BW & BH series thermostats provide reliable protection against over-current and over-temperature conditions. These units are firmly sealed, feature small internal resistance, operate silently, and reset automatically. When current passes through the temperature and current-sensitive bimetal, abnormal conditions cause the bimetal to change state, either cutting off or switching on the circuit. BH series offer enhanced safety compared to standard protectors, with no temperature effect lag during sudden high-current conditions.

BH series thermal protectors serve as effective, reliable security protection and alarm devices. They are 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 3.5MPa pressure are suitable for built-in installation in plastic coated motors.

H20 and H21 series universal and enhanced protectors feature large metal casings and consist of thermal conductive metal casing, bimetallic components welded with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat resistance cables. During abnormal operation, when environmental temperature reaches 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.
