Point Eight Power’s arc resistant metal-clad switchgear channels the energy released during an internal arc fault away from personnel and adjacent equipment into a vertical isolation plenum (VIP) where it is contained and vented safely.  For enhanced safety and security, our door designs feature a single action vault lock or slot lock system to provide automatic protection for the operator. 

Point Eight Power’s arc resistant metal-clad switchgear design undergoes thorough testing in order to  meet the ANSI accredited IEEE C37.20.7 standard.

Testing standards for arc resistant switchgear fall into two categories: Type 2B and Type 2C.  IEEE C37.20.7 defines type 2B equipment as that in which an arc event does not cause holes in the freely accessible front, sides, and rear of the enclosure or in the walls isolating the low-voltage control or instrument compartment(s).

Type 2C testing specifies that arcing does not cause holes in the freely accessible front, sides, and rear of the enclosure or in the walls separating the compartment in which the arc is initiated from all adjacent compartments.
