What is a fused disconnect switch?
A fused disconnect switch is a combination of a switch to disconnect the circuit and a fuse to shut the circuit off in the event of a problem. When installing or maintaining equipment on the circuit, or the circuit itself, the switch provides a method to manually shut off the power.
Do I need a fused disconnect?
Fused (or “fusible disconnects”) switches are most typically used in systems that carry an exceptionally high load, such as what can be found in major industrial equipment. This is because fused disconnects naturally carry a higher “Amps Interrupting Capacity,” or AIC.
Why use a non fused disconnect?
Non-fusible switches do not have an integral fuse option and provide no circuit protection. Quite simply, does your need require fuse protection at the switch, or is there upstream protection to eliminate this need at the switch? MENNEKES offers both non-fusible UL508 or fusible UL98 disconnects.
What is a fused switch used for?
