Why Choose the ABB E1.2C 800 Ekip Dip LSI 3p WMP Air Circuit Breaker Moving Part?
The ABB E1.2C 800 Ekip Dip LSI 3p WMP, order code 1SDA072102R1, is the three-pole moving part of a withdrawable SACE Emax 2 air circuit breaker, engineered for protection and switching in demanding low-voltage power distribution systems. Rated at 800 A, this E1.2C assembly combines ABB's compact withdrawable Emax 2 architecture with an Ekip Dip solid-state electronic protection release.
The breaker is equipped with an Ekip Dip LSI electronic trip unit, providing long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. The addition of adjustable short-time protection makes the LSI configuration particularly useful in distribution systems where selective coordination between upstream and downstream protective devices is required.
As a WMP moving part, the 1SDA072102R1 is designed for use with the corresponding Emax 2 fixed part or cradle. The E1.2C performance level provides a rated ultimate short-circuit breaking capacity of 50 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s, providing dependable protection for industrial, commercial and infrastructure switchboards.

Selective LSI Protection for Withdrawable Power Distribution
Withdrawable air circuit breakers allow the active breaker assembly to be separated from its fixed chassis, simplifying inspection, maintenance and replacement while permanent switchboard connections remain installed. The ABB Emax 2 E1.2 platform combines this service-friendly architecture with compact construction and strong short-circuit performance for modern low-voltage distribution systems.
The Ekip Dip LSI release protects against sustained overloads, delayed short-circuit conditions and severe instantaneous faults. Its combination of L, S and I protection functions supports coordinated tripping within multi-level distribution networks, while the E1.2C frame's 50 kA breaking capacity and 42 kA short-time withstand capability provide robust performance under high fault-current conditions.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchboards.
- Transformer secondary distribution systems.
- Incoming and feeder circuit protection.
- Withdrawable switchgear requiring convenient breaker servicing.
- Distribution networks requiring adjustable LSI overcurrent protection.
- Systems requiring coordinated short-time and instantaneous fault protection.
