Afr-4 Cost-Effective 4 Channels Switchgear Arc
With a fast relay output speed up to 5ms, AFR-4 can minimize or
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.
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.
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).
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. Maximum peace of mind.
