Product Description
Auto Reset Thermal Protector Fuse - Metal Case Thermal Protection Switch
BH-A1D Series Thermostat Principle and Structure
The BH-A1D series provides protection against over-current and over-temperature conditions. These devices are firmly sealed, feature small internal resistance, operate silently, and reset automatically. When current flows through the temperature and current-sensitive bimetal, its status changes in response to over-temperature or over-current conditions, either cutting off or switching on the circuit. BH series protectors are safer than standard protectors, as they eliminate temperature effect lag under sudden high-current conditions.
