1SDA072523R1 ABB E4.2V 3200 Ekip Dip LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E4.2V 3200 Ekip Dip LSIG 3p WMP Air Circuit Breaker?

The ABB E4.2V 3200 Ekip Dip LSIG 3p WMP, order code 1SDA072523R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and control of demanding low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 E4.2 series, this three-pole withdrawable breaker combines a 3200 A rated uninterrupted current with an Ekip Dip LSIG solid-state electronic trip unit.

The Ekip Dip LSIG release provides comprehensive circuit protection with long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault functions. Its adjustable protection settings allow the breaker to be coordinated with the requirements of industrial switchboards, transformer distribution systems, generator installations and other high-current electrical networks.

The E4.2V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 415 V AC and 100 kA at 690 V AC. This WMP configuration is a withdrawable moving part for installation with a compatible Emax 2 E4.2 fixed part, supporting efficient switchboard servicing, inspection and replacement.

High-Performance Circuit Protection for Power Distribution

ABB SACE Emax 2 air circuit breakers are engineered to protect low-voltage electrical networks against overloads, short circuits and earth faults. The E4.2V performance level combines a high continuous-current rating with exceptional short-circuit interruption capability, making it suitable for installations where network fault levels demand particularly robust protection.

The Ekip Dip LSIG trip unit provides adjustable electronic protection without unnecessary complexity. Long-time, short-time, instantaneous and earth-fault functions allow the breaker to protect cables, busbars, transformers, generators and downstream equipment while supporting selective coordination within sophisticated electrical distribution systems.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• Transformer and generator protection systems.
• Power distribution centres and electrical substations.
• Manufacturing and process-industry installations.
• Data centres and critical power infrastructure.
• Large commercial and infrastructure electrical systems.
• High-fault-level switchboards requiring withdrawable circuit breakers.
