1SDA072455R1 ABB E4.2V 2000 Ekip Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E4.2V 2000 Ekip Touch LSI 3p WMP Air Circuit Breaker?

The ABB E4.2V 2000 Ekip Touch LSI 3p WMP, order code 1SDA072455R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for protection and control in demanding low-voltage power distribution systems. As part of the advanced ABB Emax 2 series, this three-pole circuit breaker combines a rated current of 2000 A with the intelligent Ekip Touch LSI electronic trip unit for configurable overload and short-circuit protection.

The E4.2V performance level is engineered for installations requiring exceptionally high fault interruption capability. Its Ekip Touch LSI electronic release provides long-time, short-time and instantaneous protection functions, helping protect electrical installations against overloads and short circuits while allowing effective protection coordination within complex distribution networks.

With a rated current of 2000 A, a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a short-time withstand current of 100 kA for 1 s, the 1SDA072455R1 is designed for substantial industrial, infrastructure and commercial power distribution systems. Its three-pole withdrawable moving-part configuration facilitates inspection, servicing and maintenance within compatible ABB SACE Emax 2 switchgear.

Advanced LSI Protection for High-Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage electrical systems against overload and short-circuit conditions. The E4.2V platform provides exceptionally high fault interruption capability, making it particularly suitable for main distribution boards and installations where prospective short-circuit currents can be substantial.

The Ekip Touch LSI electronic trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Combined with the E4.2V breaker’s high breaking and short-time withstand capabilities, this allows effective protection and selectivity within sophisticated industrial and commercial electrical distribution systems.

Typical Applications

• Main low-voltage electrical distribution boards.
• High-power industrial switchboards.
• Transformer secondary and distribution protection.
• Manufacturing and process plant electrical systems.
• Data centres and critical infrastructure power distribution.
• Commercial and infrastructure installations with high prospective fault currents.
