Multicomp Pro Thermal Switch NC 110°C 10A

The Multicomp Pro Thermal Switch NC (Normally Closed) is a precision thermostat switch engineered for reliable temperature control in a wide range of applications. Featuring a thermo-bimetallic snap-disc with a fixed switching temperature as the switching element, this switch responds accurately to external temperature changes, opening or closing the circuit as needed.

Designed for universal application, this thermal switch offers a wide performance range and diverse execution options, making it suitable as a protective switch, sensor, or controller. Its heat transfer is optimised via convection or direct heat conduction onto the housing, ensuring efficient operation. The switch is particularly well-suited for temperature sensing applications with low voltage and signal currents, thanks to its gold-plated contacts.

Key Features

• Normally Closed Contact: Ensures circuit continuity until the specified temperature is reached.
• High Switching Capacity: Rated at 10A or 6A at 250V, 50/60Hz (power factor 0.95 / 0.6).
• Fixed Switching Temperature: 110°C with a ±5°K tolerance, ensuring precise operation.
• Durable Construction: Withstands 10,000 switching cycles under rated current for long-lasting performance.
• Versatile Design: Available in manifold executions, including special low voltage variants.
• Approved Safety: VDE, UL, and cUL approved for peace of mind.

With a compact cylindrical housing and wire leads, this thermal switch is easy to integrate into various systems. It offers a low contact resistance of less than 50mohm (including 100mm wire), ensuring efficient current flow. The switch operates across a temperature range from 70°C to 190°C (in 5°C steps), providing flexibility for different thermal management needs.
