Device circuit breakers protect your equipment against overload and short-circuit currents and selectively shut down just the affected circuit in the event of a fault. To provide the ideal protection, our circuit breakers use various technologies: electronic, thermomagnetic, and thermal. Optimize your production process and minimize downtimes by using our overcurrent protection.

The product range of the TCP thermal circuit breaker is being expanded to include the new 16 A and 20 A variants. This means that loads with higher nominal currents can now also be thermally protected and switched off during maintenance.
Electronic and thermomagnetic device circuit breakers
Based on their function, device circuit breakers can be divided into the following groups:
Circuit breakers usually provide individual protection for equipment. In the event of an error, they shut down only the affected actuator or sensor in the faulty circuit.
This means that the production process continues running without interruption.
Based on their function, circuit breakers can be divided into the following groups:
| Tripping time in the event of overload | Tripping time in the event of a short circuit | Your application is optimally protected in the event of | |
|---|---|---|---|
| Thermal circuit breakers | Suitable | Unsuitable | Overload |
| Thermomagnetic circuit breakers | Suitable | Ideal | Overload, short circuit and long cable paths (thanks to SFB tripping characteristic) |
| Electronic circuit breakers | Ideal | Ideal | Overload, short circuit and long cable paths (thanks to active current limitation) |

Here is a brief explanation of the difference between miniature circuit breakers and device circuit breakers:
Miniature circuit breakers protect power distribution cables in buildings or systems. To protect the power supply line against overload, they safely shut down only in the event of a short circuit in the end device.
In contrast, device circuit breakers are the effective protection stage for end devices and protect against short circuit and overload. They can be optimally adapted to loads. For this reason, their nominal currents start at less than 1 A and they are subdivided into small current increments. If you protect individual loads or small function groups individually, unaffected system parts can continue operating in the event of an error, insofar as the overall process allows this.
