125/250 VAC 50/60 Hz, 80 VDC

(See Rating Tables.)

Standard current coils: 0.100, 0.250,

0.500, 0.750, 1.00 thru 15.0 in 1

amp increments, 18.0,

20.0, 25.0, 30.0. Other ratings avail-

SPDT; 7A 250VAC, 7A (Res)

28VDC, 4A (Ind.) 28VDC, 0.25A

80VDC (Res) (silver contacts), 0.1A

125VAC (gold contacts).

Minimum of 100 Megohms at 500

VDC.

UL, CSA 1500V, 50/60 Hz for one

minute between all electrically isolat-

ed terminals. M-Series Circuit

Breakers comply with the 8mm

spacing and 3750 V 50/60Hz dielec-

tric requirements from hazardous

voltage to operator accessible sur-

faces, per Publications IEC 380,

435, 950, EN 60950 and VDE 0805.

Values from Line to Load Terminal -

based on Series Trip Circuit Breaker.

Endurance

Trip Free

Trip Indication

Physical

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.

Number of Poles

1 or 2

Internal Circuit Configurations Series with or without Auxiliary

Switch.

Switch Only with or without Auxiliary

Switch.

Weight

Approximately 30 grams/pole

(Approximately 1.07 ounces/pole)

Standard Colors

See Ordering Scheme.

Environmental

Designed and tested in accordance with requirements of specifi-

cation MIL-PRF-55629 & MIL-STD-202 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 (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.
