OT630ES04K ABB 630 A 4-Pole Side Operated Switch Disconnector with Direct Handle

Why Choose the ABB OT630ES04K 630 A 4-Pole Switch Disconnector?

The ABB OT630ES04K, order code 1SCA022860R2590, is a robust 630 A 4-pole switch disconnector designed for reliable switching and isolation of low-voltage electrical circuits. As part of the proven ABB OT switch-disconnector range, this model combines high-current switching capability with a side-operated mechanism and a convenient direct-mounted operating handle.

Designed for industrial power distribution, switchboards and machinery, the OT630ES04K features base mounting and a black direct-mounted ON-OFF handle. Unlike the handle-free OT630ES04 variant, the OT630ES04K is supplied with its direct operating handle, providing a complete manual switching solution for installations where operation directly at the switch is required.

With a rated continuous current of 630 A, a maximum rated operational voltage of 1000 V AC and an AC-23 operational power rating of 355 kW at 400 V, the OT630ES04K is engineered for demanding industrial loads. Its four-pole configuration enables simultaneous isolation of four conductors, while the included terminal bolt kit simplifies integration into electrical assemblies.
