Products & Services
Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits.
Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions.
Ground fault relays protect electrical equipment from ground faults. A ground fault is an unintentional current path between a current-carrying conductor and a grounded surface.
Ground fault circuit interrupters (GFCI) disconnect a circuit when the current between the neutral conductor and the live conductor becomes unbalanced. GFCIs are also known as residual current devices.
Fuse holders are devices for containing, protecting and mounting fuses. Blown fuses can be changed quickly and easily when used in conjunction with a fuse holder.
