EntelliGuard
EntelliGuard G devices have provisions for four accessory
operating coils. The four positions can be filled by the following
four devices: one Close Coil (CC or CCC), one Shunt Trip Coil, one
UVR (Under Voltage Release), and the fourth position can either
be a Shunt Trip Coil or a UVR. The closing coil is a "one-shot"
electronic closed circuit. Shunt trip (ST) coils are continuous rated.
Under voltage relays (UVR) are available with a fixed time delay
(50ms at down to 50% system voltage; 20ms below 50% system
voltage). The time delay module (TDM) is available as a shipped-
loose accessory for remote installation (in equipment). Optional
status contact modules for the ST, CC and UVRs provide coil
status (energize/de-energize) via the secondary disconnects and
trip unit.
OPEN/CLOSED, ON/OFF indication is provided on the front cover.
Heavy duty, motor/gearbox unit; easily accessible with a full
range of voltages.
Located on the front cover between the Open and Close button;
used to electronically close the breaker when a Command Close
Coil is selected.
Provides visible indication/readiness for close operation.
Kits are available to mount and connect fixed/stationary breakers
in either a rear connected (Vertical) or a front flat connected.
Four available designs:
• Power rated (3NO+3NC) (Standard)
• Power rated (3NO+3NC) + low signal (Hi-Fi) (2NO+2NC)
• Power rated (8NO+8NC)
• Power rated (4NO+4NC) + low signal (Hi-Fi) (4NO+4NC)
Standard interlocks include:
• Drawout Breaker: prevents the breaker from being closed
unless it is in the TEST or CONNECT positions
• Drawout Breaker/Main Contacts: prevents withdrawal/removal
of the breaker unless the main contacts are OPEN. Access to the
drawout mechanism racking screw is blocked when the breaker
is CLOSED.
• Spring Discharge Interlock: Automatically discharges the
closing springs when the breaker is moved from the DISCONNECT
to the WITHDRAWN position. This prevents withdrawing a breaker
from the cubicle with the closing springs charged.
