RS PRO Bi-Metallic Thermostat, Closes at 160 °C, +250 °C Max NC, Automatic Reset, 16 A, Fixed Mount 222-8246

RS PRO 222-8246 Bi-Metallic Thermostat is an industrial-grade thermostatic switch designed for precise temperature control and protection in a wide range of electrical devices. This thermostat closes at 160 °C and can withstand a maximum operating temperature of +250 °C, supporting a contact current of 16 A. The automatic reset feature allows the thermostat to revert to its normal operating state once temperatures return to safe levels.

The core of the thermostat’s operation is a temperature-sensitive bimetallic disc that acts as the actuator for thermally and electrically isolated contacts. These contacts open or close when the ambient or surface temperature reaches the predetermined snap point of the disc, ensuring accurate and reliable temperature regulation.

This model features a normally closed (NC) switch function with tab terminals and a fixed mount design, making it suitable for replacement or integration into new electrical appliances. It supports AC and DC voltages up to 250 V, covering a broad spectrum of industrial and commercial applications.

The thermostat switch complies with stringent safety and quality certifications including CQC, UL/cUL, and ENEC17, ensuring dependable performance. Its compact size, approximately 12.4 mm (½ inch) in height, allows easy replacement in devices like coffee machines, heating systems, boilers, and smoke detectors.

Designed for rapid thermal response, the low mass and small size of the bimetallic disc contribute to swift switching actions when temperature fluctuations occur, preventing overheating and potential damage to equipment. This makes it a reliable component for HVAC, sensing instrumentation, automotive, and industrial equipment.
