BW & BH series protectors offer reliable protection against over-current and over-temperature conditions. These sealed units feature small internal resistance, no noise operation, and automatic reset functionality.
When current passes 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 provide enhanced safety compared to standard protectors, as they eliminate temperature effect lag during sudden high-current conditions.

BH series thermal protectors serve as effective and reliable security protection and alarm devices, widely used in various applications including:
These protectors prevent damage from over-current and over-heating caused by abnormal operating conditions. Enforced types capable of withstanding pressures up to 3.5MPa are suitable for built-in installation in plastic coated motors.

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, as environmental temperature increases to the set value, the bimetallic components perform quick action, opening the contact points and disconnecting the circuit. When the device cools to safe operating temperature, the contact points automatically close and normal operation resumes.
