Circuit Breaker Trainer Manufacturer,Supplier and Exporter in India

• A variable transformer inside the unit works with the load to set and control the fault current in each of four circuits. 
• Circuit two tests fuses and includes a ‘fuse break’ detector circuit. 
• This uses lamps to show the students when each of the fuses breaks. 
• To show students how industrial switching circuits work, each circuit includes a contact breaker, switched by an industrial standard discrepancy switch. 
• Circuit one includes an additional adjustable residual current detector for experiments with different residual current faults. 
• Each circuit has a different current protection device, including fuses, a magnetic only circuit-breaker, a thermal only circuit-breaker, and a thermomagnetic circuit-breaker. 
• It includes a digital display and switches to help set the earth leakage fault current before the test. 
• It shows the fault current and breaking time relationship for different fuse types. 
• Circuit three also includes remote and local control keyswitches to switch its contact breaker and break the circuit.
• This helps to show how both a control room operator or a remote operator can switch a circuit on or off in a real installation.
