1SDA070887R1 ABB E1.2N 1600 Ekip G Touch LSIG 3p F F Air Circuit Breaker

Why Choose the ABB E1.2N 1600 Ekip G Touch LSIG 3p F F Air Circuit Breaker?

The ABB E1.2N 1600 Ekip G Touch LSIG 3p F F, order code 1SDA070887R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, switching and isolation in demanding low-voltage electrical distribution systems. Rated at 1600 A, this three-pole fixed breaker combines the E1.2N frame with the advanced Ekip G Touch electronic release for industrial, commercial and infrastructure power networks.

The breaker incorporates the Ekip G Touch LSIG solid-state electronic trip unit, providing long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. The Ekip G Touch platform is specifically suited to advanced power-distribution and generator protection applications, combining configurable protection functions with an intuitive touch interface for effective system coordination and monitoring.

The 3p F F configuration identifies a three-pole fixed breaker with front terminals. The E1.2N frame provides a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC and a rated short-time withstand current of 50 kA for 1 s, making the 1SDA070887R1 suitable for main switchboards, incoming supplies and high-current distribution feeders.
