The occurrence of an arc flash is a serious fault within a power system. Its destructive impacts can lead to severe personnel injuries, costly equipment damage and long outages.

ABB offers a wide range of solutions to prevent and mitigate the effects of arc flash events, thus enhancing safety, minimizing damage and reducing downtime.

Because safety is not a cost, it is an investment.

Arc flash mitigation solutions are essential because they save lives. But that’s not all. Taking the right precautions today can save you time and money in the future: protecting people and assets, reducing the cost of injuries and damage, limiting downtime and maintenance requirements.

Maximum protection

Maximum uptime

Maximum peace of mind

Protect personnel with solutions ranging from passive protection to ultra-fast arc mitigation solutions. ABB’s portfolio provides enhanced future proof solutions exceeding the requirements of the current regulations.

ABB's arc flash mitigation solutions keep your business running, improving uptime by limiting the energy of arc faults, therefore limiting the damage they cause to switchgear and assets and the repair time required.

You can count on ABB to have a solution that’s right for you –our range covers active, passive and preventive solutions from low- to medium-voltage applications. Our high quality solutions won’t let you down.

Safety, a priority for ABB, is built into every transfer switch solution we make. Available safety features include mechanical isolation of unsynchronized power sources, manual emergency operation, and protection from current-carrying parts to reduce the risks for operator injury.

Design principles

There are three design philosophies which protect operator and equipment in the event of an arc flash incident, one or more may be adopted within the same switchgear.

Passive arc flash protection solutions

Switchgear designed and tested to mechanically withstand the electric arc. Protection is afforded

by the containmentof the arc within the switchgear. Passive solutions also include advanced switchgear

design features to reduce the probability of an arc flash occurring,

Active arc flash mitigation solutions

Switchgear equipped with devices and solutions to limit the arc incident energy and consequently limit the damage to the equipment.

Preventive arc flash protection solutions

Switchgear equipped for remote operation, so that standard operations such as switching, diagnostic and operational monitoring, racking in/out, etc. can be conducted outside of the dangerous arc flash exposure area. Preventive solutions also include the predictive maintenance of assets
