1SDA069627R1 ABB XT4H 160 Ekip E-LSIG 63A 4P MCCB

Why Choose the ABB XT4H 160 Ekip E-LSIG 1SDA069627R1 Circuit Breaker?

The ABB XT4H 160 Ekip E-LSIG 1SDA069627R1 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 advanced ABB SACE Tmax XT4 range, it combines a 160 A frame with a 63 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 of the neutral conductor alongside the three phases. The Ekip E-LSIG solid-state release provides L, S, I and G protection functions, making the breaker suitable for sophisticated distribution systems where adjustable electronic protection is required.

The XT4H performance level provides a rated ultimate short-circuit breaking capacity of 70 kA at 415 V AC, while the breaker supports rated operational voltages up to 690 V AC. Its high breaking capacity, compact construction and electronic protection make the 1SDA069627R1 an effective solution for demanding industrial, commercial and infrastructure power distribution applications.

Advanced Electronic Protection for Power Distribution

The Ekip E-LSIG electronic release provides multiple protection functions for low-voltage distribution circuits. Long-time protection guards against sustained overload conditions, short-time and instantaneous protection respond to short-circuit faults, and the ground-fault function provides additional protection against earth-fault currents. This combination allows the circuit breaker to provide comprehensive protection within modern electrical distribution systems.

The XT4H platform combines this electronic protection with high short-circuit performance, including 70 kA breaking capacity at 415 V AC. Its compact four-pole construction, fixed mounting and front connections make it particularly suitable for switchboards where high fault-current capability, neutral switching and configurable electronic protection are required.
