recommended that the breaker be cleaned and
inspected on an annual basis.

switch & bell alarm switch; For a 1 pole there are no
accessories; Installation of an accessory in a 2 pole
breaker is the same as a 3 pole breaker.

in connection with installation, operation, or maintenance. Should further information be desired or should particular problems arise that
are not covered sufficiently for the purchaser’s purposes, the matter should be referred to the ABB Company. The breaker is a sealed unit,
which contains no user serviceable parts, tampering with seal will void warranty.
