Why Choose the ABB E2.2N 1250 Ekip G Touch LSIG 3P Air Circuit Breaker?
The ABB E2.2N 1250 Ekip G Touch LSIG 3P, order code 1SDA070957R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for generator protection, control and switching in demanding low-voltage electrical distribution systems. Part of the ABB Emax 2 E2.2 series, this fixed three-pole circuit breaker combines a rated uninterrupted current of 1250 A with the generator-oriented Ekip G Touch LSIG solid-state electronic trip unit.
The Ekip G Touch LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection together with generator-focused protection functionality. Its electronic architecture supports accurate protection settings, measurement and selective coordination, helping protect generators, cables, busbars and connected equipment against damaging electrical faults.
The E2.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 440 V AC and a rated short-time withstand current of 66 kA for 1 s. This configuration is a fixed three-pole breaker with rear horizontal terminals and is fitted with four auxiliary changeover contacts plus circuit-breaker open/closed position indication.
