Rittal 3105380 PTC Enclosure Heater with Fan, 230V

Rittal 3105380 PTC Enclosure Heater with Fan, 230V

The Rittal 3105380 PTC enclosure heater with integrated fan regulates relative humidity and keeps enclosure interior temperatures above the dew point, preventing condensation-related corrosion and electrical short circuits. This fan-assisted version delivers a continuous thermal output of 235-800 W (250 W-265 W at 10 °C) and operates on a 230 V, 1~, 50 Hz/60 Hz supply. Built from durable plastic with an IP 20 protection rating and Protection Class II total insulation, it is engineered for reliable, code-compliant installation inside industrial enclosures and control panels where moisture control is critical.

Key Features

• Continuous Thermal Output: 235-800 W, with a rated output of 250 W-265 W at 10 °C, for effective enclosure heating.
• Integrated Fan: Fan-assisted version promotes even heat distribution throughout the enclosure interior.
• Durable Construction: Plastic housing for reliable, long-term performance in enclosure environments.
• Rated Operating Voltage: 230 V, 1~, 50 Hz/60 Hz for standard single-phase supply compatibility.
• Protection Rating: IP 20 to IEC 60 529 and EN 60 529, with Protection Class II (total insulation).
• Operating Temperature Range: -33 C-65 C for wide-range application suitability.
