ACV Electromagnetic Relay 3TG 1010-0AL2 54452082

The ACV Electromagnetic Relay 3TG 1010-0AL2 (SKU 54452082) is a connector category component designed for circuit switching in boiler systems. It controls fans, valves, and pumps in compatible ACV boiler circuits. This relay is OEM-certified and features high electrical durability and fast switching response. It is compatible with ACV Prestige 50 MK2, HeatMaster 60, Compact 24, CA 150, and Comfort Delta Pro 45 models.

Parts of this type are selected by matching the relay's electrical ratings (coil voltage, contact current) and physical dimensions to the boiler's control board and mounting socket. Before ordering, verify the relay's pin configuration and switching capacity against the original part's specifications. Installation typically involves disconnecting power, removing the old relay, and plugging in the new one, ensuring a secure fit.

When relays of this kind fail, symptoms may include intermittent or complete loss of function in connected components such as fans, valves, or pumps. The boiler may fail to start, overheat, or display error codes related to these components. Check for signs of burning, melting, or a stuck contact, and test the relay's coil and contacts with a multimeter.
