1SDA072221R1 ABB E1.2C 1600 Ekip Dip LI 3p WMP Air Circuit Breaker Moving Part

Why Choose the ABB E1.2C 1600 Ekip Dip LI 3p WMP Air Circuit Breaker Moving Part?

The ABB E1.2C 1600 Ekip Dip LI 3p WMP, order code 1SDA072221R1, is the three-pole moving part of a withdrawable SACE Emax 2 air circuit breaker, designed for dependable switching and protection of high-current low-voltage distribution systems. Rated at 1600 A, it combines the compact E1.2C frame with ABB's Ekip Dip electronic protection technology.

The Ekip Dip LI solid-state electronic trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection. Its adjustable protection characteristics allow the breaker to protect conductors and distribution equipment against sustained overloads while responding rapidly to severe short-circuit conditions.

As a WMP moving part, the 1SDA072221R1 connects through a corresponding Emax 2 withdrawable fixed chassis. The E1.2C performance class provides a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC, while the breaker is rated for operation up to 690 V AC, making it suitable for demanding industrial and commercial power-distribution applications.

Reliable LI Protection for High-Current Power Distribution

The ABB Emax 2 withdrawable architecture allows the active circuit-breaker assembly to be removed from its fixed chassis, supporting efficient inspection, servicing and replacement while the switchboard's permanent power connections remain associated with the fixed part. This makes the E1.2C platform well suited to installations where maintainability and continuity of service are important.

The Ekip Dip LI release provides focused protection against sustained overloads and severe instantaneous short-circuit faults. Combined with the E1.2C frame's 1600 A current rating, 690 V AC rated voltage and 50 kA ultimate breaking capacity at 400 V AC, the 1SDA072221R1 provides dependable protection for appropriately coordinated low-voltage power 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 high-current feeder protection.
• Data centres and critical electrical infrastructure.
• Withdrawable switchgear requiring service-friendly breaker construction.
• Distribution circuits requiring adjustable electronic LI protection.
