1SDA073465R1 ABB E6.2H/MS 5000 4p FHR Switch Disconnector

Why Choose the ABB E6.2H/MS 5000 4p FHR Switch Disconnector?

The ABB E6.2H/MS 5000 4p FHR, order code 1SDA073465R1, is a high-current SACE Emax 2 switch disconnector designed for dependable switching and isolation in demanding low-voltage power distribution systems. Built on ABB's E6.2 platform, this fixed four-pole device provides a 5000 A rated uninterrupted current and is intended for major industrial, infrastructure and critical-power switchboards.

The E6.2H/MS configuration is a circuit-breaker-derived switch disconnector intended for switching and isolation rather than integral electronic overcurrent protection. Its H performance level provides a rated short-time withstand current of 100 kA, enabling the device to carry substantial fault current for the specified short-time duration while separate protective equipment provides overload and short-circuit protection.

The 1SDA073465R1 is supplied in a fixed four-pole configuration with horizontal rear terminals. It is rated for operation at up to 690 V AC, with a 1000 V AC insulation voltage and 12 kV impulse withstand voltage, making it a robust isolation solution for high-capacity switchboards and busbar systems.

Key Advantages

• Very high 5000 A rated uninterrupted current for major low-voltage distribution systems.
• Four-pole configuration for switching and isolation in suitable three-phase four-wire networks.
• 100 kA rated short-time withstand current for high fault-level installations.

High-Current Four-Pole Switching and Isolation

Switch disconnectors provide a dependable means of making, carrying and isolating electrical circuits while dedicated protective equipment elsewhere in the installation provides overload and short-circuit protection. In high-capacity distribution systems, strong short-time withstand performance allows the switching device to remain suitable for installations where substantial prospective fault currents may occur.

The ABB E6.2H/MS 5000 combines a 5000 A continuous-current rating with a 100 kA short-time withstand capability for both 1 s and 3 s. Its fixed four-pole construction and horizontal rear terminals make it particularly suitable for high-capacity switchboards requiring dependable isolation, substantial current-carrying capability and efficient rear busbar integration.
