1SDA072658R1 ABB Emax 2 E6.2V 6300 Ekip Hi-Touch LSI 3-Pole Air Circuit Breaker

Why Choose the ABB 1SDA072658R1 Emax 2 E6.2V 6300 Air Circuit Breaker?

The ABB 1SDA072658R1 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 6300 Ekip Hi-Touch LSI 3p WMP, this three-pole withdrawable moving part combines a 6300 A rated current with ABB's advanced Ekip Hi-Touch electronic protection release.

As part of the ABB SACE Emax 2 range, this circuit breaker provides LSI protection functions covering long-time overload, short-time short-circuit and instantaneous short-circuit protection. The Ekip Hi-Touch release provides advanced protection, measurement and power-management capabilities for sophisticated industrial, infrastructure and critical-power distribution installations.

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 supports efficient inspection and maintenance within compatible switchboards, with the moving part designed for connection to the corresponding Emax 2 fixed part.

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 electronic protection release continuously monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect conductors, switchgear and connected electrical equipment against damaging overload and short-circuit conditions.

The Ekip Hi-Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Combined with the E6.2V breaker's high interruption capability, 6300 A current rating and withdrawable architecture, this configuration is well suited to sophisticated switchboards where advanced protection, operational flexibility and maintainability are important.

Typical Applications

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