Multicomp Pro MP-33-200 Thermal Switch, NC, 200°C

The Multicomp Pro MP-33-200 Thermal Switch is a precision snap-action thermostat engineered for reliable temperature control. Operating as a normally closed (NC) switch, it senses temperature changes and automatically activates or deactivates connected heating or cooling systems at a set point of 200°C, with a reset at 160°C. This automatic reset functionality ensures continuous, hands-free regulation within a system, making it an indispensable component for maintaining consistent environmental conditions.

Constructed for durability and consistent electrical performance, the switch features AgNi/Cu (T2) stationary and movable contacts, a brass stationary arm, and a robust housing made from PF case and top cover with an aluminium cap. The internal bimetal disc mechanism, paired with an alloy copper movable arm and copper rivets, provides a reliable and swift snap-action response to temperature fluctuations. Its brass terminals, finished with nickel plating, offer excellent conductivity and corrosion resistance.

Designed for secure integration, the switch features a flange mount for stable attachment to surfaces and quick-connect sensor terminals for straightforward wiring. It is rated for robust electrical loads, handling up to 250V AC at 10A (16A max), with high dielectric strength and insulation resistance to ensure safety and longevity in demanding applications.

This component meets rigorous international safety and performance standards, including GB14536.1-2008, GB14536.10-2008, GB/T22687-2008, EN60730-1, and EN60730-2-9. Its compact dimensions allow for versatile installation in space-constrained environments.
