一、17AMI系列热保护器/马达保护器产品结构特点：
17AMI series thermal/motor protector construction:1、17AMI系列产品是一种过流过热保护器，其特点是体积小，断开动作快，用于精确的控制(电机马达、 变压
器...等电器)的限温、限流保护元件。
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热保护器工作原理：电流通过双金属片及两触点，当电器非正常工作发热高温达到热保护器设定OFF温
度值或电流过大超过正常工作电流时，双金属片迅速跳开，切断电路。当电器温度冷却到热保护器复归温度
时，双金属片又迅速闭合，电路接通。具有自动复位功能。
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系列产品是在17AMI自动复位的基础上加载了PTC热敏电阻，使其具有断电保护和延时保护的作用。需
要断电才能恢复工作，其保护功能更可靠，更安全。
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系列产品是在17AMIOP手动复位的基础上加载了热补偿电阻发热丝，使其具有更精准的过流断电保护
功能，可依据客户的需要设置不同电流和时间的保护要求，同样要断电才能恢复工作，其保护功能更可靠，
更安全。
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.
