1SDA073135R1 ABB E4.2S 3200 Ekip Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E4.2S 3200 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E4.2S 3200 Ekip Touch LSI 4p WMP, order code 1SDA073135R1, is a high-performance four-pole air circuit breaker moving part designed for protection, control and monitoring in demanding low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, it combines a 3200 A rated uninterrupted current with the intelligent Ekip Touch LSI electronic trip unit.

The Ekip Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Its touch-sensitive display enables straightforward configuration of protection parameters, while adjustable electronic protection supports effective selectivity and coordination throughout industrial, commercial and infrastructure electrical networks.

This E4.2S configuration features a 3200 A rated uninterrupted current, four-pole construction and a rated operational voltage up to 690 V AC. The S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 400/415/440 V AC and 66 kA at 500–690 V AC, while the withdrawable moving-part construction supports efficient inspection and maintenance.

Advanced LSI Protection for High-Current Distribution

The ABB Ekip Touch LSI electronic trip unit provides adjustable protection against overload and both delayed and instantaneous short-circuit conditions. Long-time protection safeguards conductors and equipment against sustained overcurrent, while short-time and instantaneous functions enable coordinated interruption of higher fault currents within the distribution network.

The E4.2S frame is engineered for high-current installations requiring dependable fault interruption, selectivity and continuity of service. Its combination of 85 kA breaking capacity at 400/415/440 V AC, 66 kA short-time withstand capability and withdrawable construction makes it well suited to maintainable industrial and infrastructure switchboards.

Typical Applications

• High-current industrial power distribution switchboards.
• Main incoming and outgoing feeder protection.
• Transformer secondary distribution systems.
• Manufacturing and process industry installations.
• Data centres and critical power infrastructure.
• Commercial buildings and large infrastructure projects.
• Utility and energy distribution installations.
• Low-voltage networks requiring selective electronic short-circuit protection.
