Single Phase AC Electric Motor Thermal Protection
Cycles life: 6,000 cycles is a typical value for many applications.
Open temperature: The range of 50°C to 150°C covers typical operating temperatures for motors and other devices.
Temperature Tolerance: ±5°C is a reasonable tolerance for applications.
Differential Temperature: This value is crucial and should be specified for each open temperature setting. It determines the temperature rise above the open temperature that triggers the protector.
Seal: Epoxy resin is a common and effective sealing material.
Contact resistance: ≤50 mΩ is a low resistance value, which is generally desirable for minimal power loss.
Insulation resistance: >100 MΩ is a high value, indicating good insulation quality.
Lead wire pull strength: 30 N is a reasonable value for applications.
