selection. For electrical ratings of disconnect
and circuit breaker interlocks, see
Table 16.107 below.
Accessories
Interlocks and Control Transformers
An electrical interlock may also be factory
installed in either a disconnect switch or
circuit breaker combination starter. Specify
Form Y74 for single pole, or Form Y75 for
two pole interlocks. For pricing see factory
modifications (Forms).
A one or two pole electrical interlock can be
added to the disconnect switch or circuit
breaker. Thus, if a separate control circuit is
used, the magnetic starter can be
de-energized when the disconnect is
switched to the OFF position.
See Table 16.106 for proper interlock

These 100 VA kits are designed specifically to allow for field modification
of NEMA Size 0, 1 and 2 combination starters that require a control
power transformer. The kit includes a 9070TF100 fused transformer on
a special mounting plate for ease of placement and installation on the
combo starter back pan. A wire harness (with wiring diagrams) is
included to complete the kit.

Internal Auxiliary Switch—Circuit breakers can be supplied with a
factory installed auxiliary switch for remote indication of an open and/or
tripped or a closed breaker. One (specify Form Y741) or two (specify
Form Y751) auxiliary switches can be supplied. The switches are
supplied with normally open and normally closed circuits with a common
connection. Contacts must be used on the same polarity and are rated
15 Amps at 240 Vac. The auxiliary switches are located internally and
are furnished with 19-20 inch long leads.
Alarm Switch—The alarm switch only operates when the breaker is
tripped. It is used to actuate bell alarms and warning lights. The alarm
switch is factory installed only (specify Form Y742) and consists of a
single pole single throw switch which is normally open except when the
breaker is tripped. The contacts are rated 4 Amps at 240 Vac. This
switch is located in the breaker and is supplied with 19-20 inch long
leads.
Transformer Selection—Space and drilling are provided in all
disconnect switch and circuit breaker combination starters in NEMA 1, 4
& 4X stainless and polyester, 12 and 7 & 9 bolted enclosures for the field
addition (or factory installation) of a Class 9070 control circuit
transformer and Class 9999 Type SFR4 fuse holder. This kit can be
either panel mounted or side mounted on the Type S starter. For
standard control transformer selection in combination starters, see
Table 16.109. Consult field office for transformer additions to NEMA 7 &
9 SPIN TOP® enclosures. For secondary fuse holder order 9080PF1.
Fuse Block Mounting Brackets—The standard capacity transformer,
Class 9070 Type T100, for the Size 0 and 1 starters mounts to the right
of the magnetic starter.
Standards—Most combination starters and forms are UL Listed in file
E152395, Category NKJH, and CSA File CR 584.
