DESCRIPTION
The CM-GP/AXPC100-CM-GP is an electronic
temperature controller with 30-mA ground-fault protection.
It is ideal for all heat tracing applications requiring accurate
temperature monitoring. The controller can be
programmed to maintain temperatures up to 215°C
(419°F) at voltages from 100 to 277 V and can switch
current up to 30 Amperes for the CM-GP or 25 Amperes
for the AXPC100-CM-GP. The CM-GP/AXPC100-CM-GP
is complete with a temperature sensor and is housed in a
NEMA 4X rated enclosure. The controller features an
AC/DC dry alarm contact relay for monitoring critical
applications such as fire protection piping.
These instructions are to be used together with the
installation and maintenance instructions for any heating
cable or power connection kits utilized with this controller.
