Bimetallic sensitive temperature limiter with manual reset control- Thermorex TK32

Temperature limiter TK32 (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 not self-resetting and operates with manual reset option. The reset is achieved by manually pushing on the reset button after the device has cooled below the open temperature value.

The choice of its operational position is free. TK32 has normally closed contacts.

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

Note: Besides its variety of standard configurations the limiter can also be customized to the specific technical needs of the customer.
