Compact size and well known for its proven reliability, the A-Series
utilizes the hydraulic magnetic principle which provides precise
operation and performance even when exposed to extremely hot
and/or cold application environments. When aesthetics demand a
clean contemporary and functional design, the visi-rocker two-color
actuator can be specified. A rockerguard and push-to-reset bezel
help prevent inadvertent actuation. A specially constructed version
is now available for applications requiring CE markings. The
A-Series is used in many telecommunications and marine applica-
tions. In addition, these breakers meet CSA Standard 22.2 No.
100 for the Generator & Welder markets.

All A-Series Circuit Breakers will trip
on overload, even when the actuator
is forcibly held in the ON position.
The operating actuator moves posi-
tively to the OFF position when an
overload causes the circuit breaker
to trip. When mid-trip handle is spec-
ified, the handle moves to the mid
position on electrical trip of the cir-
cuit breaker. When mid-trip handle
with alarm switch is specified, the
handle moves to the mid position &
the alarm switch actuates when the
circuit breaker is electrically tripped.
