Current Ratings
Mechanical
277VAC 50/60 Hz, 80VDC
Standard current coils: 0.100,
0.250, 0.500, 0.750, 1.00, 2.50,
5.00, 7.50, 10.0, 15.0, 20.0, 25.0,
30.0, 35.0, 40.0, 50.0. Other ratings
available - consult ordering
scheme.
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

Trip Indication
Standard Voltage Coils DC-6V, 12V; AC-120V, Other ratings
available, consult ordering scheme.
Auxiliary Switch Rating SPDT; 10.1 A - 250VAC,
1.0 A-65VDC/0.5 A - 80 VDC,
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.

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.
