contact design insures long term reliability. Various styling options
allow design flexibility.
Typical applications include power supplies, medical equipment,
and telecommunications equipment. In addition, these breakers
meet CSA Standard 22.2 No. 100 for the Generator & Welder
markets.

Shock
Withstands 100 Gs, 6ms, sawtooth
while carrying rated current per
Method 213, Cond. I. Instantaneous

current per Method 204C, Test
Condition A. Instantaneous curves
tested at 80% of rated current.
Moisture Resistance
Method 106D, i.e., ten 24-hour
cycles @ + 25°C to +65°C, 80-98% RH.
Salt Spray
Method 101, Condition A (90-95%
RH @ 5% NaCl Solution, 96 hrs).

to +25°C).
Operating Temperature
-40° C to +85° C
Chemical Resistance
Only the outside surfaces of the case
and the handles may be cleaned with
detergents or alcohol. Organic (hydro-
carbon based) solvents are not rec-
ommended because they attack plas-
tics. Caution should be taken when
solvents are used to clean and
remove flux from terminals. Lubricants
should not be introduced into the han-
dle/bushing openings.
