Circuit breaker positioning
The IZM drawout circuit breaker has four normal positions:
•
REMOVE (withdrawn) (Figure 7)
•
DISCONNECT (Figure 8)
•
TEST (Figure 9)
•
CONNECT (Figure 10)
The REMOVE position is a position outside the compartment
on the cassette’s drawout rails where the circuit breaker is not
engaged with the levering mechanism. The DISCONNECT, TEST,
and CONNECT, positions are reached by means of the levering
mechanism.
With the breaker solidly positioned on the cassette’s extension rails
and levering-in mechanism in the DISCONNECT position, carefully
and firmly push the circuit breaker into the compartment as far as it
will go. The outer (recessed) portion of the circuit breaker faceplate
should align with the GREEN target line (labelled DISC) on the inside
top-left wall of the cassette (Figure 11).
