About the Marley 480100001

This is terminal block 480100001, listed in parts breakdowns for Marley, Qmark and Berko electric unit heaters.

A terminal block is the wiring connection point inside the heater. Marley's unit heater instructions note that terminal blocks in the control box are where the power supply and heater controls are connected.

Compare your heater's model number with the compatible-models list on this page before ordering.

Installation Tips

Disconnect power at the breaker before opening the heater's control box. The wiring diagram is located on the inside of the control box cover, and supply wiring must be suitable for 75°C.
