Good   stability, measurement repeatability +/-1 °C

Temperature Range

60~160°C

45~140°C

Temperature Tolerance

+/-5°C

+/-5°C

Contact Configuration

Double pole   and single Throw type;

Two pairs   of composite silver nickel contacts have low contact pressure and unstable   contact resistance at low temperatures.

Single pole and single throw type;

A pair of   gold-plated silver nickel contacts with strong oxidation resistance and more   stable contact, especially suitable for low-voltage DC circuits.

Contact Resistance

9~15mΩ

8~12mΩ

Insulation Resistance

Insulation resistance between wire and insulator100MΩ  (DC500V)

Compressive Strength

Withstand   AC1500V between the wire and the insulator (leakage current: 5mA), lasting   for 1 minute without any breakdown or flickering phenomenon.

Moisture Resistance Test

Thermal protector is placed in a constant   temperature oven at 40 +/-3 °C and a relative humidity of 90-95% for 48   hours, and the insulation resistance between the wire and the outer cover is   above 10M Ω.

Durability

Under rated voltage and current conditions, thermal   protector can turn on and off normally after 10,000 actions of the product   caused by an external heat source.

External Pressure

Can   withstand plane pressure of 100N, no change in performance (Metal shell)

The plane   pressure should not exceed 50N    (Plastic shell)
