How thermal overload relay works
NettetPengertian Thermal Overload Relay. Thermal Overload Relay adalah sebuah aksesoris komponen pengaman pada kontaktor utama atau pelindung saat terjadinya arus yang … NettetThermal Overload-Relay works on the principle of thermal expansion, i.e., as the relay detects an increase in temperature and expands, it is pulled out of the mounting base. Thus, it releases contact from push-on contacts that close when …

Simple Operation. One of the many advantages of thermal relay devices is their simple operation. This is because they are designed to operate using only a few simple components, such as heaters and bimetallic strips. This makes them easy to install and reduces the need for additional wiring and complex mechanisms.
Nettet18. sep. 2006 · The Magnetic Overload relay has a movable magnetic core inside a coil which carries the motor current. The flux set up inside the coil pulls the core upwards. When the core rises far enough (determined by the current and the position of the core), it trips a set of contacts on the top of the relay. Nettet9. aug. 2016 · A bimetallic overload relay consists of a small heater element wired in series with the motor and a bimetal strip that can be used as a trip lever. The bimetal strip is made of two dissimilar metals bonded together. The two metals have different thermal expansion characteristics, so the bimetal strip bends at a given rate when heated.
NettetThermistor relays can be useful in all applications where motors are used especially where overloads are frequent and may cause motor damage: pumping stations, water treatment, conveyors, material handling, HVAC, and chillers. etc. The characteristic of a resistor is not influenced by harmonics.
