Multicomp Pro Thermal Switch NC 90°C

The Multicomp Pro Thermal Switch NC 90°C is a normally closed thermostat switch with a fixed switching temperature of 90°C (±5°K) for reliable temperature control.

This thermo-bimetallic snap-disc switch opens or closes its circuit in response to external temperature changes. Heat is transferred to the switch housing through convection or direct conduction, enabling a rapid response. The switch is current-insensitive, so it suits both power and signal applications, including low-voltage sensor circuits where gold-plated contacts support low-current performance.

Key Features

• Normally closed contact operation for fail-safe temperature monitoring
• Rated current 10 A / 6 A at 250 V, 50/60 Hz (power factor 0.95 / 0.6)
• Operational life of 10,000 switching cycles under rated current
• Available temperature range of 70°C to 190°C in 5°C steps, with this model fixed at 90°C
• Contact resistance of less than 50 mΩ (including 100 mm wire)
• VDE, UL, and cUL approved
• IP00 degree of protection to EN 60529
• U294 bead and L310 lead configurations
