1SDA104474R1 ABB E2.2H/E9 2000 Ekip Touch LSIG 3P WMP Air Circuit Breaker 900V

Why Choose the ABB 1SDA104474R1 Emax 2 Air Circuit Breaker?

The ABB 1SDA104474R1 is a high-performance SACE Emax 2 E2.2H/E9 air circuit breaker (ACB) designed for protection and switching in demanding high-current electrical distribution systems. Configured as an E2.2H/E9 2000 Ekip Touch LSIG 3p WMP 900V, this three-pole withdrawable moving part combines a 2000 A rated current with ABB's advanced Ekip Touch LSIG electronic protection trip unit.

Part of the ABB SACE Emax 2/E9 range, the E2.2H/E9 is engineered for higher-voltage low-voltage distribution applications operating at up to 900 V AC. The H breaking-capacity execution provides an ultimate short-circuit breaking capacity of 65 kA at 900 V AC, making it suitable for installations with substantial prospective fault currents.

The integrated Ekip Touch LSIG trip unit provides long-time, short-time, instantaneous and ground-fault protection through ABB's touchscreen-based Ekip platform. The withdrawable construction supports maintainable switchboard designs, while four auxiliary contacts and circuit-breaker open/closed position indication provide useful signalling functions for control and supervision systems.
