28 amp Relay (replaces all relays, requires large transformer)

The Hide-A-Hose MD 28 amp Relay (replaces all relays, requires large transformer) is a heavy-duty replacement relay for central vacuum electrical systems. Built In Vacuum says it replaces the smaller #240 and #241 relays and works with 110 to 240 volt motors and all mini breakers. It is specifically intended for systems using a large 24-volt transformer, and the company is very explicit that this relay only works with large 24-volt transformers.
