The BW-ECM Epoxy Resin Thermal Protector from the BW-E series is a durable and efficient solution for protecting electrical devices from overheating. With a 2A power class, this normally closed thermal protector features blue epoxy resin insulation for enhanced safety and robustness. It automatically resets after cooling down, making it ideal for continuous operation. Key features include:

  • Power Class: 2A
  • Type: Normally closed (NC)
  • Reset: Automatic reset
  • Insulation: Blue epoxy resin for durability
  • Connector Cables: Included for easy integration

Main Components:

  1. Shell
  2. Base
  3. Bimetal Disc
  4. Movable Contact
  5. Temperature Calibration Plate
  6. Static Contacts

Construction: The movable contact is welded to the bimetal disc and attached to an iron bracket. The stationary silver contact and base are molded together as a single unit. Current flows through the bimetal disc and temperature calibration plate, connecting the movable and static contacts. Upon reaching the set temperature, the bimetal disc deforms, breaking the circuit to prevent overheating. Once the temperature decreases, the disc returns to its original position, closing the circuit and restoring normal operation.

Functionality:

  • Over-temperature Protection: The bimetal disc deforms when overheating occurs, cutting off the circuit to protect the device.
  • Auto-reset: The thermal protector automatically resets once the temperature returns to a safe level.

This thermal protector is essential for applications that require reliable temperature management and protection against overheating.
