Compact and lightweight (64 × 155 × 56 mm, 400 g), it provides 49–50 W heating power to prevent condensation and maintain stable internal cabinet temperatures in electrical enclosures.

Advantages

The heater delivers low-power, reliable heating without a fan, reducing dust circulation and mechanical wear. Its wide input voltage range (110–240 V) and compatibility with 50/60 Hz mains make it suitable for varied installations. The small footprint and light weight allow installation in confined enclosure spaces and retrofitting existing cabinets.

How to use

Mount the heater inside the electrical enclosure following the manufacturer's mounting points and secure electrical connection to a single‑phase AC supply (110–240 V, 50/60 Hz). Position the unit to allow free heat distribution within the cabinet while avoiding direct contact with sensitive components. Ensure connections are made with power disconnected and in accordance with local electrical standards.

Recommendations

For reliable operation, use the heater only in enclosures with appropriate ingress protection and follow Rittal installation instructions. Where precise temperature control is required, combine with a thermostat or control device compatible with the heater's power and supply specifications.
