Product Description
H20 KSD9700 10 Amp Resettable Fuse KW9700 Thermostat H21 Bimetallic Thermostat
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. The bimetallic components respond to temperature and current changes, cutting off or restoring circuit connection as needed. BH series offer enhanced safety with no temperature effect lag during sudden high-current conditions.

Applications and Instructions
H21 series thermal protectors serve as effective, reliable security protection and alarm devices. They are widely used in:
- 1.5 horsepower motors
- Lighting devices
- Inverter welding machines
- Switch power supplies
- Rechargeable battery packs
- Fluorescent lamp ballasts
- Portable power tools
- Electric appliances and other electrical equipment
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.

Principle and Structure
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.
