1SDA072308R1 ABB E2.2N 1250 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2N 1250 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker?

The ABB E2.2N 1250 Ekip Hi-Touch LSI 3p WMP, order code 1SDA072308R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and control of low-voltage electrical distribution systems. With a rated uninterrupted current of 1250 A, the breaker combines the E2.2N frame with ABB's advanced Ekip Hi-Touch LSI electronic trip unit.

Designed as a withdrawable moving part, this Emax 2 circuit breaker provides flexible installation, inspection and maintenance in industrial and commercial switchboards. The Ekip Hi-Touch protection unit provides sophisticated electronic protection and monitoring capabilities, with LSI protection functions covering overload, selective short-circuit and instantaneous short-circuit protection.

The E2.2N 1250 offers a rated ultimate short-circuit breaking capacity of 66 kA at 415 V AC and 66 kA at 690 V AC. This three-pole configuration is supplied as the moving part of a withdrawable circuit breaker and is fitted with four auxiliary change-over contacts, making it suitable for demanding power distribution, switchgear and industrial electrical protection applications.
