Series 160 Compact Protection For Higher Current Ratings
Single-Pole High
Performance
Qualified
To MIL-C-5809 and MS25361.
Protection For Heavy-Duty
Systems
Protects circuits from 50 to 100
amperes.
Heavy-Duty Construction
Breaker features large contacts
and wide terminals.
Not Sensitive To Frequency
May be used on either AC or DC
circuits.
Performance Rated Circuit
Breaker
The 160 series has the recogni-
tion of being the most specified
heavy-duty aircraft type circuit
breaker in the 50 to 100 ampere
rating range.
Designed to protect heavy-duty
aircraft and non-aircraft electrical
systems, this trip-free breaker
features separate, durable, over-
load and mechanical latches. In
addition, the overload latch is
designed for precise operation.
Extra heavy contacts are spring-
loaded to maintain high-contact
pressure and assure long life.
Contact material has high resist-
ance to arcing and the corrosive
action of moisture —thus assur-
ing low voltage drop throughout
the life of the breaker.
