Tronic 12A to 18A Overload Relay

Our review

This Tronic overload relay is a protective component for motor circuits, designed to open the circuit when an electrical, thermal or power overload occurs. It is normally closed, so it only opens under overload conditions, and it works as a motor starter when paired with a contactor. It suits anyone assembling or maintaining a motor control setup who needs overload protection rather than just switching. Before buying, confirm the relay's current range matches your motor's full-load current and that it is compatible with your contactor. Compare alternatives by their current range, reset type and whether they suit your contactor series, since these determine fit more than brand alone.
