RS PRO Bi-Metallic Thermostat, Closes at 35 °C, +150 °C Max, Normally Open, Automatic Reset, 16 A, Fixed Mount 222-8249

RS PRO 222-8249 Bi-Metallic Thermostat is a precision temperature control switch designed for reliable operation in a wide range of electrical devices requiring temperature management. It operates by using a temperature-sensitive bimetallic disc that actuates isolated electrical contacts, closing at 35 °C and capable of withstanding maximum temperatures up to +150 °C.

This thermostat is ideal for applications such as coffee machines, smoke detectors, heating systems, water boilers, and other appliances where temperature regulation and overheating protection are critical. Its compact and robust design with a fixed mount and horizontal tab terminals facilitates easy installation and replacement.

The switching mechanism provides a normally open (NO) contact with an automatic reset feature, which returns the switch to its default position once the temperature falls below the closing point. The device is rated for a contact current of 16 A and supports up to 250V AC and DC voltages, making it versatile for various electrical circuits.

Its bimetallic snap disc offers rapid response times to temperature changes while maintaining high reliability and durability. The thermostat complies with industry standards including ENEC17, UL/cUL, and CQC, ensuring it meets rigorous safety and quality benchmarks.

Manufactured in China, the RS PRO 222-8249 ensures consistent performance and long service life. The compact profile (half inch, approx. 12.4 mm height) allows it to be integrated into diverse appliance designs requiring dependable temperature control switches.

Operates between 0 °C and +150 °C with a closing temperature at 35 °C. Bi-metallic type for efficient thermal switching. Contact ratings: 16 A current, 250 V AC/DC voltage. Fixed mount with horizontal tab terminals. Automatic reset for repeated cycling without manual reset.
