One-shot bimetallic sensitive temperature limiter - Thermorex TK32OS

Temperature limiter TK32OS (one shot) (DIN EN 60730-1) 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.

APPLICATIONS: This temperature limiter prevents overheating in a broad range of consumer, industrial and commercial products.

Note: With variety of standard and custom made configurations the limiter provides reliable one-shot over-temperature protection and meets the specific technical needs of our customers, assuring maximum design flexibility.
