AIR CIRCUIT BREAKER
·, ' •
Type "DB" air circuit breaker i s designed to give
continuous and reliable service as the protective
link between the power source and associated pro­
ductive equipment. This breaker is built to operate
with
a minimum of maintenance, while at the same
""··
4
time its simplified construction permits maximum
accessibility for inspection and adjustment when
required. The ease with which attachments may be
added or removed is an outstanding feature of the
"DB" design.
For the greatest measure of safety to operating
personnel and also to minimize maintenance re­
quirements, the breaker should be mounted in an
enclosure suitable to local operating conditions.
A
selection of standard enclosures is available for
various applications.
•
Important:
To assure proper functioning,
inspect each breaker at reg11lar intervals in
accordance with a systematic maintenance
schedule. The frequency and character of the
inspections will for the most part be deter­
mined by the severity of the duty performed.
The minimum requirements, however, should
consist of a light monthly inspection, with
a
thorough inspection semi-annually. Occasion­
al checks on calibration
as
well as on coordina­
tion and freedom of all moving parts, must be
included in the maintenance schedule. Con­
sult Westinghouse engineering and service
personnel for recommendations pertaining to
special operating or maintenance conditions.
