Rittal 3105 Series PTC Enclosure Heater with Integrated Fan, IP 20

Rittal 3105 Series PTC Enclosure Heater with Integrated Fan, IP 20

The Rittal 3105 Series PTC Enclosure Heater with Integrated Fan is engineered to regulate relative humidity, prevent internal enclosure temperatures from dropping below the dew point, and stop condensation from forming inside electrical enclosures. This fan-assisted heater delivers a continuous thermal output of 235 - 800 W (235 W/250 W at 10 °C) and is available in 115V or 230V, 1~, 50 Hz/60 Hz configurations to match your facility's supply. Built with a plastic housing and Protection Class II (total insulation) design rated IP 20, it helps guard against the corrosion and electrical short circuits that condensation can cause inside panels and cabinets.
