Multicomp Pro Thermal Switch, NC, 70°C

The Multicomp Pro MP-11-70/55/E111B14H221 is a robust and reliable snap-action automatic reset thermostat, designed to regulate temperature within systems by opening or closing a circuit in response to heat. This normally closed (N/C) switch activates upon reaching its 70°C ±3°C set point, and automatically resets once the temperature drops to approximately 55°C ±5°C, making it ideal for maintaining consistent thermal conditions.

Constructed for durability, it features high-quality materials including an aluminium cap, a PF (phenol formaldehyde) case and top cover, and a brass stationary arm. The internal bimetal disc is the key sensing component, ensuring precise and responsive action. The switch is rated for 10A at 250V AC, making it suitable for a wide range of electrical loads, and it offers excellent electrical insulation and dielectric strength for safe operation.

This thermal switch is certified to key international safety and performance standards, including EN60730-1, EN60730-2-9, and relevant GB standards, providing assurance of its quality and reliability. Its compact, flange-mount design allows for secure and straightforward installation onto surfaces, ensuring good thermal contact for accurate sensing.
