Why Choose the ABB 1SDA070741R1 E1.2B 800 Ekip Dip LI Air Circuit Breaker?
The ABB 1SDA070741R1 is a SACE Emax 2 E1.2B 800 three-pole fixed air circuit breaker with front terminals and an Ekip Dip LI solid-state electronic trip unit. Designed for AC low-voltage power distribution, it combines an 800 A rated current with dependable overload and instantaneous short-circuit protection in a compact E1.2 frame.
This E1.2B configuration provides a 42 kA ultimate short-circuit breaking capacity at 400–440 V AC, with the same 42 kA rating maintained up to 690 V AC. It also provides a 42 kA short-time withstand current for 1 second and 24 kA for 3 seconds, supporting robust performance in industrial and commercial distribution systems.
The Ekip Dip LI release provides long-time overload and instantaneous short-circuit protection. The breaker is supplied with four auxiliary contacts and circuit-breaker open/closed position indication, providing useful status interfaces for compatible switchboard control and monitoring arrangements.
