CIRCUIT BREAKER
A-Series
Well known for their proven reliability, Carling Technologies’ A-Series hydraulic magnetic circuit breakers are
compact, temperature stable and designed for precision operation in OEM markets requiring general purpose
as well as full load amp applications. When front panel operation and aesthetics demand a clean, contemporary
design, the visi-rocker or paddle actuators are ideally suitable. A sealed toggle actuator style is also available and
ideal for harsh environment applications requiring additional sealing protection. Optional rocker-guard and push-
to-reset bezels, which help prevent inadvertent actuation, are also available.

Auxiliary Switch Rating SPDT; 10.1 A - 250VAC,
1.0 A-65VDC/0.5 A - 80 VDC,
0.1A - 125VAC (with gold contacts).
Insulation Resistance
Minimum: 100 Megohms at 500
VDC
Dielectric Strength
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.

Trip Indication
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.

switch), Shunt and Relay with current
or voltage trip coils, Dual Coil,
Switch Only with or without auxiliary
switch.
