ProMelt ContactorPro™ 50 amp panels for 120/208/240/277 VAC

ProMelt Contactor Pro panels provide industry leading automatic snow melting and deicing control. This turn-key solution is all you need for activating larger systems of ProMelt Mats and Cables. Connect your choice of a PM-224, PM-824, or PM-HSC5 snow sensor control. The CP panels are offered in three sizes: 50 Amps, 100 Amps, and 200 Amps. 120, 208, 240, or 277 VAC is supplied to this panel and an included 24V Class 2 transformer allows easy connection to the snow sensor.

Every Contactor Pro panel comes complete with 'system on' indicator light, manual override via 4-hr dial timer, and simple 24V wire terminal connections to the snow sensor. A new feature allows any CP series panel to be connected to any other CP series panel as an expansion panel. i.e. you can connect 2 panels together for added capacity using 1 snow sensor.

The CP-50 has one 50-amp contactor, the CP-100 has two 50-amp contactors, and the CP-200 has four 50-amp contactors. Systems should be designed to connect one or more ProMelt Cables or Mats in combinations not to exceed the capacity of individual 50-amp contactors

We recommend adding the optional PM-DP remote ProMelt Display Panel for the easiest monitoring and control of your sensor. The PM-DP wired remote is a great upgrade and is sold separately.
