1SDA072659R1 ABB E6.2V 6300 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker 6300 A

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

The ABB E6.2V 6300 Ekip Hi-Touch LSIG 3p WMP, order code 1SDA072659R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, engineered for advanced protection, switching, measurement and monitoring in demanding low-voltage power distribution systems. With a 6300 A rated uninterrupted current and ABB's advanced Ekip Hi-Touch LSIG electronic trip unit, it provides long-time, short-time, instantaneous and earth-fault protection.

The E6.2V is designed for high-power electrical networks with exceptionally high prospective fault currents. Its V-performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 s, making it particularly suitable for major industrial, infrastructure and critical power distribution systems.

The 1SDA072659R1 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 supplied with four auxiliary contacts and circuit-breaker open/closed position indication, while the Ekip Hi-Touch platform combines comprehensive LSIG protection with advanced measurement and monitoring functionality.

Advanced LSIG Protection for High-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 E6.2V combines a substantial 6300 A current rating with a 150 kA ultimate short-circuit breaking capacity at 440 V AC and 100 kA short-time withstand current for 1 s, making it suitable for major incoming and distribution circuits where exceptionally high prospective fault currents must be safely managed.

The Ekip Hi-Touch LSIG electronic trip unit provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. Combined with advanced measurement and monitoring capabilities, the Hi-Touch platform supports sophisticated protection coordination and electrical system supervision, while the withdrawable E6.2 construction facilitates servicing within critical high-current switchgear.

Typical Applications

• Main low-voltage electrical switchboards.
• Heavy industrial power distribution systems.
• Manufacturing and process plant switchgear.
