Current Metering
I~
(FROM 1 - 30 AMPS)
Integrated current transformer.
Measurement range: 1-30 Amps.
Voltage output: 10mV per Amp
according to the formula below:
2(Amp) ≤ I ≤ 30(Amp)
V = 0.01× I ± 2%
(with current metering codes 1 or 2)
V = 0.01× I ±1%
(with current metering codes 3 or 4)

Where V=CT output in volts
V₁₀=CT output in volts with
I=I₁₀=10 (A); I=primary current in
amperage (50/60 Hz). Phase shift
between primary current and CT
output is 0.25±0.25°. Maximum
crest factor of primary current is 1.73.
R1 shall be integrated in the breaker.
R2 and R3 are provided by end user
and external to the breaker.
Connection: below Load Terminal.
2-pin connector, Molex 35362-0250.

Interrupt Capacity
UL, CSA-1960V 50/60 Hz for one
minute between all electrically
isolated terminals. Comply
with the 8mm spacing and 3750V
50/60 Hz dielectric requirements
from hazardous voltage to operator
accessible surfaces and between
main circuits of adjacent poles per
Publications EN 60950 and VDE 0805
See next page
Minimum of 100 Megohms @ 500VDC
50 operations @ 600% of rated current
for AC rated devices

Mechanical
Endurance
Trip Free
Trip Indication
10,000 “On-Off” operations @ 6 per
minute; with rated current & voltage
Trips on overload even when
actuator is forcibly held in the “On”
position
The operating actuator moves
positively to the “Off” position
when an overload causes the
breaker to trip
