AMT-C1 Bimetal Thermal Overload Protector , Hair Dryer Ceramic Temperature Switch

Product Description

AMT-C1 Series Bimetal Thermal Overload Protector Ceramic Temperature Switch for Hair Dryer

AMT-C1 thermostat is a hair dryer thermostat. Because the temperature sensor is in direct contact with the outside air environment, it has an overheating protection switch that is more sensitive and reacts faster. Its working temperature is fixed, no adjustment is required; it has the characteristics of reliable and crisp action, small arc, and long service life.
It is composed of highly sensitive bimetal components, shrapnel, moving contacts, static contacts, ceramic bases, etc. When working, the bimetal element is in a free state, and the moving contact and the static contact are in a closed state. When the electrical appliance generates heat due to a fault, and the temperature rises to the rated operating temperature of the product, the bimetallic element is heated to generate internal stress and quickly actuates the moving contact, disconnecting the contact and cutting off the power supply, and the electrical appliance stops working, thereby overheating Protective effects. When the temperature of the protected electrical appliance drops to the product's rated reset temperature value, the bimetal element returns to the initial state and the contact is closed, and the electrical appliance resumes work.

3.Exterior:
 The metal parts of the thermal protector shall not have burrs, cracks,
deformation, corrosion, etc.;
 The signs should be correct, correct and clear;
4.Performance:
4—1 Rated electrical:
 Rated current:AC220V/10A AC250V/10A AC125V/16A
4—2 operating temperature:Operating temperature: ±5℃/±7℃ (can be
adjusted according to customer requirements)
Remarks: A comparison table of temperature characteristics is attached
4—3 Contact resistance:When the contacts are closed, the contact
resistance between the two contacts of the thermal protector should
not be greater than 50mΩ.
4—4 Insulation resistance:
The insulation resistance is above 100MΩ.
4—5 moisture resistance
After being placed in an ambient temperature of 25°C and a relative
humidity of 95% for 10 hours, it meets the requirements of 4-4, and there
is no abnormal change in the appearance and structure. .
4—6 Circulation heating
Put it in the temperature of -20℃ and +90℃ every 2 hours, after 10
cycles, it meets the requirements of 4-4, and there is no abnormal change
in appearance and structure

4—7 Heat resistance
After being placed in a temperature of 130 ° C for 10 hours, it meets
the requirements of 4-4, and there is no abnormal change in the appearance
and structure..
4—8 cold resistance
 After being placed at -20℃ for 10 hours, it meets the requirements
of 4-4, and there is no abnormal change in the appearance and
structure. .
 The change of operating temperature is within 5℃.
4—9 Repeated opening and closing durability
At room temperature, after 2000 tests under the rated load conditions
of AC 50Hz, voltage 220V, and power factor COS∮=0.7, the rated operating
temperature should be within ±5°C of the initial value, and the contacts
will not be welded. Continue the test The thermal protector should still
work after 10,000 cycles.
4—10 Vibration resistance
For a fixed frequency test with a vibration frequency of 50Hz, an
amplitude of 0.35mm and a duration of 90min, the rated breaking temperature
after the test should meet the requirements of 4-2.
4—11 Drop impact resistance
 After being dropped from a height of 1200mm to the concrete floor
3 times at will, there is no abnormal change in its appearance and
structure.
 The operating temperature is within 5°C.

Instructions for Use

(1) Widely used in hair dryers, heaters, lamps, small household appliances.
(2) During the installation and use of the thermal protector, it is never allowed to touch the shrapnel and the temperature sensing part, otherwise it will cause the temperature of the protector to be inaccurate, poor contact and unable to work.

Features

(1) It can respond quickly to temperature changes and has an automatic reset function.
(2) There is no current through the bimetallic strip, which avoids the influence of self-heating effect
