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 confirm the product meets the requirements for a given
application.
Electrical Data
Calibration:
Breakers will hold 100% of rated current.
Breakers may trip between 101% and 124% of rated load (134% for AC/
DC units).
Breakers must trip at 125% of rated load and above (135% for AC/DC
units).
Dielectric Strength: 50/60 Hz., 1500V: DC, 1100V
Insulation Resistance: 100 Megaohms at 500VDC
Endurance:
10,000 on/off cycles - 6000 at rated load, 4000 at no load.
Units tested at six cycles per minute, 1 second on and 9 seconds off at
25°C ambient.

Mechanical/Environmental Data
Operating Temperature: -40°C to +85°C.
Humidity: Meets requirements of Mil-STD-202 method 103.
Shock: Tested per Mil-STD-202, method 213, test condition C
(100g @ 6 ms)
Vibration: Tested per Mil-STD-202, method 201, 10-55 Hz., 0.06”
(1.52mm) total excursion in 2 planes.
Mechanical/Environmental Data (continued)
Fungus and Moisture Resistance:
Special moisture resistant finish applied to all ferrous parts.
Plastic parts are made of inherently fungus resistant material.
Marking:
International “1” and “0” symbols are marked on the toggle for both W6 and
W9. W9 units have “ON” and “OFF” molded into the area at the base of the
toggle. On a special order basis, graphics can be imprinted on the rockers
of rocker actuated W6 units. VDE approved versions of rocker actuated W6
breakers have their rockers imprinted with “1” and “0”.
Mounting:
Units are mounted with two #6-32 screws from the front of the panel.
Metric models for use with M3 x 0.5 screws are available. To maintain
published performance specifications, units should not be mounted more
than 90° from their normal upright position.
Weight: Approximately 2.5 ounces per pole.
