Agency Approvals

W28 series is UL 1077 Recognized as Supplementary Protectors, File

E69543, and CSA Accepted as Supplementary Protectors (Appliance

Component Protectors), File LR15734. W28 breakers have been

issued Certificate of Suitability CS2190N as supplementary

Equipment Protectors by the Energy Authority of New South Wales,

Australia. W28 breakers are also DEMKO (Denmark) and SEV

(Switzerland) approved. VDE approved for use in office equipment

(AC loads only) and provides 8mm isolation. 16 amp and 20 amp

models do not have VDE, DEMKO and SEV approvals at present.

Users should thoroughly review the technical data before selecting a product part

number. It is recommended that users also seek out the pertinent approvals files of

the agencies/laboratories and review them to ensure the product meets the

requirements for a given application.

To use this chart: Read up from the ambient

temperature to the curve, and across to find a

correction factor. Multiply the breaker rating by the

correction factor to determine the compensated

rating. Calculate the overloads in terms of the

compensated rating to use the published trip curve.

Do not use these devices outside their specified

operating temperature ranges.
