Tronic Time Delay Auxiliary Contact, 10-180 Second On-Delay, 10A 660V

Our review

This Tronic auxiliary contact is a front-mounting on-delay timer for control panels, the kind of block that holds a contact open for a set interval after the coil is energised. It suits electricians and panel builders adding a delay to a contactor or relay circuit without fitting a separate timer relay. The plastic body measures 80mm high by 50mm wide, rated 10A at 660V AC with 690V insulation voltage to IEC 60947-5-1. Before buying, confirm the delay range you need and that front mounting suits your contactor. Compare against dedicated timer relays and other auxiliary blocks on delay range, current rating and mount type.
