Disconnect Switches
Disconnect Switches
Disconnect switches, also called safety switches or simply disconnects, are used to ensure an electrical circuit is completely cut off from its power source for service or maintenance.

They are not usually intended for normal control of the circuit, and thus typically open or close only after current has been interrupted by another device. Some applications use disconnects as fault protection for heavy machinery. Disconnect switches also often have lockout-tagout provisions, to prevent inadvertent or unauthorized operation.

As a primary safety disconnect device, disconnect switches are an NEC requirement in industrial and manufacturing facilities established by the National Fire Protection Association (NFPA).

Socomec FUSERBLOC series are fusible disconnect switches are heavy duty switches that break and make power circuits on and off load. The switches employ double break contacts per pole that ensure complete isolation of the fuse when the switch is in the off position. These switches are extremely durable and are tested and approved for use in the most demanding applications. The test position function is enabled with handles with the test position. This function tests the control circuit auxiliaries without switching the main contacts. It is a simple alternative to a separately wired push button.
