Genera l Req uirements
Circuit Breakers shall be of insu lated case construction. They
shall be UL Listed u nder Sta ndard UL 489, UL 489-S B2, CSA
Certified, and I EC 947-2 Certified and shall meet the require­
ments of N E MA Sta ndard AB1.
Circuit breakers shall be (manua l ly) (electrica lly) operated,
(drawout) (stationary) mounted with features and accessories
described in these requirements. Breakers shall have a mini­
mum voltage rating of 600 Vac, and shall be rated to ca rry
100% of the current rating of the b reaker continuously.*
Breakers shall have minimum UL Listed interrupting rati ngs
as indicated on the d rawings. All manually operated breakers
shall be field convertible to electrical operation by means of
the addition of an i nternally mounted electrical operator. Ad­
dition of an electrical operator shall not change the physical
dimensions of a b reaker.
Circuit breakers shall be constructed of a hig h-strength,
glass-reinforced insul ating case. Construction shall provide a
double level of insulation between primary current-carrying
parts and operating personnel. The interrupting mechanism
shall contain a rc chutes with steel vent g rids to suppress a rcs
and cool vented g ases. I nterphase barriers shall be included
to completely isolate each pole. For each breaker, the close
and latch rating shall be equal to its short-time rating to help
assure selectivity with downstream devices when c losing
into a fa ult.
Breakers shall contain a true two-step stored energy operat­
ing mechan ism p rovidi ng quick-make, quick-break operation
capable of charging-after-closing operation. It shall be pos­
sible to discharge the closi ng spring without closing the main
contacts. The m aximum closing time shall be three cycles at
nominal voltage.
Attem pting to close a circuit b reaker while an accessory un­
dervoltage release i s de-energized or, while a shunt trip with
lockout is energized, or while a bell alarm with lockout is ac­
tivated, shall result in a "kiss-free" operation of the contacts.
Common tripping of a l l poles shall be sta ndard. Breakers
shall be capable of a minimum of 10,000 mechanica l open
and close operations without any req u ired service.
When d rawout brea kers a re in the ful ly withdrawn position,
there shall be provisions for ti lti ng the breakers for inspec­
tion, maintenance or removal. It shall be possible to replace
the primary disconnect fingers with the breakers in the
withdrawn position.
Each breaker shall include a retractab le charging handle,
close pushbutton, open pushbutton, closing spring charge/
discharge indicator and b rea ker ON/OFF ind icator mounted
on the front of the breaker. Each breaker shall have as stan­
dard, a pad locking p rovision to prevent closing the breaker
when padlocks a re insta l led. Padlocking provisions shall ac­
cept up to three pad locks with 1/4" to 3/8" diameter shanks.
This provision shall meet OSHA and California Code (EUS ERC)
requirements.
Each stationary and d rawout b reaker shall have provisions
for up to 72 ded icated secondary term inal poi nts. All discon­
nected points shall be capable of being p robed from the
front of the breaker. All breaker control and accessory wiring,
including wiring for future accessories, shall be pre-wired to
i nteg ral terminal blocks which shall be clearly identified by
num ber and function. Each terminal point shall have space
available for two AWG#18#1 2 wires per terminal and cus­
tomer circuit identification.
Each circuit brea ker shall conta in the following accessories
(shunt tri p with or without lockout) (undervoltage release)
(bell alarm) (bell a larm with lockout) [ (4 or 8 or 12 stage) SPDT
auxiliary switches] (remote close solenoid) ( remote "charged"
indicator). All a ccessories shall be field instal lable. Field instal­
lation of sh unt trip (with or without lockout), undervoltage
release, bell a larms - with and without lockout shall require
no adjustments, no interna l wiring and no removal of the
circu it breaker cover. The be l l a l a rm and bell alarm with
locko ut shall each contain a mechanical target , which shall
extend from the front cover when the device operates. The
bell alarm (alarm only) shall reset a utomatica l ly when the
breaker is closed. The bell alarm with lockout m ust be reset
by dep ressing the mechanical pop-out target before the
b reaker can be closed. The bell alarm and the bell alarm with
lockout shall be independently fie\d-config u rable to operate
in response to an overcurrent and/or protective relay opera­
tion, plus any com bination of sh unt trip and/or undervoltage
release operation - including no response to a p rotection
trip, sh unt tri pping or undervoltage release trip. N ote: for the
Power+™ tri p u n it , the bell alarm and bell alarm with lock-
out respond to an overcurrent operation only. The shunt trip
(with or without lockout) shall be continuously rated with no
requirements for a cut-off switch.
Each c ircuit bre a ker shall conta in the fol lowi ng mechanical
accessories (operation cou nter) (sealable limited access "ON"
and "OFF" push button cover)
interlock provision ] (shutters to cover drawout/stationary
primary discon nects when the breaker is racked out) ( racking
padlock provision to prevent operation of the breaker racking
mechanism) (door interlock with defeat mechanism to pre­
vent opening the hinged breaker com partment door when
the brea ker is closed) (walking beam i nterlock for stationary
b reakers to prevent two a djacent breakers from being on
the same time) ( mechanical interlock for drawout b reakers
to prevent two adjacent b reakers from being on at the same
time). All mechanical accessories shall be capable of being
field i nsta lled.
