Key Features:

• Automatic Reset: Resets automatically once the temperature returns to the defined reset level.
• Temperature Range: Nominal switching temperature from 60°C to 250°C with specific tolerances.
• Compact Design: Diameter of 8.6mm and thickness of 4.5mm, fitting in tight spaces.
• High Voltage & Current Ratings: Operates up to 500V AC / 14V DC with current ratings of 1.6A to 7.5A.
• Durability: Vibration resistance of 100 m/s² and contact resistance ≤ 50 mΩ.

Construction:

• Main Parts:

  1. Ceramic cover plate
  2. Stationary silver contact
  3. Spring disc
  4. Movable contact
  5. Conductive housing
  6. Bimetal disc

• Mechanism:

  • Normal operation maintains the movable contact in close contact with the stationary silver contact.
  • At the rated temperature, the bimetal disc deforms, opening the contact to interrupt the circuit.
  • As the temperature falls, the protector resets automatically, closing the contacts and restoring the circuit.

Specifications:

• Nominal Switching Temperature: 60°C - 250°C
• Operating Voltage Range: Up to 500V AC / 14V DC
• Rated Current (AC): 1.6A to 7.5A
• Insulation Voltage: Housing is not insulated
• Approvals: UL/TUV/CQC/CB
• Total Bounce Time: < 1 ms
