Product Information
Full details
The Rittal 3105.380 enclosure heater is an essential tool for facility managers and electrical engineers tasked with protecting sensitive rack-mounted equipment from moisture-related failures. By maintaining temperatures above the dew point and regulating internal relative humidity, it effectively prevents condensation, corrosion, and short circuits within your enclosure. While it provides robust climate control for compact spaces, it requires professional electrical installation and adequate clearance for airflow to operate safely and efficiently.

FAQs
What is the primary function of this heater?
The heater is designed to raise the internal temperature of an enclosure to prevent moisture condensation and electrical corrosion.
Can this be used outdoors?
No. The heater is rated IP20, meaning it is not protected against water ingress and should only be used inside a protective enclosure.
Does this unit require a separate thermostat?
While it can be wired for continuous operation, it is highly recommended to use it with an external thermostat or hygrostat for energy efficiency.
What is the input voltage for the 3105.380?
This model is designed for a 230V AC power supply.
Is the fan replaceable?
The fan is built-in; if it fails, the entire unit usually requires inspection or replacement by an authorized technician.
How much space does this heater require?
The unit measures 200mm x 103mm x 103mm. You should allow additional clearance around it to ensure the fan can move air effectively.
Troubleshooting
Heater does not output warmth
Check the power supply connection and ensure the circuit breaker is closed. If a thermostat is connected, verify that the setpoint is currently triggering the device.
Fan is making loud noise
Ensure there is no debris obstructing the fan blades and that the heater is mounted securely to the enclosure wall to prevent vibration.
Condensation still forming
Check that the enclosure is sufficiently sealed and that the thermostat/hygrostat settings are appropriate for your local climate conditions.
Pros and Cons
Pros
- Reduces the risk of corrosion and short circuits in humid environments
- Self-regulating PTC heating mechanism
- Compact form factor ideal for restricted enclosure spaces
- Integrated fan ensures consistent temperature distribution
- Durable, professional-grade construction
Cons
- Requires a 230V power supply
- Surface mounting demands specific placement for optimal airflow
- IP20 protection rating is not suitable for harsh, dust-heavy, or wet outdoor environments
Setup, Compatibility & Care
Installation should be performed by a qualified professional in accordance with local electrical codes. The device is designed for surface mounting; ensure that the mounting surface is thermally stable and that there is sufficient clearance around the heater for the fan to intake and exhaust air effectively. Avoid blocking the airflow path with cables or equipment. The 230V power connection should be routed through a proper terminal interface. For maintenance, periodically inspect the intake of the fan for dust buildup. Since the unit has an IP20 rating, ensure the enclosure itself provides the necessary protection against environmental contaminants (IP rating reflects protection against solid objects, not water).
