ABSTRACT:
A circuit breaker includes a microcomputer-based trip unit, and a remote indicator unit and power supply. The trip unit includes an optically-coupled data output system and means for generating a pulse code containing cause-of-trip information and excess demand alarm information. The remote indicator unit includes an optically coupled input circuit and a plurality of light emitting diodes to indicate cause of trip and excess demand alarm information upon receipt of an appropriate pulse code pattern. The remote indicating unit also includes relays to provide control of external alarm circuitry upon receipt of cause of trip and demand alarm information. The remote indicator unit further includes a power supply for supplying operating power to the remote indicator unit and to the trip unit. The power supply is powered both from an external AC line connection and from internal rechargeable batteries.
