1SDA073104R1 ABB E4.2V 2500 Ekip Touch LI 4p WMP Air Circuit Breaker

Why Choose the ABB E4.2V 2500 Ekip Touch LI 4p WMP Air Circuit Breaker?

The ABB E4.2V 2500 Ekip Touch LI 4p WMP, order code 1SDA073104R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. Rated at 2500 A, this withdrawable moving part combines the E4.2 frame and high-breaking-capacity V performance level with an advanced Ekip Touch LI electronic trip unit.

The Ekip Touch LI release provides long-time overload (L) and instantaneous short-circuit (I) protection. Its touchscreen interface enables straightforward configuration of protection settings, with overload protection adjustable from 0.4–1 × In and instantaneous protection adjustable from 1.5–15 × In, making the breaker suitable for high-current distribution circuits requiring dependable electronic protection.

With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and an ultimate short-circuit breaking capacity of 150 kA at 380–440 V AC, the E4.2V 2500 is engineered for electrical networks with very high prospective fault currents. Its four-pole withdrawable moving-part construction supports efficient inspection and maintenance when installed with the corresponding ABB Emax 2 fixed chassis.
