The new Series 24 Serial Control Switch Relay (SCSR) from Electroswitch 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 can also save money by freeing up RTUs (Remote Terminal Units), reducing point-to-point wiring, simplifying testing and commissioning, and minimizing training.  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.
Electroswitch will configure the SCSR with up to 6 decks, each containing 2 isolated contacts enclosed in molded phenolic insulators.  Rotor contacts are double-wiping and constructed of silver inlay phosphor-bronze.  Stationary contacts are silver-plated with integral screw-type terminals.  Each contact is designed to handle full rated current (30A/600V continuous).  Trip/close hold time can range from 1 to 3 seconds serially selectable.  Baud rate can range from 1200 to 19,200.  Transient protection meets the standards of IEEE C37.90.1 and IEC 61000-4-4.  Switching action is 45° spring return to normal.  Mounting can be panel or 3-hole.
