Arc Vault™ Protection System

DEH-41483 Rev. 3

Description

COMPARTMENT AREAS

The front enclosure of each section is divided into three

individual compartments. These compartments house

controls component, the Arc Vault™ device and the

optional Uninterruptable Power Supply compartment.

ARC VAULT COMPARTMENT

A standard Arc Vault compartment, Figure 3-2, is located

below the controls compartment.

Routine wiring inspections and fuse checks or fuse

replacements can be performed with the Arc Vault

compartment door in the closed position so that operators

are protected from the energized primary circuits.

An Arc Vault controls compartment, Figure 3-3, is available

as a standard feature. Internal hinged panels are used to

mount instruments and other devices associated with the

Arc Vault monitoring and control.

Relays and similar devices may be installed in the

compartment behind the swing-out device panel.

The Arc Vault compartment is a closed-door drawout

compartment. Figure 3-4 and Figure 3-5 shows standard

construction. The Arc Vault compartment doors remain

closed and latched while the Arc Vault is racked out from

the CONNECTED position, through TEST, to the

DISCONNECTED position.

Arc Vault compartment doors do not have any ventilation

slots, thus protecting operators from hot ionized gases

which may be vented by the Arc Vault during circuit

interruption. Additionally, the Arc Vault compartment is

enclosed by grounded steel barriers on the top, sides,

bottom, and front. In the back, a flame-retardant, track

resistant, glass-filled polyester base minimizes the

possibility of fault communication between compartments

to the bus.
