Tronic Overload Relay 4A to 6A

Our review

This Tronic overload relay is a circuit-protection component for equipment drawing between 4 and 6 amps. Its job is simple but important: it stays closed during normal operation and opens the circuit when an electrical, thermal, or power overload occurs, cutting power before damage spreads. It is typically paired with a contactor, together forming a motor starter, which makes it relevant to anyone setting up or repairing motor-driven machinery. Before buying, confirm your motor's full-load current falls inside the 4 to 6 amp range, check the relay's physical fit and terminal arrangement against your existing setup, and match it to your contactor. Compare alternatives by current range, reset type, and mounting style, since these determine whether a relay drops into your panel or needs adaptation. If your load sits near the top of the range, consider whether a wider or higher-rated unit gives more headroom.
