BH Series Thermostat - Principle and Structure
BW & BH series protectors provide protection against over-current and over-temperature conditions. They feature sealed construction, small internal resistance, no noise operation, and automatic reset functionality. When current flows through the temperature and current-sensitive bimetal, the bimetal's status changes in response to over-temperature or over-current conditions, either cutting off or switching on the circuit. BH series protectors offer enhanced safety compared to standard protectors, as they eliminate temperature effect lag under sudden high-current conditions.

H20, H21 Series Thermostat - Principle and Structure
H20 and H21 series universal and enhanced protectors feature large metal casings and are composed of thermal conductive metal casing, bimetallic parts welded with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat resistance cables. During abnormal operation, when environmental temperature increases to the set value, the bimetallic parts perform quick action, open the contact points, and disconnect the circuit. When the device cools to safe operating temperature, the contact points automatically close and normal operation resumes.
