Smarter safety
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.
Switchgear designed and tested to mechanically withstand the electric arc. Protection is afforded by the containment of the arc within the switchgear and the means to direct the arc gases and debris to a safe area. Passive solutions also include advanced switchgear design features to reduce the probability of an arc flash occurring.
Improve safety with our extensive portfolio of arc flash mitigation solutions including arc quenching and arc-resistant switchgear, Power Xpert XGIS switchgear, Power Xpert Dashboard, Power Defense molded case circuit breaker, Insulgard, arc flash relays and more.
Arc flash protection interrupts an arc at an early stage, with operation times as low as 1-2ms. Time is critical! In order to reduce the negative effects of an arc event, the arc clearing time must be reduced. This is the role of active arc flash mitigation solutions. Relays that detect the arc flash light and current (optional).
The principle of passive arc flash protection is based on the mechanical design of low- and medium-voltage switchgear. Robust design reduces the risk that a person, standing in front of switchgear with closed and latched doors, will be injured in the event of an arcing current event inside the equipment.
