HG140 DIN-Rail PTC Cabinet Heater – 15 W to 150 W, 120-240 VAC/DC, Self-Limiting

Description

DIN-rail PTC semiconductor heater for control cabinets, RTU and PLC enclosures and instrument boxes that must stay dry and above freezing through winter. The PTC element limits its own surface temperature, so heat output drops as the enclosure warms up.

• Keeping batteries, displays and 4-20 mA electronics inside their temperature range in winter
• Generator, ATS and pump control cabinets

Control

The heater has no on/off thermostat of its own. Wire it through a cabinet thermostat with an NC contact, such as our KTO011 DIN-rail cabinet thermostat, so it runs only when the enclosure is cold.

Note: this heater is not a hazardous-location certified device. Install it in general-purpose areas or inside an enclosure suitable for the location.
