1SDA072655R1 ABB E6.2V 6300 Ekip Touch LSI 3P WMP Air Circuit Breaker

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

The ABB 1SDA072655R1 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 LSI electronic trip unit for precise protection against overload, short-circuit and instantaneous fault conditions.

As part of the ABB SACE Emax 2 range, the E6.2V 6300 is engineered for demanding industrial and infrastructure switchboards where high current capacity and high 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, while the breaker has a rated operational voltage of up to 690 V AC.

This model is supplied in a three-pole withdrawable moving-part (WMP) configuration. Its Ekip Touch LSI release provides Long-time, Short-time and Instantaneous protection functions through an intuitive electronic protection platform, supporting accurate circuit protection and easier management of critical low-voltage distribution installations.

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 overcurrents and short circuits. The Ekip Touch LSI electronic release continuously monitors electrical conditions and provides configurable Long-time, Short-time and Instantaneous protection functions to coordinate 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 its fixed section, supporting inspection, servicing and replacement in installations where maintainability is 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.
