Why Choose the ABB 1SDA072657R1 Emax 2 E6.2V 6300 Air Circuit Breaker?

The ABB 1SDA072657R1 is a high-performance SACE Emax 2 E6.2V air circuit breaker designed for protection, control and management of demanding low-voltage electrical distribution and generator systems. Configured as the E6.2V 6300 Ekip G Touch LSIG 3p WMP, this three-pole withdrawable moving part combines a 6300 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 long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. The Ekip G Touch release is designed for applications requiring advanced generator protection together with sophisticated measurement, monitoring and power-system management capabilities.

The E6.2V 6300 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, 130 kA at 500 V AC and 100 kA at 690 V AC. Its withdrawable construction facilitates inspection and maintenance in compatible switchboards, while the moving part is designed for connection to the corresponding Emax 2 fixed part.

Advanced Generator and High-Current Distribution Protection

Air circuit breakers such as the ABB SACE Emax 2 E6.2V provide switching and protection for high-current low-voltage distribution networks. The electronic protection release continuously monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect generators, conductors and connected electrical equipment against damaging fault conditions.

The Ekip G Touch LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection functions. Combined with the E6.2V breaker's high interruption capability and withdrawable architecture, this configuration is particularly suited to generator installations and sophisticated power-distribution switchboards where advanced protection, selectivity and maintainability are required.

Typical Applications

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