The BW-ECP Thermal Protector from the BW-E series is a reliable 2A power class component designed to protect electrical equipment from overheating. This normally closed thermal switch automatically resets once the temperature returns to a safe level, ensuring continuous protection and seamless operation. The device is constructed with a plastic shell insulation, enhancing safety and durability. Key features include:

  • Power Class: 2A
  • Type: Normally closed (NC)
  • Reset: Automatic reset function
  • Connector Cables: Pre-attached for easy installation
  • Insulation: Plastic shell for electrical safety

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 sheet and then to the iron bracket. The stationary silver contact and base are molded as one unit. The electrical circuit is completed by the bimetal disc, which allows current to flow between the moving and static contacts. When the operating temperature is exceeded, the bimetal disc deforms, quickly breaking the circuit and stopping current flow. As the temperature cools down, the disc returns to its original shape, closing the circuit again.

Functionality:

  • Over-temperature protection: The bimetal disc rapidly deforms when a predefined temperature is reached, opening the circuit and preventing overheating.
  • Auto-reset: The disc snaps back into place when the temperature lowers, allowing the circuit to close and resume operation.

This thermal protector is ideal for use in applications requiring reliable, automatic temperature control.
