1SDA073151R1 ABB E4.2V 3200 Ekip Dip LI 4p WMP Air Circuit Breaker 3200 A

Why Choose the ABB E4.2V 3200 Ekip Dip LI 4p WMP Air Circuit Breaker?

The ABB E4.2V 3200 Ekip Dip LI 4p WMP, order code 1SDA073151R1, is a high-performance four-pole air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 3200 A, it is engineered for demanding low-voltage power distribution systems where very high short-circuit interruption capability, reliable electronic protection and service-friendly withdrawable construction are required.

This E4.2V breaker incorporates an Ekip Dip LI solid-state electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. The overload protection range is adjustable from 1280–3200 A, while the instantaneous short-circuit release can be set from 4800–48,000 A, allowing the protection characteristics to be coordinated with the connected electrical system.

The V performance level provides exceptional fault interruption capability, including a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC. The WMP configuration is the moving part of a withdrawable Emax 2 breaker system and connects through a separate fixed chassis, supporting efficient inspection, maintenance and replacement in high-availability switchboards.

High-Performance LI Protection for Critical Power Distribution

The ABB E4.2V 3200 combines a high 3200 A current rating with the Ekip Dip LI electronic release to protect low-voltage distribution circuits against sustained overloads and severe short circuits. Adjustable long-time and instantaneous thresholds allow the breaker response to be matched to the requirements of the installation while retaining straightforward DIP-switch configuration.

With a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, the E4.2V is particularly suitable for installations with very high prospective fault currents. Its withdrawable architecture allows the moving breaker section to be separated from its compatible fixed chassis for maintenance, helping reduce disruption in critical industrial and infrastructure switchboards.

Typical Applications

• Main incoming protection for high-current low-voltage switchboards.
• Industrial power distribution systems.
• High-fault-level feeder and distribution protection.
• Manufacturing and process plants.
