RITTAL SK3105.330 enclosure heater without a fan

The Rittal SK 3105.330 is an enclosure heater without a fan, designed to regulate humidity and prevent condensation inside electrical enclosures. This helps to protect sensitive electronic components from damage due to corrosion or short circuits.

Here's a detailed description of its features and specifications:

Key Purpose:

• Condensation Prevention: Its primary function is to maintain an internal enclosure temperature above the dew point, thereby preventing condensation from forming. This is crucial for the longevity and reliability of electrical and electronic components.

• Humidity Regulation: By heating the enclosure, it helps to regulate relative humidity levels, creating a more stable and controlled environment.

Design and Construction:

• Compact Size: It has a compact design, making it suitable for various enclosure sizes.

• Material: Constructed from anodized aluminum, ensuring durability and efficient heat transfer.

• No Fan: This version operates without a fan, meaning it relies on natural convection for heat distribution. For larger enclosures or more even heat distribution, it's recommended to install multiple lower-output heaters or consider models with fans.

• PTC Heater: Utilizes PTC (Positive Temperature Coefficient) heating technology, which typically means it has a self-regulating heating element that prevents overheating.

Electrical Specifications:

• Rated Operating Voltage: 110-240 V AC (single-phase), 50/60 Hz. It can also operate on 110 V DC.

• Continuous Heating Output: 23-30 Watts (at 10 °C). Note that the continuous thermal output range for this series can be 10 – 150 W, but for this specific model, it's 23-30W.

• Pre-fuse: Requires a miniature circuit-breaker/fuse of 4 A.

• Protection Class: II (all-insulated).

Dimensions (W x H x D):

• 64 mm x 155 mm x 56 mm

Operating Conditions:

• Operating Temperature Range: -33 °C to 65 °C

• IP Protection Category (to IEC 60529): IP 20

Installation and Accessories:

• Supply Includes: PTC heater, quick-connection terminal, and assembly parts.

• Recommendations:

• A thermostat is recommended for precise temperature control.

• A hygrostat is recommended to regulate heating and prevent condensation on assemblies.

Approvals:

• CSA

• UR + C-UR (recognized)

Product Lifecycle:

• Currently an "Active" product in Rittal's sales documentation.

In summary, the Rittal SK 3105.330 is a reliable, compact, and fan-less enclosure heater designed to protect sensitive equipment within industrial enclosures from the damaging effects of humidity and condensation.
