Rittal 31053 3105 Series Fanless PTC Enclosure Heater, Anodized Aluminum, IP20

Rittal 3105 Series Fanless PTC Enclosure Heater, Anodized Aluminum, IP20

The Rittal 3105 Series Fanless PTC Enclosure Heater regulates relative humidity inside electrical enclosures, keeping internal temperatures above the dew point to stop condensation before it forms. Built from anodized aluminum with an IP 20 protection rating (per IEC 60 529 and EN 60 529), this fanless design is available in continuous thermal outputs of 10 W, 20 W, 30 W, and 150 W to match enclosures of different sizes. Rated for 110 V - 240 V, 1~, 50 Hz/60 Hz operation, it helps prevent the corrosion and electrical short circuits that condensation inside an enclosure can cause.

Why Rittal?

Rittal enclosure heaters in the 3105 Series use anodized aluminum construction and an IP 20-rated, double-insulated Protection Class II design to deliver dependable, code-conscious climate control inside electrical enclosures across a 10 W to 150 W output range. Pairing a unit with a thermostat or hygrostat, as Rittal recommends, enables precise temperature and humidity regulation, and larger enclosures can use several low-output heaters for even heat distribution. Choose Rittal for enclosure heating engineered to protect sensitive electrical components from moisture-related damage.
