1SDA069628R1 ABB XT4H 160 Ekip E-LSIG 100A 4P MCCB

Why Choose the ABB XT4H 160 Ekip E-LSIG 1SDA069628R1 Circuit Breaker?

The ABB XT4H 160 Ekip E-LSIG 1SDA069628R1 is a high-performance four-pole moulded case circuit breaker (MCCB) designed for reliable protection of low-voltage AC power distribution systems. Part of the ABB SACE Tmax XT4 range, it combines the compact XT4H 160 frame with a 100 A Ekip E-LSIG electronic trip unit for comprehensive overload, short-circuit and earth-fault protection.

This XT4H circuit breaker is supplied in a fixed configuration with front terminals and features four poles for applications requiring switching and protection across three phases and neutral. The Ekip E-LSIG solid-state release provides long-time, short-time, instantaneous and ground-fault protection functions, allowing the breaker to provide sophisticated electronic protection in industrial and commercial distribution systems.

The XT4H performance level provides a rated ultimate short-circuit breaking capacity of 70 kA at 415 V AC, while the breaker has a rated operational voltage of 690 V AC. Its combination of high breaking capacity, electronic protection and compact construction makes the 1SDA069628R1 particularly suitable for demanding switchboard and power distribution applications.
