Serial Control Switch Relay Features Series 24 Serial Communications
Electroswitch announced its Series 24 serial control switch relay (SCSR) that facilitates remote control and monitoring of circuit breakers while retaining local control through a manual trip/close handle. An addressable network device with certified DNP 3.0, the SCSR combines the functions of various other devices and provides remote trip-coil monitoring (single or dual), sequence-of-events reporting, system battery monitoring and self-diagnostic reporting. The SCSR’s color LEDs indicate breaker position (also indicated with a built-in mechanical target flag), breaker-trip-coil integrity, serial-bus transmission/reception and local/remote mode. Rotor contacts are double-wiping and made of silver inlay phosphor-bronze. Stationary contacts are silver-plated with integral screw-type terminals. Each contact handles full rated current (30A/600V continuous).
