Nelson Heat Trace offers two types of power distribution panels for use with industrial heating cable systems. Both are available in single- and three-phase models with a range of voltage options, a choice of main circuit breakers from 100 to 225 Amps, and a choice of standard 12, 30 and 42 pole versions. The AP Series is for systems that use a single control source, such as an ambient thermostat or a snow sensing controller. The DP Series is for systems that require a dedicated power source, and is normally used in conjunction with a control and monitoring system or a pipe sensing thermostat. We also offer all the connection kits and accessories you need to complete the job.
