5-6.2 INTERNAL ELECTRICAL ACCESSORIES
Other electrical accessories are mounted inside the
circuit breaker behind the front cover. Access to these
devices is gained by simply removing the front cover.
There are three internally mounted electrical
accessories:
Motor
Operator
Auxiliary
Switch
Trip Indicator/Overcurrent Trip Switch
Motor Operator -
A motor operator is a rugged electric
motor assembly internally mounted in the circuit
breaker (Figure
5-25
and Table
5.6).
It charges the
closing springs electrically for remote or local
operation. The motor operator can be factory or field
installed.
Manually operated circuit breakers are pre-wired to
accept the addition of an electrical motor operator in the
field. A UL listed motor operator kit is available for this
conversion.
Auxiliary Switch -
A 5a, 5b auxiliary switch is
supplied as standard on all circuit breakers for
customer use (Figure
5-26
and Table
5.7).
The switch
is a heavy duty, double break type switch with wipe
type contacts.
Trip Indicator/Overcurrent Trip Switch -
The
optional trip indicator is supplied on breakers ordered
with Digitrip RMS trip units. It provides a visual
indication, through a red pop-out plunger mounted
above the trip unit, that the electronic trip system has
initiated a trip signal. The trip indicator is reset by
pushing the plunger back into its normal position. The
trip indicator does not have to be reset in order to
operate the breaker or the trip unit.
The trip indicator is available with or without a SPST
overcurrent trip switch. This switch only changes
state with the trip indicator.
