Device circuit breakers
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 electronic, thermomagnetic, and thermal technologies.
Optimize your production process and minimize downtimes by using our overcurrent protection.
Based on their function, 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:
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, as long as the overall process allows this.
