Tronic 2.5A to 4A Overload Relay

Our review

This Tronic overload relay is a protective component for electrical circuits, opening the circuit when an overload occurs. It is normally closed, so it only opens under fault conditions. It suits anyone building or maintaining a motor starter, where it is attached to a contactor to provide overload protection. 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 trip range, reset type and mounting style, since these determine whether the relay fits your panel and application.
