Why Choose the ABB E1.2B 630 Ekip Dip LI 3p WMP Air Circuit Breaker Moving Part?
The ABB E1.2B 630 Ekip Dip LI 3p WMP, order code 1SDA072051R1, 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 E1.2B unit combines compact Emax 2 construction with ABB's Ekip Dip LI solid-state electronic protection.
The moving part is equipped with an Ekip Dip LI electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. This protection combination is suited to distribution circuits requiring dependable overload and high-current fault protection without the additional short-time or ground-fault functions of LSI and LSIG releases.
As the WMP moving portion of a withdrawable Emax 2 breaker, the 1SDA072051R1 is intended for use with the corresponding fixed part rather than as a complete fixed circuit breaker. The E1.2B 630 platform provides a rated ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s.
Key Advantages
- 630 A three-pole Emax 2 moving part for withdrawable air circuit breaker installations.
- Ekip Dip LI solid-state release provides overload and instantaneous short-circuit protection.

Reliable Withdrawable Protection for Power Distribution
Withdrawable air circuit breakers allow the active breaker assembly to be removed from its fixed cradle, supporting inspection, maintenance and replacement while retaining the installed switchboard connection structure. The ABB E1.2 platform brings this flexibility to compact low-voltage distribution systems where dependable protection and serviceability are important.
The Ekip Dip LI release protects the circuit against sustained overloads and severe short-circuit currents through its long-time and instantaneous protection functions. Combined with the E1.2B frame's 42 kA breaking and short-time withstand performance at the specified ratings, the 1SDA072051R1 provides a robust moving breaker assembly for appropriately coordinated Emax 2 withdrawable installations.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process control switchboards.
- Incoming and feeder circuit protection.
- Withdrawable switchgear requiring convenient breaker servicing.
- Distribution circuits requiring overload and instantaneous short-circuit protection.
