Multicomp Pro MP-11 Thermal Switch NC Manual Reset 120°C

Multicomp Pro MP-11 Thermal Switch is a normally closed, manual reset thermal switch with a 120°C set point and a 10A at 250V AC electrical rating, suited to temperature control applications.

Overview

The switch uses a snap-action design that opens the circuit when the surrounding temperature reaches 120°C, which can halt a connected heating system or activate cooling to maintain the desired thermal environment. Manual reset requires user intervention to restart the system after a temperature trip event, adding a layer of protection against overheating. The bimetal disc mechanism is designed to provide consistent switching performance, and the switch is secured with a flange mounting for attachment to various surfaces.
