Hydraulic-Magnetic Circuit Breaker
Compact and Versatile Design
The A-Series hydraulic-magnetic circuit breakers offer
precise operation in a compact size for both general
purpose as well as full amp load applications. Visi
Rocker® and recessed paddle actuators are ideally
suited for clean, front panel designs while the metal
toggle configuration is ideal for harsh environments. The
A-Series is available as a one to six pole configuration,
rated up to 50 amps, 277VAC/80VDC and has a max IC
of 7,500 amps.

UL, CSA - 1500V 60 Hz for one
minute between all electrically
isolated terminals. A-Series
rocker circuit breakers comply
with the 8mm spacing & 3750V
dielectric requirements from
hazardous voltage to operator
accessible surfaces per EN 60950
and VDE 0805.
Values from Line to Load Terminal
based on Series Trip Circuit
Breaker.
Mechanical
Endurance
10,000 ON-OFF operations @ 6
per minute; with rated Current &
Voltage.
All A-Series Circuit Breakers will
trip on overload, even when the
actuator is forcibly held in the ON
position.
The operating actuator moves
positively to the OFF position
when an overload causes the
circuit breaker to trip. When
mid-trip handle is specified, the
handle moves to the mid position
on electrical trip of the circuit
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
