Dimensioning and protection of control circuits
Whether robust electromechanics or highly sensitive electronics, all 24 V DC consumers are often supplied by a single regulated switched-mode power supply. To prevent faults at a single consumer from paralyzing the entire system, the control circuit is divided into individual branches and selectively fused.
- Requirements for the primary and secondary connection
- Reduced short-circuit current in the control circuit
- Tripping characteristics of miniature circuit breakers, circuit breakers for equipment and selectivity modules
