About the Marley CDFDS
The CDFDS is the optional power disconnect switch accessory for Marley and Qmark commercial downflow ceiling heaters. It is a 3-pole switch rated 30 amps at up to 600 volts, three-phase, 60 Hz.
Marley lists it as a field-installed accessory, and the heater specification calls for the disconnect switch to sit inside the heater enclosure. It gives a way to cut power to the heater at the unit itself.
Check your heater against the compatible-models list on this page before ordering.
Installation Tips
Turn off power to the heater at the breaker or main disconnect before opening the enclosure. Installation should be done by a qualified electrician following the heater's wiring instructions.
