POY Finalist: Arc flash system

Finalist in Safety in Plant Engineering’s 2011 Product of the Year competition


The Arc Vault system features an activation switch that can be used during routine maintenance to put the low-voltage equipment into a high-protection mode. When an arc flash event occurs, the system will send a signal to the arc containment device.

At the same time the decision to divert the arc is made, the system will also make a decision to open an upstream circuit breaker. This will turn off the system in approximately three cycles, at which point the arc in the containment system will terminate.
