Series 4001

Sub-Miniature Precision Circuit Breaker

The space-qualified product uti-

lizes the same internal design.

Single-Pole High

Performance

Qualified

To MS22073 of MIL-C-5809

Lightweight

Under 33 grams (.073 lbs)

High Interrupting Capacity

Interrupts up to 6,000A circuit at

30V, DC; and up to 3,500A cir-

cuit at 120V, 400 Hz. AC.

Not Sensitive To Frequency Or

Voltage

Breaker may be used on either

AC or DC circuits.

Performance Rated Circuit

Breaker

Meets or exceeds military speci-

fication requirements for durabil-

ity, vibration, mechanical shock,

and acceleration.Precision inter-

nal design provides a time-tem-

perature characteristic capable

of protecting either wire or

equipment. With a case 1 1/2

inches long, the breaker weighs

less than 33 grams, and is ideal

for today’s demanding design

requirements.
