Auto Reset Button Type S01 S02 Coil Transformer Protector Bimetal
Motor Thermal Protection Switch
S01/S02 Button type is snap action and bimetallic thermostat.
Bimetal trips off or on quickly to open or close the circuit when
temperature reaches the prescribed value.

Performance
The Max tripping electrical parameters
250VAC 3A / 127VAC 6A, 12VDC 6A / 24VDC 5A.
The tolerance of action temperature:±5℃, the reset temperature
according to actual
setting requirements.
Insulation voltage: The thermal protector can should be able to
withstand AC1500V,
1min or AC1800V,1s between lead wire and insulation sleeving, no
breakdown
flash-over phenomenon, the leakage current should be below 1mA.
Insulation resistance: Under normal conditions, the insulation
resistance between lead
wire and insulation sleeving is more than 100MΩ(The meter used is
DC500V insulation
resistance gauge).
Contact resistance: The contact resistance of thermal protector
should be less than
50MΩ.(Or customized)
Heat resistance test: The product is placed within 150℃ environment
for 96 hours;
Humidity test: The product is placed at the 40℃ environment with
the relative humidity
of 95% for 48 hours.
Drop test: the product drops freely once from a height of 70cm to
the ground(plastic or
wood floor).
Life Cycles
Under the conditions of the rated voltage, current and power factor
of 1, a heat source is
added to the product to make it move for 2000 times, which should
meet the following conditions:
A: The action temperature should change within ±5℃ of the initial
value;
B: The contact resistance should be less than 50mΩ;
C: No welding or shedding of electrical contacts;
D: After the product continues to be tested for 10,000 times, its
action to be normal and
correct.
Special Features
Small size and easy for mounting;
Low current sensitivity;
Precise temperature control.
Application
Electrical tools, motors.
Transformer, ballast.
Coil.
Model Definition Specification and Size
Packing Storage and Transportation
Product packing adopt sealed plastic bags, shipped carton
packaging.
The product should be stored at the -5~40℃ environment with the
relative humidity of
40~80% for 12 months, without changes.
Direct transportation or shipment, it should be handled carefully
and avoid collision or damp.
Temperature Protection Principle
The current flows the case terminal and bimetallic strip, then the
bottom board
terminals is connecting to application(such as motor and
transformer etc.) in circuit, when the
application works abnormally, which causes the ambient temperature
to exceed the setting
value, the thermal protector cut the power off ,when the ambient
temperature will decrease and
then the protector will close again.
