One-shot bimetallic sensitive temperature limiter - Thermorex TK32OS

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 operating with one-shot action and has no reset option.

This temperature limiter is available only with contacts that open as the temperature increases.

With variety of standard and custom configurations it provides reliable one-shot over-temperature protection and meets the specific technical needs of our customers, assuring maximum design flexibility. It is used in broad range of domestic, industrial and commercial applications.
