Fuji Electric SRCa3631-O Magnetic Contactor

Fuji Electric SRCa3631-O Magnetic Contactor is a 20A rated switch designed to control electrical loads in automation and control panels. With a coil rated for 100–110 V, this device is actuated by the control circuit to energize or de-energize the connected load without manual operation. A magnetic contactor uses an electromagnetic coil to move a contact set, enabling remote initiation of power to line loads. The SRCa3631-O model name identifies Fuji Electric's contactor family, and the 20A current rating indicates the maximum current the contacts are designed to carry in normal operation, making it suitable for switching motors, pumps, or conveyors in industrial equipment and control panels. The coil-voltage specification helps determine compatibility with standard control circuits and relays, ensuring reliable energization from the intended control voltage.
