Resistive heater ClimaSys PTC 20W 110/250V NSYCR20WU2

Highly durable enclosure.

Resistive heater for control cabinets and ClimaSys enclosures PTC 20W

This compact resistive heater from Schneider Electric's ClimaSys series is a reliable solution for maintaining optimal temperature inside control cabinets, enclosures and other closed spaces. It provides effective heating, protecting sensitive components from the negative effects of low temperatures and moisture condensation.

The heater operates over a wide voltage range (110-250V AC), making it versatile in application. Its design based on a PTC element (Positive Temperature Coefficient) guarantees stable operation and self-regulation of heating power, preventing overheating. Made of durable aluminum, it is resistant to corrosion and mechanical damage. Mounting is done with practical clips, making installation and servicing easier.

Application and benefits:

• Protection against condensation: Maintains the temperature above the dew point, eliminating the risk of moisture condensing on electrical and electronic components.

• Stable temperature: Provides optimal operating conditions for devices, extending their life and improving reliability.

• Universal voltage: Possibility of powering from 110V and 250V AC networks – ideal solution for different markets and installations.

• Simple installation: Quick and easy mounting with clips in the vertical position – saving time and installation costs.

• Safety: Compliance with UL and VDE standards confirms a high level of safety. IP20 protection provides basic protection against touching.

• Efficiency: 20W power is sufficient to heat small spaces while ensuring low energy consumption.

Design and installation:

The heater has a solid construction made of extruded aluminum, which ensures durability and efficient heat distribution. A 300 mm (2 x 0.75 mm²) cable is used for electrical connection. Remember that the heater should always be installed with a temperature regulator for precise control of the temperature inside the enclosure and with appropriate electrical protection on the power supply side. The enclosure should be sealed to prevent circulation of outside air, which could disrupt the operation of the heating system.
