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

The Multicomp Pro MP-11 Thermal Switch is a high-precision, snap-action thermostat engineered for reliable temperature regulation. It is designed as a normally closed (NC) switch, automatically opening the circuit when the surrounding temperature reaches its set point of 120°C, effectively halting a connected heating system or activating cooling to maintain the desired thermal environment. This manual reset function ensures safe operation, requiring user intervention to restart the system after a temperature trip event, providing an added layer of safety against overheating.

Constructed with durability in mind, this thermal switch boasts a heat-resistant casing rated for 170°C and features a robust electrical specification of 10A at 250V. Its precise bimetal disc mechanism ensures accurate and repeatable switching performance. The switch is secured via a reliable flange mounting, making it simple to attach securely to various surfaces for consistent temperature sensing.
