MICROTHERM T11A Series Thermal Cut-Out Switch, NC, 110°C

The MICROTHERM T11A Series Thermal Cut-Out Switch is a reliable and compact temperature limiter designed to protect sensitive components from overheating. This normally closed (NC) device activates at a precise switching temperature of 110°C, automatically interrupting the circuit to prevent damage. Its primary function is as a thermal motor protector, safeguarding transformers, coils, electronics, and sensors from excessive temperatures.

Featuring a high power rating and small dimensions (just 33mm x 22mm x 2mm), it is an ideal solution for space-constrained applications. The switch operates with no vibration noise, ensuring it won't interfere with the performance of delicate instrumentation. It is available in both normally closed and normally open output versions to suit different control circuit designs.
