1SDA072019R1 ABB E6.2H/f 6300 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2H/f 6300 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2H/f 6300 Ekip Hi-Touch LSIG 4p FHR, order code 1SDA072019R1, is a high-performance Emax 2 air circuit breaker (ACB) designed for protection, switching and control of high-current low-voltage electrical distribution systems. As part of the advanced ABB SACE Emax 2 series, this fixed four-pole circuit breaker combines a 6300 A rated current with an Ekip Hi-Touch LSIG electronic trip unit for demanding industrial, commercial and infrastructure power distribution applications.

The E6.2H platform provides high short-circuit performance together with intelligent electronic protection, measurement and monitoring capabilities. Its Ekip Hi-Touch LSIG solid-state release provides long-time, short-time, instantaneous and ground-fault protection functions, helping protect electrical networks against overloads, short circuits and earth-fault conditions while supporting effective system selectivity.

With a rated uninterrupted current of 6300 A, a four-pole full-size neutral configuration and an ultimate short-circuit breaking capacity of 100 kA at 400 V AC, the E6.2H/f 6300 is suited to major incoming supplies, bus couplers and high-current feeders. Its fixed construction and rear flat horizontal terminals provide a robust connection arrangement for integration into high-capacity low-voltage switchboards.

Advanced Protection for High-Current Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H provide switching, isolation and protection for major circuits within low-voltage power distribution systems. The 6300 A rating makes this model particularly suitable for high-capacity incoming supplies, transformer secondaries, bus couplers and outgoing feeders where dependable interruption of substantial fault currents is essential for electrical safety and continuity of supply.

The Ekip Hi-Touch LSIG electronic trip unit provides comprehensive protection for complex electrical networks. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination, instantaneous protection provides rapid response to severe short circuits, and ground-fault protection adds protection against earth-fault conditions. These capabilities make the 1SDA072019R1 well suited to sophisticated power distribution systems requiring both high current capacity and advanced electronic protection.

Typical Applications

• Main low-voltage distribution switchboards.
• High-capacity industrial power distribution systems.
• Transformer secondary and incoming mains protection.
• High-current outgoing feeders.
• Bus coupler and switchboard applications.
• Manufacturing and process plants.
• Commercial and infrastructure electrical distribution.
• Data centres and critical power installations.
