About the Marley 5018-0004-100
Part 5018-0004-100 is a genuine Marley Engineered Products three-pole relay, also called a contactor, used in Marley, Qmark and Berko electric unit heaters. It has a 24-volt coil.
The contacts are rated at 35 amps, and it is a unit-mounted AC relay. This is the service part number that takes the place of the earlier 5018-0004-000.
Marley also makes 35A contactors with 120V and 208/240V coils under nearby numbers, so confirm you need the 24V-coil version and check your heater against the compatible-models list on this page.
Installation Tips
Shut off power to the heater at the breaker or disconnect before servicing.
