GFCI/ELCI 

This catalog features Carling Technologies’ current line of GFCIs/ELCIs products, which offer 

maximum equipment protection against overload and short circuits. 

Carling’s Equipment leakage circuit breakers function as hydraulic/magnetic circuit breakers, 

offering customized overload and short circuit protection. In addition, they sense and guard 

against faults to ground using innovative electronics technologies. With the exception of small 

amounts of leakage, the current returning to the power supply will be equal to the current 

leaving the power supply. If the difference between the current leaving and returning through 

the earth leakage circuit breaker exceeds the leakage sensitivity setting, the breaker trips and 

its LED illuminates. The LED gives a clear indication that the trip occurred as a result of leakage 

to ground. This protection helps prevent serious equipment damage and fire. 

Typical Applications: 

• Marine 



2 | PB-Series - Introduction 

PB-Series 

Ground Fault Circuit Protection 

The PB-Series utilizes the hydraulic magnetic principle 

which provides precise operation and performance 

even when exposed to extremely hot and/or cold 

application environments. 

The new PB-Series, AC Residual Current Circuit Breaker 

with Overcurrent Protection (RCBO), combines the 

ground fault protection of a GFCI with the familiar 

overcurrent tripping characteristics of a normal circuit 

breaker. 

These precision mechanisms are temperature stable 

and are not adversely affected by temperature 

changes in their operating environment. As such, 

derating considerations due to temperature variations 

are not normally required, and heat-induced nuisance 

tripping is avoided. 

Features: 

• Overload, short circuit and ground fault protection 

in a single package 

• Handle or rocker style actuators 

• Wiping Contacts - Mechanical linkage with twostep 

actuation – cleans contacts, provides high, 

positive contact pressure & longer contact life. 

• A trip-free mechanism, a safety feature which 

makes it impossible to manually hold the contacts 

closed during overload or fault conditions. 

• A common trip linkage between all poles, another 

safety feature, ensures that an overload in one pole 

will trip all adjacent poles. 

• Front panel mounting 

• Integral push-to-test button 

Benefits: 

• Increases safety around boats and marinas 

• Protects against electrical shock hazards in 

areas near water 

• Protects against defects in wires & conductors 

• Reduces fire and shock hazards from defects in 

permanently installed appliances such as water 

heaters, battery chargers, lighting fixtures, etc. 

• Detects lower level ground faults which do not 

trip ordinary circuit breakers, but can lead to 

fires, and shock hazards for boating occupants

120 WHEN VAC VERSION ELCI/RCBO TRIPS: 

W/ REVERSE The PC-Series POLARITY ELCI/RCBO opens the circuit when there is an 

over INDICATOR current or ground fault condition. If the red LED is 

continuously illuminated the tripping is due to a ground fault 

condition. If the green LED is flashing, the tripping is due to an 

over current: 

1. Some faults are self-clearing. Try resetting the breaker 

once. 

2. If this device is installed as a main breaker, turn off all 

branch breakers and reset the breaker. If it does not trip, 

turn branch breakers on one at a time to locate the fault. 

3. If the breaker continues to trip with the branch breakers off 

recheck that the neutral is not grounded on the load side 

of the ELCI circuit breaker. 

4. If the breaker continues to trip, but no grounding of the

VERSION 

is observed, disconnect all load side connections 

W/ REVERSE and POLARITY reset the breaker. If the breaker still trips with no load 

INDICATOR connections in place, the breaker may be defective. 

5. If the breaker does not trip with the loads disconnected but 

does trip when the loads are connected, the device is 

performing its intended protection function, which means 

that a hazardous condition could exist. A qualified 

electrician should be called to evaluate the circuit and 

perform more advanced troubleshooting if the problem 

cannot be located.

16 | PD-Series - Introduction 

PD-Series 


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. 

Features: 



• Handle style actuators with optional 

“handleguard” 



positive contact pressure & longer contact life 





safety feature, ensures that an overload in one 

pole will trip all adjacent poles. 

• Front panel or DIN rail mounting options 

• “State of the art” integrated circuit developed by 

Carling 

• Equipment leakage sensitivity from 10 to 100 

milliamps 

• Integral push-to-test button and LED “tripped” 

indicator 

• Immediate reset after fault has been cleared

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 musthold 

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. 

4 TUV certifed units must have I-O or Dual legends
