RS9700 thermal protector
Product introduction:
RS - 9700 type thermal protector can be divided into plastic shell thermal protector and iron shell thermal protector
Plastic shell thermal protector temperature can do: 50 ~ 130 ℃
Iron shell thermal protector temperature can do: 50 ~ 160 ℃
Shell have small shell and big shell, RS - 9700 - b for plastic shell, RS - 9700 a for metal shell;
Size: 20 x 7.5 x 4 mm
Size: 20 x 8 x 4 mm

A, product structure and performance features:
RS - 9700 type thermal protector using a bimetallic strip on the motor current products such as sensitive and start thermal protector action and reset device; Is a sealed structure of the device, can guarantee that the thermal properties in the work is difficult to change. With automatic reset, and multiple sexual use, stable and reliable performance, easy installation, the flow characteristics such as big.
Widely used in air conditioning plastic ?
Second, the safe thing:
(1), composite silver contact: composite material for silver cadmium oxide (Ag - cd012), the thickness of the composite was 0.20 mm. Work, make it through 5 ampere working current, contact breaking and closing 20000 times, thermal protector can still meet the insulation resistance not less than 2 m Ω requirements.
(2), temperature tablet: material for double metal (FPA721-110). Temperature tablet by rolling forming after heat treatment, its operating temperature and reset temperature should be in tolerance range, and the action form for transient dynamic type.
Three, technical parameters:
(1), electrical strength: thermal protector two contact disconnect, should be able to withstand 500 v basic sine wave, frequency 50 hz ac voltage lasted 1 min electric strength test, should not happen breakdown or flashover phenomenon.
(2), electrical properties: thermal protector in 250 v frequency 50 hz ac ?
