Multicomp Pro Thermal Switch NC, 90°C

The Multicomp Pro Thermal Switch is a normally closed (NC) thermostat switch engineered for reliable thermal protection and control across a broad spectrum of applications. Operating at a fixed switching temperature of 90°C (±5%), its core mechanism utilises a thermo-bimetallic snap-disc to ensure precise and responsive action. Upon reaching its set temperature, this double-contact system reliably opens or closes the application's circuit, providing essential safety and automation functions.

Heat transfer to the switch occurs via convection or direct conduction from all sides of its robust housing, making its installation versatile. Its design, wide performance range, and diverse executions allow it to function as a protective switch, sensor, or controller, particularly where low-voltage, signal-current operations necessitate its gold-plated contacts.

Applications

This component is universally applicable in areas requiring dependable thermal monitoring. Key uses include safeguarding motors from overheating, protecting transformers and coils, integrating into electronic control systems, serving as a sensor in process automation, and monitoring temperature in various industrial and domestic equipment.
