1SDA072656R1 ABB E6.2V 6300 Ekip Touch LSIG 3P WMP Air Circuit Breaker

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

The ABB 1SDA072656R1 is a high-performance SACE Emax 2 E6.2V air circuit breaker designed for protection and control of high-current low-voltage electrical distribution systems. Rated at 6300 A, this three-pole breaker combines ABB's E6.2 frame with the advanced Ekip Touch LSIG electronic trip unit for comprehensive protection against overload, short-circuit, instantaneous and earth-fault conditions.

As part of the ABB SACE Emax 2 range, the E6.2V 6300 is engineered for demanding industrial, infrastructure and critical-power switchboards where high current capacity and substantial short-circuit performance are required. The V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, making it suitable for installations with high prospective fault currents.

This model is supplied in a three-pole withdrawable moving-part (WMP) configuration. Its Ekip Touch LSIG release provides Long-time, Short-time, Instantaneous and Ground-fault protection functions through ABB's advanced electronic protection platform, enabling accurate protection and coordination within complex low-voltage power distribution networks.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2 are designed to protect high-current electrical distribution circuits against damaging overloads, short circuits and other fault conditions. The Ekip Touch LSIG electronic release continuously monitors electrical conditions and provides configurable Long-time, Short-time, Instantaneous and Ground-fault protection functions for coordinated protection across complex low-voltage networks.

The E6.2V platform combines a 6300 A current rating with high short-circuit interruption capability, making this breaker particularly suitable for main incoming and distribution duties in large switchboards. Its withdrawable construction also allows the breaker moving part to be isolated and removed from the corresponding fixed part, supporting inspection, servicing and replacement in installations where maintainability and continuity are important.

Typical Applications

• Main incoming protection for high-current low-voltage switchboards.
• Industrial power distribution and process plants.
• Large commercial and infrastructure electrical systems.
• Power generation and utility distribution installations.
• Data centre and critical-power switchboards.
• Large manufacturing facilities and automated production plants.
• Transformer secondary and main distribution protection.
• High-fault-level low-voltage distribution networks.
