Circuit Breaker Trainer Manufacturer,Supplier and Exporter in India
Product Code : EL-EPP-11353
Quick Answer: The Circuit Breaker Trainer works with a three-phase supply and load to show how common circuit protection devices perform, with four protection circuits whose fault current can be adjusted. An internal variable transformer sets and controls the fault current in each circuit.

Key Features
- Four protection circuits: fuses, magnetic-only, thermal-only and thermomagnetic circuit-breakers
- Each circuit has a contact breaker switched by an industrial discrepancy switch
- Circuit one adds an adjustable residual current detector, with digital display and switches to set earth leakage fault current
- Circuit two tests fuses and has a fuse break detector circuit
- Circuit three has remote and local control key switches for its contact breaker
- Internal variable transformer works with the load to set the fault current

About This Product
Students raise the fault current step by step in each circuit and compare how fuses and different breaker types respond. The residual current, fuse break and remote switching circuits show how earth leakage protection works and how a control room or remote operator switches a circuit in a real installation. Laboratories and colleges in Cyprus, Suriname, South Africa, Eritrea and Gambia can buy the Circuit Breaker Trainer through an export order.
Frequently Asked Questions
Which protection devices are on the Circuit Breaker Trainer?
Fuses, a magnetic-only circuit-breaker, a thermal-only circuit-breaker and a thermomagnetic circuit-breaker, one in each of the four circuits.
Does the trainer need its own supply?
It works with a suitable three-phase supply and load; an internal variable transformer then sets the fault current.
