1SDA073213R1 ABB E6.2H 4000 Ekip Dip LSIG 4p WMP Air Circuit Breaker 4000 A

Why Choose the ABB E6.2H 4000 Ekip Dip LSIG 4p WMP Air Circuit Breaker?

The ABB E6.2H 4000 Ekip Dip LSIG 4p WMP, order code 1SDA073213R1, is a high-performance four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 4000 A, it is designed for demanding low-voltage power-distribution systems requiring high short-circuit withstand capability, comprehensive electronic protection and service-friendly draw-out construction.

This E6.2H breaker incorporates an Ekip Dip LSIG solid-state electronic trip unit, providing long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. The Ekip Dip platform uses straightforward DIP-switch configuration, providing adjustable protection while maintaining a practical interface for switchboard commissioning and maintenance.

The E6.2H performance class provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC together with a rated short-time withstand current of 100 kA for 1 s. The WMP configuration is the moving part of a withdrawable Emax 2 breaker system and is designed for use with a compatible fixed part, enabling efficient inspection, servicing and replacement in critical high-current switchboards.

Comprehensive LSIG Protection for High-Current Power Distribution

The ABB E6.2H 4000 combines the high-current capabilities of the SACE Emax 2 E6.2 platform with the comprehensive protection functions of the Ekip Dip LSIG release. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection rapidly clears severe short circuits, and the G function provides dedicated earth-fault protection.

With a 4000 A current rating, 100 kA breaking capacity at 440 V AC and 100 kA short-time withstand current for 1 s, the E6.2H is engineered for demanding main-distribution and high-current feeder applications. Its withdrawable architecture enables the moving breaker section to be removed from its compatible fixed part for inspection, maintenance or replacement, supporting serviceability in critical power systems.

Typical Applications

• Main incoming protection for high-current low-voltage switchboards.
• Industrial power distribution and process plants.
• High-current feeder and busbar protection.
• Manufacturing facilities with high prospective fault levels.
