Multicomp Pro Thermal Switch, Normally Closed, 100°C, 6A 250V, Wire Leads

The Multicomp Pro Thermal Switch is a normally closed thermal switch with a fixed switching temperature of 100°C (±5%) and a contact rating of 6A at 250V.

Overview

The switch uses a thermo-bimetallic snap-disc that opens or closes the circuit when the ambient temperature reaches the switching point. It is designed for temperature control and protection in electrical equipment. A double contact system supports efficient heat transfer via convection or direct conduction, and the normally closed contact makes the switch suitable for temperature sensing and control.

Key Features

• Thermo-bimetallic snap-disc with a fixed switching temperature
• Double contact system
• Normally closed (NC) contact operation
• Wire lead terminals for straightforward integration into circuits
• Cylindrical sensor housing with a robust housing
• Non-sensitive to current fluctuations
• Available in manifold executions, including a special low-voltage version
• Gold-plated contacts available as an option for low-voltage and signal current applications

Electrical Ratings

The switch supports a rated current of 13A or 6A at 250V, 50/60Hz (with power factors of 0.95/0.6). Contact resistance is less than 50 mohm, including 100 mm of wire, and the switch can withstand 1000 switching cycles under rated current. The temperature rating range is 70°C to 160°C (TA), with switching temperature available in 5°C steps.
