ABSTRACT:
Fuse state indicators for use with disconnect devices having a fuse are provided. Fuse state indicators include a housing having circuitry, a detecting means for detecting an open circuit condition, conductors adapted for electrical connection to a disconnect device so as to complete a circuit connecting the detecting means with a fuse of the disconnect device, and a signal transmitting means. The detecting means is configured to transmit a signal to the signal transmitting means for determining an operational state of the fuse. The signal transmitting means, in turn, is configured to transmit a signal to a remote device the state of the fuse.
