1SDA072141R1 ABB E1.2C 1000 Ekip Dip LI 3p WMP Air Circuit Breaker Moving Part

Why Choose the ABB E1.2C 1000 Ekip Dip LI 3p WMP Air Circuit Breaker Moving Part?

The ABB E1.2C 1000 Ekip Dip LI 3p WMP, order code 1SDA072141R1, is the three-pole moving part of a withdrawable SACE Emax 2 air circuit breaker, designed for reliable switching and protection in low-voltage power distribution systems. Rated at 1000 A, it combines the compact E1.2C breaker platform with ABB's Ekip Dip electronic protection technology.

The breaker is equipped with an Ekip Dip LI solid-state electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. The long-time protection setting covers 400–1000 A, while the instantaneous protection setting extends from 1500–15000 A, allowing the protection response to be matched to the characteristics of the distribution circuit.

As a WMP moving part, the 1SDA072141R1 is designed for use with the corresponding ABB Emax 2 fixed part or cradle, which is ordered separately. The E1.2C platform provides a rated ultimate short-circuit breaking capacity of 50 kA at 400–415 V AC and 42 kA at 690 V AC, providing robust fault interruption for industrial and commercial distribution systems.

Reliable LI Protection for Withdrawable Power Distribution

Withdrawable air circuit breakers allow the active breaker assembly to be separated from its fixed chassis, helping simplify inspection, servicing and replacement while permanent switchboard connections remain installed. The ABB Emax 2 E1.2 platform combines this service-friendly arrangement with compact construction and high short-circuit performance for modern low-voltage distribution systems.

The Ekip Dip LI release protects the circuit against sustained overloads and severe instantaneous short-circuit faults. Combined with the E1.2C frame's 50 kA breaking capacity at 400–415 V AC and operation at up to 690 V AC, the 1SDA072141R1 provides dependable protection for appropriately coordinated industrial and commercial electrical 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.
