ACCESSORIES
Factory-installed Accessories
QOU circuit breakers and QYU supplementary protectors can be supplied with electrical accessories
factory-installed. Available factory-installed accessories are shown in Table 5 below. Each QOU circuit
breaker or QYU supplementary protector can be equipped with only one (1) factory-installed electrical
accessory from the table below. These devices cannot be added, modified or removed once
assembled. All electrical accessories occupy one additional pole space, 3/4 in. (19.05 mm). The proper
suffix number must be added to the circuit breaker catalog number to order an accessory.

Shunt Trip
The shunt trip accessory is used to trip the circuit breaker from a remote
location by using a trip coil energized from a separate electrical source.
When energized by a push button or other pilot device, the shunt trip
causes the circuit breaker to trip. The handle moves to the tripped position
and the Visi-Trip indicator appears. The trip coil has a coil clearing contact
to break the coil circuit when the circuit breaker trips. Shunt trips operate at
75% or more of rated voltage. See the wiring diagram in Figure 6.
