Applications
The ST-22 thermal protector serves as an effective security device for various applications including:
  • 1.5 horsepower motors
  • Inverter welding machines
  • Switch power supplies
  • Fluorescent lamp ballasts
  • Electric appliances and equipment
  • Plastic coated motors (3.5MPa pressure-resistant models available)
Operating Principle
The H20/H21 series protectors feature a thermal conductive metal casing with bimetallic components welded to silver alloy contact points. During abnormal operation, rising temperatures cause the bimetallic components to quickly open the circuit. When temperatures return to safe levels, the contacts automatically close to restore normal operation.
