Thermorex TK32

Bimetallic sensitive temperature limiter with manual reset control.

THERMOREX TK32

This is a temperature sensitive device, which is intended to keep a temperature below one particular value during normal operating conditions, automatically switching off the electrical circuit. This device is not self-resetting and operates with manual reset option. It prevents overheating in variety of consumer, industrial and commercial products. This temperature limiter is available only with contacts that open as the temperature increases. The contacts may be reset by manually pushing on the reset button after the device has cooled below the open temperature calibration. Besides its variety of standard configurations this limiter can also be customized to the specific technical needs of the customer, assuring maximum design flexibility and usage in broad range of temperature control applications.
