Agency Approvals
UL: Recognized as Supplementary Protector under UL 1077. File
E69543.
CSA: Certified as a Supplementary Protector. File LR15734.
VDE: Approved to VDE 0642/EN 60 934 (Circuit Breakers for Equipment)
License No. 73782.
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.
Fungus And Moisture Resistance: Special moisture resistant finish
applied to all ferrous parts.
Plastic parts are made of inherently
fungus resistant material.
Marking: W6 units have ON and OFF molded on the rocker of rocker
actuated units (rocker actuated VDE units have international
“1” and “0”). W9 units have ON and OFF molded into the area
at the base of the toggle. International “1” and “0” symbols are
marked on the toggle for both W6 and W9.
Mounting: Panel mounted 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. Units with snap-in mounting option
snap through the front of the panel. 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.

Auxiliary Switch: See Auxiliary Switch Ratings Table 2 for details.
Calibration: Breakers will hold 100% of rated current. Breakers may trip
between 101% and 124% of rated load (149% for 400 Hz.
units and 134% for AC/DC units). Breakers must trip at
125% of rated load and above (150% for 400 Hz. units and
135% for AC/DC units).
Dielectric Strength: 50/60 or 400 Hz., 1500V: DC, 1100V.
Insulation Resistance: 100 Megohms 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.
