The ABB YC-1SDA038302R1 is a shunt closing release coil accessory designed for use with ABB Emax low-voltage air circuit breakers. It provides the capability for remote electrical closing (i.e., remote closing actuation) of the circuit breaker when an external control voltage is applied. This accessory is typically used in automated electrical control panels and power distribution systems where remote or automated breaker control is required. It enhances operational flexibility by enabling the breaker to be closed electrically from a control system, PLC, or operator panel.
