Schneider Electric NSYCCOTHO ClimaSys thermostat simple °C (NA fan) content_copy

The ClimaSys CC from Schneider Electric is a simple thermostat for temperature control in enclosures and industrial systems. It serves as a temperature switch to control fans or other ventilation units, maintaining the internal temperature of the enclosure within a specified range. The device features a bimetal sensor that detects ambient temperature and activates a NO contact (make contact) when the set threshold is reached. The temperature can be adjusted in the range of 0 to 60 °C, with the display showing the current temperature in degrees Celsius. The hysteresis is 7 K ± 0.4 K, meaning the switch only resets when the temperature drops by 7 Kelvin below the set point, preventing unwanted switching cycles.

Applications
This thermostat is designed for use in industrial enclosures and control systems where simple, reliable temperature control without electronic control is sufficient. It is particularly suitable for applications where the enclosure temperature is monitored and a ventilation unit is activated if a threshold is exceeded. The operating ambient temperature of the device ranges from -20 to 80 °C, enabling use in a wide range of industrial environments.

Functions and Equipment in Detail
The device features one output for ventilation function, implemented via a NO contact. The maximum switching capacity is 2 A at 120–250 V AC inductive (pf: 0.6), 10 A at 250 V AC resistive, 15 A at 120 V AC resistive, and 30 W at DC. Electrical connections are made via four terminals with a capacity of 2.5 mm², enabling secure and stable connections to standard cables. The contact life is 100,000 switching cycles, indicating high mechanical durability.

Technology Explained Simply
The bimetal sensor responds to temperature changes through mechanical deformation, closing or opening the contact. This mechanism is robust, maintenance-free, and requires no external power supply for the sensor technology. The protection rating IP20 means the device is protected against contact with fingers and against solid objects larger than 12.5 mm, but not against water or dust. Therefore, it is suitable for use in enclosed, dry enclosures, but not outdoors or in damp environments.

Compatibility and Accessories
The thermostat is part of the ClimaSys product series and can be combined with various components from this series to create a complete climate control system for enclosures. Compatible products include, for example, the ClimaSys PTC heating element (NSYCR100WU2), the ClimaSys Smart Ventilation grille (NSYCAG125DG), the SmartFan (NSYCVF85M230DG), and the Thermal Hub (NSYCCOFSEM8U2). These components enable extended control and monitoring of enclosure climate control.

Mounting and Installation
Mounting is done via a clamped connection on a 35 mm DIN rail, but installation on cross braces, mounting plates, or special profiles is also possible. The device must be mounted vertically to ensure correct operation of the bimetal sensor. The device is made of PC (polycarbonate), is light grey, and meets the flame retardancy class UL94 V0, indicating self-extinguishing properties in case of fire. Dimensions are 68 mm (height) × 33 mm (width) × 44 mm (depth), and the product weight is 40 g.

Operational Advantages
The thermostat is characterized by simple installation, long service life, and reliable mechanical operation. It requires no external power supply for the sensor technology and is thus independent of electronic controls. The UL certification confirms the safety and reliability of the device for use in industrial systems. The compatibility with other ClimaSys components allows flexible expansion of the climate control system according to requirements.

Product Certifications
The device is certified with UL, confirming compliance with safety standards for electrical equipment in the USA and other markets. The protection rating IP20 and flame retardancy UL94 V0 contribute to safety and meet requirements in industrial environments.

Material and Color
The housing is made of PC (polycarbonate), a robust and durable plastic suitable for industrial applications. The color is light grey, providing good visibility in enclosures. The self-extinguishing property according to UL94 V0 reduces fire risk in case of short circuit or overheating.

Operating Environment
The device can operate at ambient temperatures from -20 to 80 °C, enabling use in a wide range of industrial environments. The input voltage is 240 V, making it suitable for use with standard mains voltages.

Connection and Wiring
Electrical connections are made via four terminals with a capacity of 2.5 mm², enabling secure connections to standard cables. The terminals are designed for easy and quick installation.

Warranty
The device comes with an 18-month warranty, underscoring the quality and reliability of the manufacturer.
