Multicomp Pro MP-11 Thermal Switch, Normally Closed, 15°C

The Multicomp Pro MP-11 Thermal Switch is a precision snap-action thermostat designed to automatically regulate temperature by activating or deactivating connected systems. This normally closed (NC) device senses a temperature change at its set point of 15°C, opening the circuit to control heating or cooling equipment accordingly. It ensures reliable operation in a wide voltage range from 125V to 250V at 16A, making it a versatile component for various thermal management tasks.

Constructed for durability and consistent performance, the switch features a bimetal disc mechanism housed within a robust PF (phenolic) case and top cover. Key internal components include stationary and movable contacts made from AgNi/Cu (T2) alloy, a brass stationary arm, and an alloy copper movable arm. The actuator assembly consists of an aluminium cap and a ceramic pin, mounted on a sturdy SUS430 stainless steel flange for secure installation.

Key Features & Specifications

• Reliable Switching: Offers a set temperature of 15°C with a tolerance of ±3°C and resets at 5°C ±3°C.
• Robust Electrical Performance: Terminal resistance is below 50 MΩ at 5V DC/0.25A, with an insulated resistance above 100 MΩ when 500V DC is applied between terminals and the cap.
• Secure Flange Mounting: Designed for stable and secure mounting to surfaces, ensuring accurate thermal sensing.
• Comprehensive Compliance: Meets major international safety and performance standards including GB14536.1-2008, UL60730, and EN60730-1.

This auto-reset thermostat is an essential component for maintaining precise temperature control, offering a self-resetting function that eliminates the need for manual intervention after a temperature event.
