Why Choose the ABB E1.2N 250 Ekip Touch LSI 4p WMP Air Circuit Breaker?
The ABB E1.2N 250 Ekip Touch LSI 4p WMP, order code 1SDA072675R1, is a SACE Emax 2 air circuit breaker moving part designed for protection and control in low-voltage electrical distribution systems. Part of the ABB SACE Emax 2 E1.2 series, this four-pole withdrawable breaker combines a 250 A rated uninterrupted current with the advanced Ekip Touch LSI electronic trip unit.
The Ekip Touch LSI release provides long-time overload, short-time delayed and instantaneous short-circuit protection. Its electronic touchscreen platform enables straightforward protection configuration and monitoring, while adjustable protection settings help coordinate the breaker with cables, transformers and downstream protective devices.
The E1.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 400 V AC. The WMP configuration is a four-pole withdrawable moving part fitted with four auxiliary changeover contacts and open/closed breaker position indication, and it connects to the main circuit through a compatible separate Emax 2 E1.2 fixed part.
