1SDA058911R1 ABB E4H/E/f/MS 3200 3200A 4-Pole Fixed 1000V DC Switch-Disconnector

Why Choose the ABB E4H/E/f/MS 3200 4-Pole 1000 V DC Fixed Switch-Disconnector?

The ABB E4H/E/f/MS 3200 is a heavy-duty 3200 A four-pole DC switch-disconnector engineered for dependable high-current switching and isolation at up to 1000 V DC. Part of the ABB SACE Emax E4 platform, this specialist configuration is designed for demanding direct-current distribution systems where high voltage, substantial current capacity and robust isolation performance are required.

Unlike an Emax automatic circuit breaker equipped with an electronic overcurrent release, the E4H/E/f/MS is a switch-disconnector without integrated overcurrent protection. Its specialised 1000 V DC configuration provides a rated short-time withstand current of 65 kA for 1 s, enabling the device to withstand substantial prospective fault currents while appropriately coordinated protective equipment clears the fault.

The 1SDA058911R1 is a four-pole fixed switch-disconnector with full-size neutral and horizontal rear terminals. Rated at 3200 A, it combines permanent switchboard installation with rear bolted power connections and a high-voltage DC design, making it particularly suitable for large DC distribution assemblies and other high-power installations requiring reliable circuit isolation.

High-Current 1000 V DC Switching and Isolation

The ABB E4H/E/f/MS 3200 is specifically configured for demanding 1000 V DC applications where conventional AC switching equipment is unsuitable. Its four-pole architecture and high-current Emax platform provide dependable switching and isolation for substantial DC power systems, while the 65 kA one-second short-time withstand rating supports coordination in installations with high prospective fault currents.

The fixed construction and horizontal rear power terminals make the 1SDA058911R1 particularly suitable for permanent installation within high-capacity distribution switchboards. With a 3200 A continuous current rating, full-size-neutral configuration and proven SACE Emax mechanical architecture, it provides a robust solution for specialised high-voltage DC distribution applications.
