Multicomp Pro MP-11-30/20 Thermal Switch, Normally Closed, 30°C

The Multicomp Pro MP-11-30/20 Thermal Switch is a reliable snap-action thermostat engineered to provide precise temperature control. It acts as a safety and regulation component, automatically sensing when the ambient temperature reaches its set point of 30°C and breaking the circuit (being Normally Closed) to deactivate a heating system or activate cooling. This automatic reset function ensures the system resumes operation once the temperature drops to the reset point of 20°C, making it ideal for maintaining consistent thermal conditions.

Constructed for durability and consistent performance, its key components include silver-nickel/copper (AgNi/Cu) contacts for reliable switching, a brass stationary arm, and a bimetal disc actuator housed within a robust PF (phenolic) case with an aluminium cap. The design incorporates a ceramic actuator pin and a SUS430 stainless steel flange for secure mounting. This switch is rated for 16A at both 125V and 250V, suitable for a wide range of electrical loads in control circuits.

Adherence to major international safety and performance standards, including UL60730, EN60730, and relevant GB standards, underscores its reliability for commercial use. With high insulation resistance (above 100MΩ) and low contact resistance, it ensures electrical integrity and efficient operation. Its compact, flange-mount design facilitates easy and secure installation onto heatsinks or equipment surfaces, providing a direct thermal link for accurate sensing.

An essential component for automated temperature management, this thermal switch is a fundamental building block in creating safe, efficient, and self-regulating systems across numerous industries and applications.
