The Waukesha® Positive Temperature Coefficient heater
(PTC2) can improve the reliability, efficiency and
operational life of electrical equipment by automatically
maintaining an enclosure temperature only slightly higher
than the outside ambient temperature without using a
thermostat or controls. Our PTC2 performs this function
with a high velocity fan, all while taking up less space and
having no need for any special mounting platforms.
E LI M I NATE S TH E R M OSTAT PR OB LE M S
Our PTC2 heaters use a variable resistance (current limiting)
material that automatically controls cabinet temperature and
eliminates the need for a thermostat, increasing heater reliability
and efficiency.

PR EVE NTS H EAT DAMAG E AN D CON D E N SATI ON
During cold weather when significant heat is required to reach the
thermostat setting, a traditional strip heater is likely to drive the
temperature of the area around the heater well above desirable
levels. This can result in uneven heat distribution in the control box.
Waukesha® PTC2 heaters feature an integral circulating fan that
moves warm air around the cabinet, maintaining even heat distribution
and providing uniform condensation protection. The PTC2 offers even
better air velocity than the previous PTC, allowing for even more air
movement throughout the cabinet.
PTC2 heaters are available in the following configurations:
•2
0, 30, 40 & 60 Watt — dual rated for 120V–240V
• 200 Watt, Fan Forced*
• 300 Watt, Fan Forced*
• 400 Watt, Fan Forced*
* Specify either 120V or 240V
I N STALLS QU I CK LY
The electrical connections from the fan to the heater are prewired, so the only connection necessary is to provide power to
the assembly; our forced air PTC2 heaters include a 12 foot long
wire harness with quick-connect end for easy installation. Integrated
DIN-rail mounting clip allows for quick orientation in cabinet for
proper air circulation.
Snap-together
connection between
harness and heater
further simplifies
installation.
