Why Choose the ABB E2.2S/E9 1250 Ekip Hi-Touch LSIG 3p FHR 900V?
The ABB E2.2S/E9 1250 Ekip Hi-Touch LSIG 3p FHR 900V, order code 1SDA104320R1, is a high-performance SACE Emax 2 air circuit breaker designed for protection and switching in demanding low-voltage AC power distribution systems. Built on the E2.2 frame, this fixed three-pole breaker combines a rated uninterrupted current of 1250 A with ABB's advanced Ekip Hi-Touch LSIG electronic protection release.
The Ekip Hi-Touch LSIG trip unit provides comprehensive electronic protection covering long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground or earth-fault (G) functions. Ekip Hi-Touch extends the Emax 2 protection platform with advanced protection, measurement and supervision capabilities for applications where detailed electrical system management is required.
This E2.2S/E9 configuration is designed for a rated voltage of 900 V AC and uses a fixed three-pole construction with horizontal rear terminals (FHR). The E2.2S performance level provides a rated ultimate short-circuit breaking capacity of 50 kA for this 900 V-class Emax 2 range, making the breaker suitable for demanding industrial, infrastructure and power distribution installations.
