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.
  • Pre-Fuse Requirement: Miniature circuit-breaker/fuse rated 4 A for circuit protection.
  • Recommended Controls: A thermostat is recommended for precise temperature control, and a hygrostat is recommended to regulate heating and help prevent condensation on assemblies.
  • Larger Enclosures: In larger enclosures, even heat distribution is best achieved by installing several low-output heaters.
  • Included Hardware: Supplied with fasteners for mounting the PTC heater with fan, packaged as 1 pc(s) weighing 1.22 kg.

Rittal 3105380 – Frequently Asked Questions

1) Will the Rittal 3105380 enclosure heater run on 120V North American power?
No. The 3105380 is a 230 V, single phase, 50/60 Hz unit. On a 120 V supply it will not reach its rated output, so you need either a 230 V single-phase circuit (common in industrial panels as a two-pole derived 208/240 V feed) or a 120 V Rittal PTC heater model instead.
2) What size breaker or fuse does the Rittal 3105380 panel heater need?
Protect it with a 4 A miniature circuit breaker or fuse ahead of the heater. That is the pre-fuse Rittal specifies for this unit, and it is the amperage figure on the spec sheet.
3) How much heat does the 3105380 PTC heater actually put out, and how do I know if it's enough for my cabinet?
Continuous thermal output runs 235 to 800 W, with a rated 250 to 265 W at 10 degrees C. The PTC element self-regulates, so output rises as the surroundings get colder and tapers as the interior warms. For a large cabinet Rittal's own guidance is to use several lower-output heaters rather than one big one, because that gives more even heat distribution than a single point source.
4) Do I need a thermostat or a hygrostat with a Rittal PTC enclosure heater, and are they included?
Neither control ships with the 3105380. Rittal recommends a thermostat where you are holding a minimum interior temperature, and a hygrostat where the real problem is condensation on assemblies, since the hygrostat switches the heater on by relative humidity instead of temperature. Many panel builders fit both. Order the control separately; what comes in the box is the heater with fan and its mounting fasteners.
5) Can I mount a Rittal 3105380 heater in an outdoor enclosure?
Not exposed. The heater itself is IP 20 to IEC 60 529 / EN 60 529, which is touch protection only with no water ingress protection, so it belongs inside a closed enclosure. The enclosure provides the environmental rating; the heater just needs to sit in a dry interior. Ambient operating range is -33 to 65 degrees C, so an outdoor-rated cabinet in a cold climate is a normal application as long as the unit is inside it.
6) Why pick the fan-assisted Rittal PTC heater over a convection-only enclosure heater?
The fan is what moves the heat around. A convection heater stratifies, warming the top of the cabinet while the lower components stay near dew point; the 3105380's integrated fan pushes air so the whole interior comes up more evenly. Pick the fan version for taller or densely packed panels and for condensation control where you care about the temperature at the components, not just the air at the top. The 3105380 is the With Fan configuration.
7) Does the Rittal 3105380 need a ground connection?
No protective earth conductor is required. It is built to Protection Class II with total insulation, which is why the housing is plastic. Wire line and neutral through your 4 A pre-fuse and, if used, the thermostat or hygrostat contact.
8) What is the Rittal part number for the 230V PTC enclosure heater with fan?
Rittal 3105380. That is the manufacturer part number for the 230 V single-phase PTC heater in the fan-assisted configuration.
