1SDA071169R1 ABB E4.2H 3200 Ekip Hi-Touch LSIG 3p F HR Air Circuit Breaker

Why Choose the ABB E4.2H 3200 Ekip Hi-Touch LSIG 3p F HR Air Circuit Breaker?

The ABB E4.2H 3200 Ekip Hi-Touch LSIG 3p F HR, order code 1SDA071169R1, is a high-performance 3200 A three-pole air circuit breaker (ACB) designed for advanced protection, switching and isolation in demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 series, it combines the E4.2H performance class with fixed mounting, rear horizontal terminals and the advanced Ekip Hi-Touch LSIG electronic trip unit.

The E4.2H 3200 platform provides an ultimate short-circuit breaking capacity of 100 kA at 415 V AC and 85 kA at 690 V AC. Its high continuous-current rating and substantial fault interruption capability make it particularly suitable for main distribution systems where high prospective short-circuit currents require dependable protection.

Protection is provided by the Ekip Hi-Touch LSIG solid-state electronic release, delivering long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. The breaker is supplied in a fixed three-pole configuration with rear horizontal terminals and is fitted with four auxiliary contacts plus open/closed breaker position indication.
