Primary disconnect shutters
Primary disconnect shutters, Figure 23, are
equipped as a standard to provide protection
against contact with the energized stationary
primary disconnects when the breaker is removed
from its compartment.
The shutters are constructed from UL approved
flame retardant materials carrying a V0
flammability classification per UL 94.
1. Shutter assembly (open)
2. Primary disconnect stab tip (typical)
The shutters are closed when the breaker is in the
DISCONNECT Position. As the circuit breaker is
racked from the DISCONNECT Position to the TEST
Position the shutters remain fully closed. As the
breaker is racked from the TEST Position to the
CONNECT Position, the shutters open allowing the
breaker to connect to the primary disconnects.
Figure 24 shows the shutter assembly with the
shutter in the open position.
Danger:
Hazard of electrical shock or
burn. Turn off power to this
equipment before working inside.
