Switch/Breaker (Consult factory for availability) Push-to-Reset Breaker Features • Switchable version combines on-off switch and circuit protection in a single unit. • Approved to many international standards (push to reset type). • Replaces slow blow glass cartridge fuse. • Labor-saving snap-in mounting. • Button extends for visual trip indication on push to reset model. • Rocker on switchable model moves to “overload” position upon trip. 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.

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 Mechanical/Environmental Data Endurance Cycling(switchable type): Typically 30,000 operations at 100% of rating. Termination: .250” (6.35mm) quick connects. Soldering to terminals is not recommended. Mounting: Snaps into panel from front. See Recommended Panel Cutouts. Approximate Weight: 0.35 oz. (10g). 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 .

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. www.tycoelectronics.com Technical support: Refer to inside back cover.
