1SDA072230R1 ABB E1.2C 1600 Ekip G Hi-Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E1.2C 1600 Ekip G Hi-Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E1.2C 1600 Ekip G Hi-Touch LSIG 3p WMP, order code 1SDA072230R1, is a high-performance three-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range, designed for generator protection and demanding low-voltage power distribution applications. Rated at 1600 A, it combines the compact E1.2C frame with the advanced Ekip G Hi-Touch LSIG electronic trip unit for comprehensive protection, measurement and generator-oriented power management.

The Ekip G Hi-Touch release provides advanced protection functions tailored to generator and power-generation applications. Its LSIG functionality includes long-time overload, short-time delayed short-circuit, instantaneous short-circuit and ground-fault protection, helping safeguard generators, conductors, switchgear and connected equipment while supporting selective coordination throughout the electrical network.

This version is a three-pole withdrawable moving part with a 1600 A rated uninterrupted current. The E1.2C performance class provides a rated ultimate short-circuit breaking capacity of 50 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s, making it a robust solution for generator switchboards, industrial power systems and critical electrical infrastructure.
