Furnas Electric Corporation 40JB32AC Contactor

The Furnas Electric Corporation 40JB32AC Contactor is a size-4 AC coil contactor designed to switch electrical loads in control circuits. It carries the part number 40JB32AC and is manufactured by Furnas Electric Corporation. The AC designation indicates an alternating-current coil, which energises to close its contacts and power the connected circuit. In control systems, a separate control circuit energizes the coil to remotely switch power to loads. When energized, the contact set completes the circuit, while de-energizing the coil opens the contacts and isolates the load. This model is suitable for integration into motor control and automation wiring where a reliable remote switch is required.
