Tronic Thermal Overload Relay 60-80A for AC Contactor 40-65A

Our review

This Tronic thermal overload relay sits between your AC contactor and the motor it drives, tripping the circuit when current climbs into the 60 to 80 amp band. It is made for contactors rated 40 to 65 amps, so it suits panel builders, workshop electricians and maintenance teams running pumps, compressors or similar motor loads where a contactor alone gives no overload protection. Before buying, confirm your contactor's rated current falls inside that 40-65 amp window and that your motor's full-load current sits within the relay's 60-80 amp setting range. Compare it with other thermal relays by checking whether their adjustment band and contactor match line up with yours, since a mismatch means the relay either trips early or never trips at all. The relay is available on Sokonia.
