1SDA072626R1 ABB E6.2V 5000 Ekip Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E6.2V 5000 Ekip Touch LSIG 3p WMP Air Circuit Breaker?

The ABB 1SDA072626R1 is a high-performance SACE Emax 2 E6.2V air circuit breaker (ACB) designed for advanced protection and control of demanding low-voltage electrical distribution systems. Rated at 5000 A, this three-pole breaker combines ABB’s high-breaking-capacity E6.2V frame with an Ekip Touch LSIG electronic trip unit for comprehensive overload, short-circuit and earth-fault protection.

As part of the advanced ABB SACE Emax 2 air circuit breaker series, the E6.2V is designed for high-current industrial switchboards, data centres, critical infrastructure and major power distribution installations. The Ekip Touch trip unit combines electronic protection with an intuitive touchscreen interface, while the modular Emax 2 platform supports advanced measurement, monitoring, communication and power-management functions.

The 1SDA072626R1 is a three-pole withdrawable mobile part (WMP) with a rated uninterrupted current of 5000 A and rated operational voltage of 690 V AC. The E6.2V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, making this breaker particularly suitable for large electrical networks with exceptionally high prospective fault currents.
