Accessory devices
A variety of accessory devices are available for use with Series NRX
circuit breakers. Unless otherwise stated, they are all considered
optional devices in the sense that they are not provided as standard
on a manually operated circuit breaker. Available accessories are
discussed in general terms. For more detailed information and/or
installation instructions, refer to individual instruction leaflets dedicated
to individual items.
Series NRX circuit breaker accessories are designed to be plug-and-
play and can be field installed. The accessories fall into one of three
categories:
•
Accessory tray devices
•
Other internal electrical devices
•
Mechanical devices
Accessory tray devices
Certain accessory devices are mounted in a mounting tray. The tray is
then installed in a left- or right-hand slot located in the upper left- and
right-hand sides of the circuit breaker (
Figure 30
and
Figure 31
).
