THERMIK thermal protectors of Series 01 and 02 are utilized for overheating protection of all kinds of electrical equipment or devices. They are most suitable for electrical motors where automatic resetting is required after overheating and subsequent cooling of the motor. The Series 01 is Normally Closed (NC), while the Series 02 is Normally Open (NO).

Due to the high pressure stability of the housing, they can either be attached on or embedded within coil windings. 

Design: These switches are equipped with a high capacity contact mechanism, wherein the bimetallic disc can move freely, without the current flowing through it. An additional spring disc maintains constant contact pressure until reaching its switching temperature.
