BACKGROUND

Circuit Breakers are re-usable over-current protective devices that open a circuit automatically at a predetermined over-current state.

Fuses are over-current protective devices with a fusible link that melts and opens a circuit on an over-current condition.

Disconnect switches are used to periodically remove electrical circuits from their supply source; we stock both fused and non-fused disconnect switches.
