1SDA072261R1 ABB E2.2H 800 Ekip Dip LI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 800 Ekip Dip LI 3p WMP Air Circuit Breaker?

The ABB E2.2H 800 Ekip Dip LI 3p WMP, order code 1SDA072261R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for reliable protection and control of low-voltage electrical distribution systems. Combining the robust E2.2H frame with an 800 A rated current and Ekip Dip LI electronic trip unit, it provides dependable overload and instantaneous short-circuit protection for demanding industrial and commercial power installations.

The E2.2H high-breaking-capacity version is engineered for electrical systems where substantial fault currents may occur. With a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a rated short-time withstand current of 85 kA for 1 s, it provides robust protection for main distribution boards and other critical low-voltage switchgear.

This three-pole version is supplied as a withdrawable moving part (WMP), allowing the circuit breaker to be removed from a compatible Emax 2 fixed part for inspection, servicing or replacement. The withdrawable format is particularly suited to installations where maintainability, continuity of service and efficient switchboard management are important.
