- Circuit breakers and circuit breakers guarantee safe switching off in the event of a short circuit and protect consumers and systems against overload, for example against damage to the electrical lines due to excessive heating as a result of an excessive electrical current.They are trained to automatically switch off a circuit to be monitored in the event of a short circuit or the occurrence of an overload and thus from the rest of the line network Circuit breakers and miniature circuit breakers are therefore used in particular as switching and safety elements for monitoring and protecting an electrical circuit in electrical energy supply networks Filters are known in principle from publications DE 10 2015 217 704 A1, EP 2 980 822 A1, DE 10 2015 213 375 A1, DE 10 2013 211 539 A1 or EP 2 685 482 B1.
- a single-pole circuit breaker is usually used, which is usually one pitch unit wide (corresponds to approx. 18 mm).
- three-pole conductors protective switches are used, which accordingly have a width of three pitch units (corresponds to approx. 54mm).
- Each of the three phase conductors has a pole, i. H . assigned a switching point. If the neutral conductor is to be interrupted in addition to the three phase conductors, this is referred to as a four-pole device, which has four switching points: three for the three phase conductors and one for the shared neutral conductor.

- a residual current circuit breaker is a protective device to ensure protection against a dangerous residual current in an electrical system.
- a residual current which is also referred to as residual current—occurs when a live line section has an electrical contact with earth. This is the case, for example, when a person touches a live part of an electrical system: in this case, the current flows as a fault current through the person's body towards earth. To protect against such body currents, the fault current circuit breaker must quickly and safely disconnect all poles of the electrical system from the mains when such a fault current occurs.
- FI circuit breaker (abbreviated: Fl switch), residual current circuit breaker (abbreviated: DL switch) or RCD (for "Residual Current Protective Device") are equivalent used .

- arc or AFD units are used to detect arcing faults that can occur at a defective point in an electrical line - for example, a loose cable clamp or a broken cable. used . If the accidental arc occurs electrically in series with an electrical consumer, the normal operating current is generally not exceeded because it is limited by the consumer. For this reason, the accidental arc is not detected by a conventional overcurrent protection device, such as a fuse or a circuit breaker. To determine whether an arc fault is present, the arc fault detection device measures both the voltage curve and the current curve over time and analyzes and evaluates them with regard to the curves that are characteristic of an arc fault.
