1SDA073128R1 ABB E4.2N 3200 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E4.2N 3200 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker?

The ABB E4.2N 3200 Ekip Hi-Touch LSI 4p WMP, order code 1SDA073128R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for advanced protection, measurement and switching in high-current low-voltage power distribution systems. Rated at 3200 A, this withdrawable moving part combines the E4.2N breaker platform with an advanced Ekip Hi-Touch LSI electronic trip unit.

The Ekip Hi-Touch LSI release provides long-time overload (L), short-time selective short-circuit (S) and instantaneous short-circuit (I) protection. Its advanced touchscreen interface supports intuitive configuration and monitoring, while the Hi-Touch platform provides enhanced measurement and power-quality capabilities for sophisticated industrial and infrastructure electrical networks.

With a rated operational voltage of 690 V AC and a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC, the E4.2N 3200 provides dependable protection for high-current distribution systems. Its four-pole withdrawable moving-part construction allows connection through a separate Emax 2 fixed chassis, supporting efficient maintenance, inspection and replacement within electrical switchboards.
