ST01 U6

$200.00

Key Benefits:

The first China-made round shape thermal protector got UL, TUV and CQC certifications and broke 30 years’ monopoly of German protectors.
Thermal protection ST01 is in a well-sealed design，which can prevent product failure from the vacuum impregnation process.
Thermal protection switch is Small in size and suitable to be embedded inside the coil of electric motors.
motor thermal overload switch with a metal casecan 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
• Electronics, sensor

Integration of Resources:

Integrating global supply chain resources, we purchase bimetal discs from EMS, the world’s largest manufacturer of bimetal disc materials, and purchase cases from German suppliers that use stamping and forming technology.

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 of the bimetallic disareproduced 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
