I.e example " if we have a shunt trip coil which is operate on 220 volts, so we need to provide the 220 volts AC current to shunt trip coil to operate or to do trip the breaker in emergency time. So we need to provide the supply / current to the shunt trip device circuit breaker when the emergency moments come. In EPO switch we have four terminals in which tow are Normally close with each other and other two are normally open. We use a push button switch for shunt coil which we know with it's short name "EPO" which i discuss in my above words. And the answer is that "it's also too simple".

You can find out the rate coil label on shunt coil, circuit breaker or on shunt trip coil.īut the question is that how to wire it. But you must provide the power source regarding coil rated volts. Now lets how to wire shunt trip device (accessory), it's too simple as i shown in above shunt trip device images that a shunt coil have only to wires, just like a magnetic contactor or magnetic relay coil. Here is some images of shunt coils and after that we will discuss the shunt trip breaker wiring diagram with image + symbol diagram. The shunt trip coil rod push this point internally when the shunt coil is operate. In the MCCB circuit breaker, we have a push able button or place which is named with "push to trip" and when we switch on the breaker and push this button the breaker become switch off and trip due to pushing this button.
The shunt trip move able rod hit the tripping point or disconnecting point of circuit breaker internally and the breaker become off or trip. In the coil a move able rod is fixed with spring and when we provide the supply
In simple words, a shunt trip a electromagnetic coil which make magnetic field by providing external power source. However is this post shunt trip breaker wiring diagram i shown only one EPO button and INSHALLAH in next post i will show you instillation of multi EPO (emergency power off) buttons for a single shunt trip MCCB breaker. One thing more that we can instill more then one EPO buttons for one breaker and every button will work same. In the advantages of shunt trip breaker, a most important things is that we can instill the emergency switch (EPO) anywhere, from where can easily push button or where the push button is near to us. If we comparison it between switching off the main circuit breaker then it's will get more time. Now if a short circuit is done in electrical instillation or other electrical accident, the operator can easily push a small push button switch and the all electric power supply will powered off. In industrial state, Electric operator duty is to operate the machinery and his duty is on the front of Main panel board.
In this post i am just tell you about wiring of single EPO button with shunt trip MCCB breaker. Shunt Trip Breaker Wiring Diagram with EPO Button. But When it's come to high load places or where we use the three phase supply then use a MCCB (module case circuit breaker) Shunt trip circuit breaker with emergency push button switch which we know better with name of EPO (emergency power off) button. In Single phase wiring or house wiring we use electric power supply between phase and neutral which can be control by using a simple double pole RCD Breaker. As you that mostly we use 3 phase system in industrial state where we can not protect our electrical distribution using RCD (residual current device).

As you know that electricity is dangerous but it's become more dangerous when it's upgrade from the 220 volts to 3 phase 440 volts. Today i am writing about shunt trip breaker wiring diagram which related with safety and protection of electricity. As you know that Safety is important in electricity works.
