Why Choose the ABB E1.2B 630 Ekip Touch LSIG 3-Pole Air Circuit Breaker?
The ABB 1SDA070706R1 is a SACE Emax 2 E1.2B air circuit breaker designed for protection, switching and isolation in low-voltage AC power distribution systems. Rated at 630 A, this three-pole circuit breaker combines the compact E1.2 frame with ABB's advanced Ekip Touch LSIG solid-state trip unit.
The integrated Ekip Touch LSIG release provides long-time (L), short-time (S), instantaneous (I) and ground-fault (G) protection functions. This comprehensive protection package enables the circuit breaker to respond to overloads, short circuits and ground faults while providing the advanced interface and functionality associated with the Ekip Touch family.
The 1SDA070706R1 features a three-pole fixed (F) construction with front terminals (F) and an R630 rating plug. The E1.2B platform provides an ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a short-time withstand current of 42 kA for 1 s, making it suitable for demanding industrial, commercial and infrastructure distribution systems.
