Belimo Safety Temperature Limiter STB 1m 50-80 °C/122-176°F Manual Reset EXT-J-00734645

This Belimo safety temperature limiter is designed for precise readings, with a measuring range of 50 and 80 °C (122 and 176 °F). The safety temperature limiter features a capillary of 1 m in length, providing ample reach for different applications. This safety temperature limiter utilizes a changeover (SPDT) output signal for the temperature switch. The output signal is 230 V AC/DC. The safety temperature limiter ensures reliable switching with a minimum switching current of 100 mA at 24 V AC/DC. The safety temperature limiter has a protection rating of IP54. This safety temperature limiter is ideal for monitoring temperatures in heating water systems, warm water systems, and other applications in heating, ventilation, and air conditioning systems. When the set temperature is reached, the 1-pin changeover contact (SPDT) is switched. The safety temperature limiter function works as follows: if the sensor's temperature exceeds the designated setpoint value, the transmission mechanics trigger the switching, subsequently opening or closing the electrical circuit and mechanically locking the switching in place. The unlocking difference stands at approximately 10K. When the temperature drops below the chosen setpoint value, the switch can be manually unlocked once more.

Pros:

• A sintered moisture protection coating on sensors shields against condensation, mechanical stress, and vibrations
• For temperature monitoring in hot water systems, heating water, and additional uses within ventilation, heating, and air conditioning systems
