The Differential Circuit Breaker is a special switching mechanical device that combines the capability of a circuit breaker and a residual current circuit breaker. Its distinctive feature is the ability to protect against short circuits and overvoltage, as well as against loss of electricity in the event of a defect in the insulation protection of the cable during human contact with a conductor that is energized.
How it works
The Difautomat works in much the same way as a conventional circuit breaker. If an overload occurs, the bimetallic plate is heated by the electric current passing through it. Also, the plate bends, and if the voltage in the circuit does not decrease, the disconnection system is triggered, which opens the protected circuit.
When a short circuit is formed, the current in the loop begins to increase and the magnetic field moves to the core, where the disconnecting device is activated and the power contact is opened.

Main functions of the device
Difautomats are necessary for:
- protection of one single device;
- protection of all wiring with a single mechanism;
- creating multilevel or complex protection.

What is the difference between an RCD device and a difavtomat?
The difavtomat protects not only itself, but also the circuit, the load from a possible short circuit, an increase in currents that may arise from an overload of the network.
