1SDA073249R1 ABB E6.2H 5000 Ekip Hi-Touch LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2H 5000 Ekip Hi-Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E6.2H 5000 Ekip Hi-Touch LSIG 4p WMP, order code 1SDA073249R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, switching and advanced monitoring in demanding high-current low-voltage power distribution systems. Rated at 5000 A, this withdrawable moving part combines the E6.2 frame with ABB's H short-circuit performance level and an advanced Ekip Hi-Touch LSIG electronic trip unit.

The Ekip Hi-Touch LSIG release provides long-time overload (L), short-time selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. Its comprehensive electronic protection architecture supports selective coordination and protection of transformers, generators, main feeders and critical distribution assets, while the Hi-Touch platform provides advanced measurement and monitoring capabilities.

The E6.2H 5000 has a rated operational voltage of 690 V AC and provides an ultimate short-circuit breaking capacity of 100 kA at 400–690 V AC. Its service breaking capacity is 100% of Icu, while a rated short-time withstand current of 100 kA for both 1 s and 3 s provides strong support for selective protection in high-current distribution networks.

Advanced LSIG Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage electrical networks. The E6.2H platform combines a substantial 5000 A continuous-current rating with 100 kA ultimate short-circuit breaking capacity across the 400–690 V AC range, making it suitable for major incomers, bus couplers and high-current feeders.

The Ekip Hi-Touch LSIG trip unit combines long-time overload, delayed short-circuit, instantaneous short-circuit and earth-fault protection with advanced electronic monitoring capabilities. Together with the E6.2H breaker's 100 kA short-time withstand capability for up to 3 s, this configuration provides a strong platform for selective coordination and protection of critical electrical distribution assets.

Typical Applications

• Main low-voltage distribution switchboards.
• High-current industrial power distribution systems.
• Transformer and generator protection.
• Main incomer and high-current feeder protection.
• Bus coupler and bus-section applications.
• Manufacturing plants and process facilities.
