1SDA072229R1 ABB E1.2C 1600 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker

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

The ABB E1.2C 1600 Ekip Hi-Touch LSIG 3p WMP, order code 1SDA072229R1, is a high-performance three-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range, designed for advanced protection and switching in demanding low-voltage electrical distribution systems. Rated at 1600 A, it combines the compact E1.2C frame with the sophisticated Ekip Hi-Touch LSIG electronic trip unit for comprehensive protection, measurement and power-system supervision.

The Ekip Hi-Touch LSIG release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and ground-fault protection. Its advanced electronic platform extends the capabilities of the Emax 2 breaker beyond basic circuit protection, supporting detailed electrical measurements, configurable protection functions and integration into modern power management architectures.

This version is a three-pole withdrawable moving part with a 1600 A rated uninterrupted current and a rated operational voltage of 690 V AC. The E1.2C performance class provides an ultimate short-circuit breaking capacity of 50 kA at 400–440 V AC and 42 kA at 690 V AC, making it suitable for industrial plants, critical infrastructure and high-performance distribution switchboards.
