1SDA072627R1 ABB Emax 2 E6.2V 5000 Ekip G Touch LSIG 3-Pole Air Circuit Breaker

Why Choose the ABB 1SDA072627R1 Emax 2 E6.2V 5000 Air Circuit Breaker?

The ABB 1SDA072627R1 is a high-performance SACE Emax 2 E6.2V air circuit breaker designed for protection, control and management of demanding low-voltage electrical distribution systems. Configured as the E6.2V 5000 Ekip G Touch LSIG 3p WMP, this three-pole withdrawable moving part combines a 5000 A rated current with ABB's advanced Ekip G Touch electronic protection release.

As part of the ABB SACE Emax 2 range, this circuit breaker provides comprehensive LSIG protection functions covering overload, short-circuit and earth-fault protection. The Ekip G Touch release is specifically suited to applications requiring advanced generator and distribution protection, while the E6.2V performance level provides very high short-circuit interruption capability for critical power installations.

The E6.2V 5000 is rated for operation up to 690 V AC and provides an ultimate short-circuit breaking capacity of 150 kA at 400–415 V AC and 100 kA at 690 V AC. Its withdrawable construction facilitates inspection and maintenance in switchboards, while the moving part is designed for connection to the corresponding fixed part of the Emax 2 withdrawable system.

Advanced Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2V provide switching and protection for high-current low-voltage distribution networks. The breaker continuously works with its electronic trip unit to detect abnormal electrical conditions and disconnect the protected circuit when configured protection thresholds are exceeded.

The Ekip G Touch LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions, making this configuration particularly suitable for installations where selective protection and generator-related functionality are required. Its withdrawable architecture also allows the breaker moving part to be disconnected from the fixed switchboard section for servicing, testing or replacement.

Typical Applications

• High-current low-voltage main distribution switchboards.
• Generator protection and generator distribution systems.
• Industrial power distribution installations.
• Utility and infrastructure electrical distribution systems.
• Large manufacturing and process facilities.
• Critical power and energy-management switchboards.
