1SDA072101R1 ABB E1.2C 800 Ekip Dip LI 3p WMP Air Circuit Breaker Moving Part

Why Choose the ABB E1.2C 800 Ekip Dip LI 3p WMP Air Circuit Breaker Moving Part?

The ABB E1.2C 800 Ekip Dip LI 3p WMP, order code 1SDA072101R1, is the three-pole moving part of a withdrawable SACE Emax 2 air circuit breaker, engineered for protection and switching in low-voltage power distribution systems. Rated at 800 A, this E1.2C assembly combines ABB's compact withdrawable Emax 2 architecture with reliable Ekip Dip electronic protection.

The breaker is equipped with an Ekip Dip LI electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. This protection configuration is suited to distribution circuits requiring dependable overload protection together with rapid interruption of severe short-circuit faults.

As a WMP moving part, the 1SDA072101R1 is designed to operate 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 400–440 V AC and 42 kA at 500–690 V AC, together with a rated short-time withstand current of 42 kA for 1 s.

Reliable LI Protection for Withdrawable Power Distribution

Withdrawable air circuit breakers allow the active breaker assembly to be separated from its fixed chassis, making inspection, maintenance and replacement easier while permanent switchboard connections remain in place. The ABB Emax 2 E1.2 platform combines this service-friendly architecture with compact dimensions and strong short-circuit performance for modern low-voltage distribution systems.

The Ekip Dip LI electronic release protects the circuit against sustained overloads and severe instantaneous short-circuit faults. Combined with the E1.2C frame's 50 kA ultimate breaking capacity at 400–440 V AC and 42 kA short-time withstand capability for 1 s, the 1SDA072101R1 provides dependable protection for appropriately coordinated electrical distribution networks.

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 circuits requiring electronic overload and instantaneous short-circuit protection.
