Thermostat -10÷80°C, 1NC EF-TER-NC 001344000

EF-TER-NC thermostat is a reliable temperature control element, widely used in electrical enclosures and heating systems. Its main function is to maintain the optimal temperature inside the enclosure, which translates to the correct operation of the devices installed in it. It is ideal for use with heaters, providing stable operating conditions.

Functionality and application

This thermostat has one normally closed contact (1NC), which means that under normal conditions the circuit is closed and opens only when the set temperature is exceeded. This makes it perfect for heating systems where its job is to turn on the heater when the temperature drops below the set threshold. The wide temperature adjustment range from -10°C to 80°C allows it to be adapted to various applications.

Construction and mounting

The EF-TER-NC thermostat is characterized by its compact dimensions (29 mm width, 72 mm height and 46 mm depth) and a solid housing made of PA66 UL94 V-0 – a material resistant to mechanical damage and external factors. Mounting is done on a standard TH35/15/32 rail, which facilitates installation and integration with existing infrastructure. Screw terminals with a range of 0.75 - 2.5 mm² ensure a secure connection of wires.

Technical parameters and safety

The device operates at a rated voltage of 110-250V AC or 12-60V DC and withstands a continuous current of up to 10A, and the maximum momentary current is 15A. The accuracy is ±3K, and the hysteresis is ±7K – these parameters guarantee precise temperature control. The thermostat has a protection degree of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. It meets the requirements of the CE standard, confirming its safety and compliance with European standards. The RAL 7035 housing color provides an aesthetic appearance and good visibility in various lighting conditions.
