1SDA073106R1 ABB E4.2V 2500 Ekip Touch LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E4.2V 2500 Ekip Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E4.2V 2500 Ekip Touch LSIG 4p WMP, order code 1SDA073106R1, is a high-performance four-pole air circuit breaker moving part designed for advanced protection, control and monitoring in demanding low-voltage power distribution systems. As part of the ABB SACE Emax 2 series, it combines a 2500 A rated uninterrupted current with the intelligent Ekip Touch LSIG solid-state electronic trip unit.

The Ekip Touch LSIG release provides comprehensive long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Its touchscreen interface supports intuitive protection configuration and electrical monitoring, while the adjustable protection functions enable effective coordination and selectivity throughout complex industrial and infrastructure distribution networks.

This E4.2V configuration features a 2500 A rated uninterrupted current, four-pole construction and a rated voltage of 690 V AC. The high-performance V breaking-capacity level provides an ultimate short-circuit breaking capacity of 150 kA at 400 V AC and a rated short-time withstand current of 100 kA for 1 s, while the withdrawable moving-part construction supports convenient servicing and maintenance.

Advanced LSIG Protection for High-Current Distribution

The ABB Ekip Touch LSIG electronic trip unit provides adjustable protection against the principal electrical faults encountered in low-voltage distribution systems. Long-time, short-time and instantaneous functions protect against overloads and short circuits, while integrated earth-fault protection adds protection against potentially damaging fault current flowing to earth.

The E4.2V frame is engineered for installations requiring exceptionally high fault-interruption performance. Its combination of 150 kA ultimate breaking capacity and 100 kA short-time withstand capability supports robust protection and selectivity, while the withdrawable construction allows the moving part to be removed from its corresponding fixed part for efficient maintenance and servicing.
