1SDA072645R1 ABB E6.2H 6300 Ekip Touch LSI 3p WMP Air Circuit Breaker 6300 A

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

The ABB E6.2H 6300 Ekip Touch LSI 3p WMP, order code 1SDA072645R1, 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 LSI electronic trip unit, it provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit 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 up to 100 kA, while the 690 V AC rated operational voltage makes it suitable for a broad range of industrial, infrastructure and large-scale commercial distribution systems.

The 1SDA072645R1 is the moving part of a withdrawable circuit breaker, designed for installation with the appropriate fixed part in compatible ABB SACE Emax 2 switchgear. Its Ekip Touch LSI release combines configurable electronic protection with an intuitive touchscreen interface, supporting protection coordination, system supervision and efficient operation of critical high-current distribution circuits.

Selective 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 short-circuit breaking performance of up to 100 kA, making it particularly suitable for major incoming and distribution circuits where substantial load currents and high prospective fault levels must be safely managed.

The Ekip Touch LSI electronic trip unit provides long-time overload (L), short-time delayed short-circuit (S) and instantaneous short-circuit (I) protection. The short-time function supports selective coordination between circuit breakers, while the touchscreen interface facilitates interaction with protection settings and operating information. Combined with the withdrawable E6.2 construction, this makes the 1SDA072645R1 well suited to critical switchgear installations requiring high current capacity, protection flexibility and serviceability.
