1SDA072326R1 ABB E2.2H 1250 Ekip Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 1250 Ekip Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2H 1250 Ekip Touch LSIG 3p WMP, order code 1SDA072326R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for comprehensive protection and control of demanding low-voltage electrical distribution systems. Combining the E2.2H frame with a 1250 A rated uninterrupted current and Ekip Touch LSIG electronic trip unit, it provides advanced overload, short-circuit and earth-fault protection for industrial, commercial and infrastructure power networks.

The Ekip Touch LSIG solid-state electronic release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. Adjustable protection thresholds allow the breaker to be coordinated with other protective devices throughout the network, while the Ekip Touch interface provides convenient access to protection settings and operating information.

The E2.2H performance level delivers a rated ultimate short-circuit breaking capacity of 100 kA at 400/415 V AC and 85 kA at 500–690 V AC, with a rated short-time withstand current of 85 kA for 1 s. This three-pole WMP version is supplied as a withdrawable moving part and includes four auxiliary changeover contacts plus circuit-breaker open/closed position indication.

Comprehensive LSIG Protection for High-Fault-Level Networks

ABB SACE Emax 2 air circuit breakers are engineered to protect low-voltage electrical networks where high current capacity, selective coordination and dependable fault interruption are essential. The E2.2H performance level offers particularly high short-circuit breaking capability, making it suitable for main distribution boards, industrial switchgear and installations with substantial prospective fault currents.

The Ekip Touch LSIG trip unit combines long-time overload protection with short-time delayed, instantaneous and earth-fault protection. Together with the breaker’s high short-time withstand capability, these functions allow engineers to develop coordinated protection strategies that isolate faults close to their source while helping maintain continuity of supply to unaffected sections of the electrical system.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Main incoming electrical supplies.
• Manufacturing and process plants.
• Commercial and infrastructure electrical distribution.
• Installations with high prospective short-circuit currents.
• Electrical systems requiring comprehensive LSIG protection and selective coordination.
