Control cabinet heater
Features
- An efficient solution for heating switchboard cabinets
- Low temperature protection
- Prevention of condensate formation
Approvals
Control cabinet heater is used to anticondensation heating and maintaining a positive temperature inside the cabinet.
The heating element is protected by a metal shell on both sides. This provides mechanical protection against damage.
The power cable is of a silicon wire that is resistant to overheating.
Heater materials have high electrical strength and insulation resistance for high reliability.
All heaters are factory tested.
To control the temperature inside the cabinet, the heating system is recommended to be combined with the PT-300 temperature controller, thermostat or hygrostat.
- An efficient solution for heating switchboard cabinets
- Low temperature protection
- Prevention of condensate formation
- Longer service life of electrical equipment
- High reliability
- Heating power control based on inputs from ambient sensors
- Mounting on a DIN-rail
