■
Type 1 enclosed breakers are designed
for use in commercial buildings, apart-
ment buildings and other areas where
a general purpose enclosure is appli-
cable. The breaker is front operable
and is capable of being padlocked in
either the ON or OFF position. Ratings
through 1200 amperes are listed
with Underwriters Laboratories as
approved for service entrance applica-
tion. Both surface and flush mounted
enclosures are available.

This general purpose outdoor service
center employs a circuit breaker inside
a weatherproof sheet steel breaker
enclosure to serve as a main discon-
nect and protective device for feeder
circuits. Ratings through 1200 amperes
are listed by Underwriters Laboratories
as suitable for service entrance
application.

Type 12 Dustproof Surface
Mounting
■
■
■
The Type 12 enclosure is designed
in line with specifications for special
industry applications where unusually
severe conditions involving oil, coolant,
dust and other foreign materials exist
in the operating atmosphere. The handle
padlocks in the OFF position and the
cover is interlocked with the handle
mechanism to prevent opening the
cover with the circuit breaker in the
ON position. Ratings through 1200
amperes are listed by Underwriters
Laboratories as suitable for service
entrance application.
