while the adjustable overload setting range allows the protection to be configured between 640–1600 A.

The XT7L M configuration combines a three-pole design with fixed construction, front terminals and a stored-energy operating mechanism with lever operation. Its L performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 400 V AC, 50 Hz, making this breaker particularly suitable for high-current switchboards and distribution systems with very high prospective fault levels.
