1SDA072215R1 ABB E1.2B 1600 Ekip Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E1.2B 1600 Ekip Touch LSI 3p WMP Air Circuit Breaker?

The ABB E1.2B 1600 Ekip Touch LSI 3p WMP, order code 1SDA072215R1, is a high-performance three-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range, designed for reliable switching and protection in low-voltage electrical distribution systems. Rated at 1600 A, it combines the compact E1.2B frame with an advanced Ekip Touch LSI electronic trip unit for configurable overload and short-circuit protection.

The Ekip Touch protection release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Its touchscreen interface simplifies protection configuration and monitoring, helping engineers coordinate protection across industrial and commercial distribution networks while safeguarding conductors, switchgear and connected equipment.

This version is a three-pole withdrawable moving part with a 1600 A rated uninterrupted current and 690 V AC rated operational voltage. The E1.2B performance class provides a rated ultimate short-circuit breaking capacity of 42 kA across key low-voltage operating levels up to 690 V AC, while four change-over auxiliary contacts support circuit-breaker status signalling and control integration.
