1SDA100971R1 ABB XT7L 1000 Ekip Touch LSIG 1000 A 3P MCCB

Why Choose the ABB XT7L 1000 Ekip Touch LSIG 1SDA100971R1 Circuit Breaker?

The ABB XT7L 1000 Ekip Touch LSIG 1SDA100971R1 is a high-performance three-pole moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage AC power distribution systems. Part of the ABB SACE Tmax XT7 range, this fixed circuit breaker combines a rated current of 1000 A with ABB's advanced Ekip Touch LSIG electronic trip unit.

The Ekip Touch LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions, giving electrical designers a versatile protection platform for transformers, generators, feeders and distribution systems. The breaker is supplied as a complete device with its protection unit and uses a fixed installation arrangement with front main-circuit connections.

The XT7L performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 400 V AC. The breaker is rated at 1000 A with a rated operational voltage up to 690 V AC, while adjustable overload and short-circuit settings support accurate coordination with the wider electrical distribution system.
