1SDA072646R1 ABB E6.2H 6300 Ekip Touch LSIG 3p WMP Air Circuit Breaker 6300 A

Why Choose the ABB E6.2H 6300 Ekip Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E6.2H 6300 Ekip Touch LSIG 3p WMP, order code 1SDA072646R1, is a high-capacity three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, switching and monitoring in demanding low-voltage power distribution systems. With a 6300 A rated uninterrupted current and ABB's advanced Ekip Touch LSIG electronic trip unit, it provides long-time, short-time, instantaneous and earth-fault protection.

The E6.2H is engineered for major high-current electrical networks where dependable fault interruption and selective protection are essential. Its H-performance level provides a rated ultimate short-circuit breaking capacity of 100 kA from 400–690 V AC, together with a rated short-time withstand current of 100 kA for 1 s, supporting demanding industrial and infrastructure distribution systems.

The 1SDA072646R1 is the moving part of a withdrawable circuit breaker, designed for installation with the appropriate fixed part in compatible ABB SACE Emax 2 switchgear. It is equipped with four auxiliary contacts and circuit-breaker open/closed position indication, while the Ekip Touch LSIG release combines configurable electronic protection with an intuitive touchscreen interface.

Selective LSIG Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and circuit protection for high-current low-voltage electrical networks. The E6.2H combines a substantial 6300 A current rating with a consistent 100 kA ultimate short-circuit breaking capacity from 400–690 V AC and 100 kA short-time withstand current for 1 s, making it suitable for major incoming and distribution circuits with demanding fault levels.

The Ekip Touch LSIG electronic trip unit provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. The combination supports comprehensive circuit protection and selective coordination, while the touchscreen interface facilitates interaction with protection settings and operating information. Combined with the withdrawable E6.2 construction, the 1SDA072646R1 provides a flexible solution for critical high-current switchgear.
