Cabinet Heaters for Electrical Enclosures

Wattage range 10W, 20W, 50W, 100W, 150W

Use cabinet size and minimum ambient temperature before choosing the heater output.

Voltage options 120-240V AC, 230V AC, AC110V/220V/380V or DC220V/380V

Match the cabinet supply and control method before sample order.

Mounting styles screw fixing, clip fixing, clip fixing or screw fixing

Check DIN rail, clip or screw fixing against available cabinet space.

Fan heater options SG.CS018.150W, SG.CS018.250W, SG.CS018.400W

Use airflow models when faster heat distribution is needed.

Anti-condensation

Start with cabinet dimensions, humidity risk, indoor/outdoor condition and whether a hygrostat is required.

Low-temperature startup

Share the lowest ambient temperature, target internal temperature, supply voltage and startup timing.
