17AMI series motor thermal protector construction:

1,17AMI series are overcurrent and thermal protector products,small size and quick response,it
has been widely used in precise controlling of temperature limited or current limited
components in motor,transfomer etc.

2,17AMI thermal protector products's principle:current following through the bimetal strip and
two contacts,when an electric appliance under non normal work status,the temperature or current
reach the max limitation for OFF,the bimetal strip will break off immediately and cut off the
circuit.When the electric appliance back to normal temperature the bimetal will close
immediately and connect the circuit.This thermal protector has automatic reset function.

3,17AMIOP series products are added PTC based on 17AMI.The power-off protection and delay
protection effect,this type requires cut off the circuit then reset to work status,with
reliable and safe characteristic.


4,17AMIRP series products are added thermal compensation resistor based on 17AMIOP which original
type is manual reset,this provide a precise overcurrent protection.This type could be adjusted
based on customer's different current or time requirements,this type also requires cut off the

circuit then reset to work status,with reliable and safe characteristic.
