Section 5: Dimensional drawings for
installation of drawout circuit breakers
General
Section 3 discussed topics and features common to all
series NRX circuit breakers, no matter what the mounting
configuration or type. In this section, features unique to the
drawout type circuit breaker and drawout cassette not cov-
ered elsewhere are discussed.
Drawout cassette
A drawout circuit breaker (Figure 2) is used in combination
with a drawout cassette (Figure 3). The cassette provides all
the necessary drawout circuit breaker interfaces, including
automatic primary and secondary connections. Standard
flat terminal pads on the rear of the cassette provide for
a variety of primary connection configurations.
Optional
primary adapters are available for rear bus connec-
tions.
For specific details and mounting instructions, refer
to IL01301053E. Refer to Figure 33 through Figure 47 for
selected mounting and installation dimensional information.

able from www.eaton.com/seriesnrx.
