1SDA072561R1 ABB E4.2H 4000 Ekip Dip LI 3p WMP Air Circuit Breaker

Why Choose the ABB E4.2H 4000 Ekip Dip LI 3p WMP Air Circuit Breaker?

The ABB E4.2H 4000 Ekip Dip LI 3p WMP, order code 1SDA072561R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and control of demanding low-voltage electrical distribution systems. As part of the advanced ABB SACE Emax 2 E4.2 series, this three-pole withdrawable breaker combines a 4000 A rated uninterrupted current with the reliable Ekip Dip LI electronic trip unit.

The Ekip Dip LI solid-state release provides long-time overload and instantaneous short-circuit protection, delivering dependable protection for cables, busbars, transformers and other distribution equipment. Its adjustable protection settings allow the breaker to be coordinated with high-current industrial and infrastructure networks while maintaining straightforward operation.

The E4.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 415 V AC and 85 kA at 690 V AC. This WMP configuration is the withdrawable moving part and is fitted with four auxiliary changeover contacts and circuit-breaker open/closed position indication, while the compatible Emax 2 E4.2 fixed part is installed separately.
