1SDA071736R1 ABB E4.2V 2000 Ekip Touch LSIG 4p F HR Air Circuit Breaker 2000 A

Why Choose the ABB E4.2V 2000 Ekip Touch LSIG 4p F HR Air Circuit Breaker?

The ABB E4.2V 2000 Ekip Touch LSIG 4p F HR, order code 1SDA071736R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution systems, it combines a 2000 A rated uninterrupted current with an Ekip Touch LSIG electronic trip unit for comprehensive overload, selective short-circuit, instantaneous short-circuit and earth-fault protection.

The Ekip Touch LSIG release provides configurable long-time, short-time, instantaneous and earth-fault protection through ABB's touchscreen-based Ekip interface. This combination enables detailed protection coordination while giving operators convenient access to breaker settings, measurements and operating information.

The E4.2V is ABB's very-high-breaking-capacity configuration in this frame size, providing a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 s. Combined with four-pole fixed construction and rear horizontal terminals, the 1SDA071736R1 is engineered for installations with exceptionally high prospective fault currents.
