1SDA072436R1 ABB E2.2H 2500 Ekip Touch LSIG 3p WMP Air Circuit Breaker 2500 A

Why Choose the ABB E2.2H 2500 Ekip Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2H 2500 Ekip Touch LSIG 3p WMP, order code 1SDA072436R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. With a 2500 A rated current and ABB's advanced Ekip Touch LSIG electronic trip unit, it provides comprehensive long-time, short-time, instantaneous and earth-fault protection.

The E2.2H combines high current-carrying capability with high short-circuit performance for industrial and commercial power distribution. This H-performance model provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC, making it suitable for installations with high prospective fault currents and demanding protection requirements.

The 1SDA072436R1 is the moving part of a withdrawable circuit breaker and features a three-pole configuration. It has a rated operational voltage of up to 690 V AC, a rated insulation voltage of 1000 V AC and a rated impulse withstand voltage of 12 kV. Its Ekip Touch LSIG release adds earth-fault protection to the long-time, short-time and instantaneous functions, providing comprehensive electronic protection for critical electrical distribution systems.

Advanced Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and circuit protection in high-current low-voltage electrical networks. The E2.2H performance level is designed for installations requiring particularly high short-circuit interruption capability, helping protect electrical equipment and distribution infrastructure against potentially damaging fault currents.

The Ekip Touch LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Combined with the withdrawable construction and high breaking capacity of the E2.2H, this makes the 1SDA072436R1 particularly suitable for sophisticated distribution systems where protection coordination, selectivity, earth-fault detection, serviceability and dependable operation are important.
