Above-standard safety pays off with digital circuit breakers

Modern circuit breakers offer reliable protection against overloading and short circuits in machines and systems. IEC/EN 60947 and UL 489 (for North America) specify the requirements for circuit breakers. However, there are now circuit breakers on the market which, thanks to their digital trip units, offer many additional functions that are not required by the relevant standards. For example, if a system cannot be switched off for maintenance work, the maintenance mode of the new digital circuit breaker NZM ensures that in the event of a fault, service personnel will only be exposed to the lowest possible amount of arc energy.

Our white paper shows how investment in a digital circuit breaker can pay off in more ways than one: They not only offer better protection for personnel against electrical accidents, but also reduce downtime, simplify maintenance and increase the efficiency of the entire system. This makes the white paper an interesting read for plant managers who want to enhance the safety and availability of their factories, as well as for machine builders and system integrators interested in boosting the competitiveness of their systems.
