Overview
PowerSafe Pro sets a new standard in safety and size. It offers important new features: locking connection covers, shunt-trip- protected doors that can lock connection covers in place while output power is present, and lockout/tagout brackets.
PowerSafe Compact offers safety in a smaller size. This model does not include the connector chamber, dual neutral, tie-off, LED worklights or support for 400 A capacity, which allows the PowerSafe Compact model to be more compact.
A fault-current-limiting option provides additional safety in the event of a short circuit, allowing safe connection of equipment with lower SCCR (Short Circuit Current Rating) and reducing arc-flash hazard.
