About the Marley 5823-0004-003

This is a factory replacement power terminal block, part number 5823-0004-003, for Marley, Qmark and Berko electric unit heaters.

It is sold as the terminal block only; the heater is not included.

Power blocks differ between heater sizes, so confirm your unit's model number in the compatible-models list on this page before ordering.

Installation Tips

Turn off power to the heater at the breaker before removing any covers or handling wiring.
