ST01 Series High Temperature Thermal Protector(200~250°C)

$200.00

Key Benefits:

  • The first China-made round shape thermal protector and broke 30 years’ monopoly of German protectors.
  • It can prevent product failure from the vacuum impregnation process.
  • Small in size and suitable to be embedded inside the coil of electric motors.
  • With a metal case can bear up to 50KG coil shaping pressure, which has high thermal conductivity and temperature sensitivity.
  • Pure temperature action type products, bimetal-disc without current and heat effect, accurate temperature control.

Description

Applications:

• Electric motors
• Transformers
• Coils
• Electric heating appliances

 

Integration of Resources:

  • The spring material comes from Japan NGK and is manufactured by a Japanese stamping supplier.
  • The case and spring adopt silver plating technology, which greatly reduces the contact resistance.
  • The key components bimetal-disc produced by fully automatic forming equipment, separated by tunnel furnace separation equipment, with good consistency and stable performance.

Advantages:

Contact: Silver-nickel alloy, with long lifetime, over-current capability
  Spring: Beryllium copper imported from Japan, with good elasticity
 Case: Metal case, better thermal conduction, precision control within 0.02mm, the thickness of silver plated on the surface up to 3um
