1SDA072435R1 ABB E2.2H 2500 Ekip Touch LSI 3p WMP Air Circuit Breaker 2500 A

Why Choose the ABB E2.2H 2500 Ekip Touch LSI 3p WMP Air Circuit Breaker?

The ABB E2.2H 2500 Ekip Touch LSI 3p WMP, order code 1SDA072435R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. With a 2500 A rated current and ABB's advanced Ekip Touch LSI electronic trip unit, it provides long-time, short-time and instantaneous overcurrent protection.

The E2.2H combines high current-carrying capability with a high short-circuit breaking performance. This H-performance model provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC, making it suitable for industrial, infrastructure and commercial distribution systems with high prospective fault currents.

The 1SDA072435R1 is the moving part of a withdrawable circuit breaker and features a three-pole configuration. It has a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and rated impulse withstand voltage of 12 kV. The breaker is also fitted with four auxiliary contacts and circuit-breaker open/closed position indication.
