BW & BH series thermal protectors provide reliable protection against over-current and over-temperature conditions. These sealed units feature small internal resistance, operate silently, and reset automatically. When current flows through the temperature-sensitive bimetal element, abnormal conditions cause the bimetal to change state, either opening or closing the circuit as required.
BH series protectors offer enhanced safety compared to standard protectors, as they eliminate temperature effect lag during sudden high-current conditions.

ST-22 thermal protectors serve as effective and reliable security protection and alarm devices. They are widely used in:
These protectors prevent damage caused by over-current and over-heating during 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-resistant cables.
During abnormal operation, when environmental temperature reaches the set threshold, the bimetallic components activate quickly, opening the contacts and disconnecting the circuit. When the device cools to safe operating temperature, the contacts automatically close and normal operation resumes.
Certification Compliance: This product holds UL, CQC, TUV, and RoHS certification approvals.
