PD-Series
Ground Fault Circuit Protection
SmartGuard is an equipment ground fault protection
device that functions as a standard high-quality
Carling hydraulic/magnetic circuit breaker, offering
customized overload and short circuit protection.
In addition, this breaker senses and guards against
faults to ground using a state of the art integrated
circuit developed by Carling. This new technology
detects faults and when a fault occurs, the breaker
trips and an LED illuminates. The LED gives a clear
indication that the trip occurred as a result of leakage.
This protection helps prevent serious equipment
damage and fire.

All SmartGuard equipment leakage
circuit breakers will trip on overload

actuator is forcibly held in the ON
position.
The actuator moves to the OFF
position when an overload or earth
leakage ground fault causes the
breaker to trip. The LED is illuminated
when leakage to ground causes the
circuit breaker to trip.

Delay Curves 21,22,24,26: Breakers to hold 100% and must trip at 125%
of rated current and greater within the time limit shown in this curve.
Delay Curve 20: Breakers to hold 100% and must trip at 150% of rated
current and greater within the time limit shown in this curve.
All Curves: Curve data shown represents breaker response at ambient
temperature of 77°F (25°C) with no preloading. Breakers are mounted in
standard wall-mount position.
The minimum inrush pulse tolerance handling capability is 12 times the
rated current. These values are based on a 60 Hz 1/2 cycle, 8.33 ms pulse.

Notes:
1
Units with a switched or unswitched neutral connection are the same size as a unit with
an additional breaker pole (e.g. a 2-pole unit with a switched or unswitched neutral is the
same physical size as a 3-pole unit.)
Switched neutral poles contain the same overcurrent protection as the other poles.
2
The leakage currents shown will cause the breaker to trip (must-trip current). The must-
hold current is 67% of the must-trip current.
3
All breakers are front panel mountable using screw size shown. Breakers may also be
mounted on either 35mm x 7.5mm or 35mm x 15mm symmetrical DIN rail.
