AERCO Relays & Contactors

AERCO Relays & Contactors are electrical switches that allow low-voltage signals from control modules to safely operate higher-current devices like blowers, pumps, and draft inducers. Relays handle smaller control tasks, while contactors are built for the heavier electrical loads found in large boilers and water heaters. Using authentic AERCO Relays & Contactors ensures accurate switching, improved safety, and reduced electrical wear in repeat cycling applications.
