BH-B2D Series Thermostat Principle and Structure
BH-B2D series thermal protectors provide protection against over-current and over-temperature conditions. They feature a sealed construction, small internal resistance, no noise generation, and automatic reset functionality. When current flows through the temperature and current-sensitive bimetal element, the bimetal changes state 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.
