Description
Efficient Motor Thermal Overload Switch / Thermo Switch Protector For Floor Heating
The BW series thermal protector is designed for reliable overheating and overload protection in various electrical applications including floor heating systems.
Efficient Motor Thermal Overload Switch / Thermo Switch Protector For Floor Heating
Principle and Structure
The BW series thermal protector utilizes a geometrically designed bimetallic strip that directly senses heating current. Without auxiliary mechanisms, the bimetallic element rapidly changes state to automatically cut the circuit, providing reliable overheat and overload protection.
Applications
Widely applied in electric motors and electrical equipment including:
  • Electric blanket and hot wall systems
  • Washer motor, soybean milk machine motor
  • Fan motor, air conditioner motor
  • Fractional motor, direct current motor, AC brushless motor
  • Water pump, transformer, rectifier
  • Lighting systems, rechargeable batteries
  • Various electric heating appliances
Technical Specifications
  • Contact type: Normally closed and Normally open
  • Electrical rating: 10A/AC120V; 8A/AC250V; 10A/AC250V; 16A/AC250V
  • Circuit resistance: ≤50mΩ (Initial value)
  • Insulation resistance: ≥100mΩ
  • Action temperature range: 40~150℃
  • Case: Metal case and plastic case options
  • Life: ≥10,000 cycles
