17AM1 series for high voltage motor overcurrent protection

17AM1 series Thermal Protectors deliver the SAME maximum protection as 17AM in the smallest package at a MUCH LOWER price. TOPRO 17AM1 series Thermal Protectors are miniature, light weight and sensitive to both temperature and current. The sealed steel cases will stand most dip and bake processes and can be mounted directly on motor windings for fast detection of temperature changes. Robust construction and ability to withstand typical mechanical pressures make TOPRO 17AM1 ideal for installation during the manufacture of electric motors and transformers.

Working Principle

This thermal protector will cut off the circuit automatically in case of overcurrent or overheat. 17AM1 thermal protectors use the same snap-action principle of KLIXON protectors. The bimetal disc senses both heat and current from the equipment which 17AM1 is installed on. When the temperature of the disc reaches a predetermined calibration point, the disc snaps open the contacts, thus breaking the current path. When the equipment returns to a normal operating range, the 17AM1 protector resets (closes circuit) automatically.

Temperature Code

Graphs

Differential of terms: thermal protector, thermal switch, thermal protection switch, temperature switch, Thermal Cut-out, temperature controller, thermostat 
The terms thermal protector, thermal switch, temperature switch, temperature controller and thermostat all refer to a mechanical device that contains a bimetallic strip sensitive to temperature and is therefore used to trigger a snap action when the temperature rises to a preset point. The snap action can cut off or put through power supply to control the protected device.
Thermal protector is the most standard term. As in most cases a thermal protector is used to protect the motor of a machine, such as vacuum cleaner, power tools, mower, washing machine, compressor, the thermal protector is often referred to as a motor thermal protector or a thermal motor protector. As the thermal protector can make or break the circuit like a usual switch, it is also called a thermal switch or temperature switch. Since they are made with the key component, a bimetallic strip, they are also called bimetal Thermal Switches. A thermostat or temperature controller is used to control the temperature within a certain range. Unlike the motor thermal protector, the thermostat and temperature is often used in a heating device. Literally, thermal protection switches are the same  as thermal protectors or Thermal Switches.
TOPRO 17AM1 Motor Thermal Protectors are the same in quality and structure as 17AM thermal protectors made by Klixon, but much lower in price.
