Dielectric Strength
UL, CSA 1500V, 50/60 Hz for one
minute between all electrically
isolated terminals. M-Series
Circuit Breakers comply with the
8mm spacing and 3750 V 50/60Hz
dielectric requirements from
hazardous voltage to operator
accessible surfaces, per

Standard Colors
10,000 ON-OFF operations @ 6
per minute with rated Current and
Voltage.
All M-Series Circuit Breakers will
trip on overload, even when
actuator is forcibly held in the ON
position.
The actuator moves positively
to the OFF position when an
overload causes the circuit
breaker to trip.

Series with or without
Auxiliary Switch.
Switch Only with or without
Auxiliary Switch.
Approximately 30 grams/pole
(Approximately 1.07 ounces/pole)

Environmental
Designed in accordance with requirements of specification
MIL PRF-55629 & MIL-STD-202G as follows:
Shock
Withstands 100 Gs, 6ms, sawtooth
while carrying rated current per
Method 213, Cond. I. Instantaneous
curves tested at 80% of rated
current.
Vibration
Withstands 0.060” excursion
from 10-55 Hz, and 10 Gs 55-500
Hz, at rated 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).
Thermal Shock
Method 107D, Condition A (Five
cycles @ -55°C to +25°C to +85°C
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 (hydrocarbon
based) solvents are not
recommended because they
attack plastics. Caution should
be taken when solvents are used
to clean and remove flux from
terminals. Lubricants should not
be introduced into the handle/
bushing openings
