Agency Approvals
W28 series is UL 1077 Recognized as Supplementary Protectors, File
E69543, and CSA Certified as 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 and provides 8mm isolation. 16 amp and
20 amp models do not have VDE, DEMKO and SEV approvals at
present. W28-S is UL 1077 Recognized, and CSA Certified for models
up to and including 15 amps.
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.
Electrical Data @ 25°C
Calibration: Will continuously carry 100% of rating.
3-20 amp models – may trip between 101% and 134%, but
must trip at 135% of rating within one hour at +25°C.
0.25-2 amp models – may trip between 101% and 174%, but
must trip at 175% of rating within one hour at +25°C.
Dielectric Strength: Over 1,500 volts RMS.
Maximum Operating Voltages: 32VDC; 250VAC, 50/60 Hz.
Interrupt Capacity: 1,000 amps at 250VAC, 50/60 Hz. and 32VDC in
accordance with UL standard 1077.
Resettable Overload Capacity: Six times rated current for 0.25 through 2
amp models. Ten times rated current for
3 through 20 amp models.
Reset Time: 180 seconds max. for 0.25 through 2 amp models. 10 to 60
seconds for 3 through 20 amp models.
