1SDA104640R1 ABB E6.2H/E9 6300A Ekip Dip LSI 4P Air Circuit Breaker

Why Choose the ABB 1SDA104640R1 E6.2H/E9 Air Circuit Breaker?

The ABB 1SDA104640R1 is a high-performance SACE Emax 2 E6.2H/E9 air circuit breaker designed for protection and switching in demanding high-current low-voltage AC power distribution systems. Rated at 6300 A and 900 V AC, this four-pole breaker combines ABB's Emax 2 architecture with an Ekip Dip LSI electronic trip unit.

The Ekip Dip LSI release provides long-time, short-time and instantaneous protection, allowing the breaker to protect electrical installations against overload and short-circuit conditions. The E6.2H/E9 performance level provides a 75 kA breaking capacity at the specified 900 V AC system voltage, making this model suitable for substantial industrial and infrastructure power-distribution installations.

This four-pole withdrawable (WMP) configuration is particularly suited to switchboards where maintainability, isolation and continuity of service are important. As part of the ABB SACE Emax 2/E range, the breaker provides a robust platform for high-current electrical distribution while supporting the modular accessory and integration capabilities associated with the Emax 2 family.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2H/E9 form a critical protection and switching point in large electrical distribution systems. They monitor current through the installation and interrupt the circuit when overload or short-circuit conditions exceed the configured protection thresholds, helping safeguard switchboards, conductors and connected equipment.

The Ekip Dip LSI electronic trip unit combines long-time overload, short-time and instantaneous short-circuit protection in a robust protection platform. Together with the withdrawable Emax 2 construction, the 1SDA104640R1 provides a practical solution for large switchboards requiring high current capacity, substantial fault interruption capability and serviceable breaker construction.

Typical Applications

• High-current low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Large manufacturing and process plants.
• Power generation and infrastructure installations.
• Data centres and critical electrical infrastructure.
• Commercial and industrial distribution centres.
• Large switchgear and power-control assemblies.
