2) Lubrication
!
CAUTION
Before applying any type of lubrication to the
circuit breaker, the stored energy mechanism
should be in the open position, and all springs
should be discharged.
Powell offers a complete lubrication kit
(Powlube-104) which contains all the
lubricants required for maintaining the
circuit breakers. Powlube-104 consists
of (1) A-grease, (1) B-grease, and (1) C-oil.
Prior to March 2014, Powell provided
Powlube-101 and Powlube-102 which
contained (1) tube of Anderol 757 or
Rheolube 368A, (1) tube of Mobilgrease 28
and (1) bottle of Anderol A456 oil.
A – Grease should be lightly applied to
those bearing surfaces that are accessible.
Inaccessible surfaces, such as bearings, may
be lubricated with a light synthetic machine
oil such as C - Oil. B – Grease should be
applied to the electrical contact surfaces.
Lubricate the stored energy mechanism
and other specified parts in accordance
with
. See
for labeled lubrication photographs.
lists the location of all
surfaces that should be lubricated, the type
of lubricant to be used, and the method of
applying the lubricant. The guiding rule
in lubrication is to lubricate regularly, use
lubricant sparingly and remove all excess
lubricant. There is no need to disassemble
the mechanism for lubrication. Tilting the
circuit breaker will enable the lubricant to
cover the bearing surfaces.
