1SDA071293R1 ABB E6.2H 6300 Ekip Dip LSIG 3p F HR Air Circuit Breaker

Why Choose the ABB E6.2H 6300 Ekip Dip LSIG 3p F HR Air Circuit Breaker?

The ABB E6.2H 6300 Ekip Dip LSIG 3p F HR, order code 1SDA071293R1, is a high-current Emax 2 air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, it combines a substantial 6300 A rated uninterrupted current with the E6.2 frame and H short-circuit performance level for industrial, infrastructure and critical power applications.

This fixed three-pole circuit breaker incorporates the Ekip Dip LSIG solid-state electronic trip unit, providing long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection. The comprehensive LSIG protection package supports selective coordination while adding integrated earth-fault protection for installations requiring broader fault coverage.

With a rated operational voltage of 690 V AC, the E6.2H 6300 provides an ultimate short-circuit breaking capacity of 100 kA across 400–690 V AC and a rated short-time withstand current of 100 kA for both 1 s and 3 s. Its fixed three-pole construction and rear flat horizontal terminals provide a robust solution for integration into very high-current low-voltage switchboards.

6300 A LSIG Protection for High-Current Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H provide switching, isolation and electronic protection at major distribution points in high-current low-voltage systems. With a rated uninterrupted current of 6300 A, 100 kA ultimate short-circuit breaking capacity across 400–690 V AC and 100 kA short-time withstand capability for both 1 s and 3 s, this configuration is designed for substantial loads and high prospective fault levels.

The Ekip Dip LSIG trip unit combines long-time overload protection with selective short-time, instantaneous short-circuit and earth-fault protection. The selective short-time function can assist coordination with downstream protective devices, while integrated earth-fault protection provides additional coverage against faults involving earth, making this breaker suitable for sophisticated high-current distribution architectures.

Typical Applications

• Main low-voltage switchboards and very high-current distribution boards.
• High-current industrial electrical distribution systems.
• Transformer secondary and main incomer protection.
• Manufacturing and process facilities.
• Data centres and critical power infrastructure.
• Large commercial and infrastructure installations.
• High-current feeder protection.
• Electrical systems requiring selective LSIG protection with integrated earth-fault functionality.
