5-4 CONNECTION DIAGRAMS
Connection Diagrams for all circuit breakers are shown
in Figures
5-7
through
5-13.
5-4.1 TIMING
The opening and closing times for the circuit breakers
vary depending upon the control voltage and the power
rating. Typical values for VCP-TL and VCP-TRL
breakers are given below:
Closing Time
(from initiation of close signal to contact
make) - 60 milliseconds
Opening Time
(from initiation of trip signal to contact
break) - 25 to 38 milliseconds
Re-closing Time
(from initiation of trip signal to
contact make) - 250 milliseconds
5-4.2 SECONDARY CONNECTIONS
Each secondary wiring point is identified and dedicated
to a specific function. The wiring points are finger safe
with no more than two wires per terminal. Two male
type secondary plug-in connectors are mounted on the
top rear portion of the circuit breaker. The plug-in
connectors are protected by a molded hood. When the
front cover of the circuit breaker is removed, the top of
each plug-in connector is exposed. A label on each
connector identifies the wiring points (Figure
5-14
).
There are two secondary connection options for fixed
type VCP-TRL circuit breakers:
(1) Standard Secondary Disconnect Block - The
secondary disconnect block is a female connector with
male pins compatible with a male connector with female
pins mounted under the protective hood (Figures
5-6
and
5-15
)
.
The customer plugs secondary wiring with
crimp-on connectors into the back of the female plug-in
connector.
(2)Optional Screw Type Terminal Block - For those
customers preferring to wire to a terminal block, an
optional screw type terminal block is available for
terminating the secondary wiring leaving the female
secondary disconnect block. The terminal block is
available in kit form (Figure
5-16
)
.
Drawout type VCP-TL circuit breakers utilize an
umbilical cord utilizing a male connector with female
pins on the breaker end and a female connector with
male pins on the cassette end. One end plugs into its
matching connector mounted under a protective hood
on the front.
top portion of the circuit breaker. The other end plugs
into its matching connector mounted under the front
top portion of the drawout cassette.
A standard tool is available from the plug-in connector
manufacturer (AMP) to facilitate the removal of
secondary wring from the plug-in connector (Figure 5-
17). The connector halves must be separated to use
this tool.
