Why Choose the ABB E1.2B 630 Ekip Dip LSI 3p WMP Air Circuit Breaker Moving Part?
The ABB E1.2B 630 Ekip Dip LSI 3p WMP, order code 1SDA072052R1, is the three-pole moving part of a withdrawable SACE Emax 2 air circuit breaker, designed for protection and switching in low-voltage power distribution systems. Rated at 630 A, this compact E1.2B assembly combines ABB's withdrawable Emax 2 architecture with an Ekip Dip LSI electronic trip unit.
The Ekip Dip LSI release provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. Adjustable protection settings allow the breaker to be coordinated with other protective devices in the distribution network, while the absence of integrated ground-fault protection makes this LSI version suitable where earth-fault protection is provided separately or is not required at the breaker.
As a WMP moving part, the 1SDA072052R1 is designed for use with the corresponding Emax 2 fixed part or cradle. The E1.2B platform provides a rated ultimate short-circuit breaking capacity of 42 kA at 400–690 V AC and a rated short-time withstand current of 42 kA for 1 s, supporting dependable protection in industrial and commercial distribution switchboards.

Reliable LSI Protection for Withdrawable Power Distribution
Withdrawable air circuit breakers allow the active breaker assembly to be removed from its fixed cradle, providing practical advantages for maintenance, inspection and replacement in electrical switchboards. The ABB Emax 2 E1.2 platform combines this service-friendly architecture with compact construction and dependable high-current switching performance.
The Ekip Dip LSI release protects the circuit against sustained overloads and both delayed and instantaneous short-circuit conditions. Its adjustable long-time, short-time and instantaneous settings allow protection to be coordinated with other devices in the electrical network, helping maintain selectivity while providing rapid interruption of severe faults.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchboards.
- Transformer and installation protection.
- Incoming and feeder circuit protection.
- Withdrawable switchgear requiring convenient breaker servicing.
- Distribution networks requiring adjustable LSI overcurrent protection.
