GE Power Controls, a global leader in Electrical Control &

Protection equipment offers Safe-trip RCCBs and RCBOs

for reliable Protection of human beings and Installations from:

Shock Hazards Electrical Fire

- RCCB : residual current operated circuit breakers without integral

overcurrent protection.

- RCBO : residual current operated breakers with integral

overcurrent protection.

GeneralElectricity if used without proper caution can be lethal. Leakage

currents, arising due to faulty Wiring or damaged insulation flow to

earth through an alternate path. Any direct or indirect contact with

the leakage current can be lead to fatal accidents. Consistent

leakage currents of about 300 - 500 mA heat up the current path

(material in-appropriate to actually carry current) and are capable of

causing sparks that ignites fire.

Direct Contact Indirect Contact

RCCB

Operational Principal

Safe-trip RCCBs and RCBOs are current operated devices and are

independent of line voltage conditions. This means that they provide

protection even when there is voltage dip or the neutral conductor is

interrupted.

In a healthy system the vector sum of all currents in phase and

neutral is equal to zero. The device senses imbalance or residual

currents in the system and disconnects unhealthy circuit.

The supply conductors that is phase and neutral are passed through

a torroidal current transformer. In an unhealthy circuit a residual

current flows in the system which is fed to a highly sensitive

electromagnetic relay connected to secondary winding. On receipt of

signal the electromagnetic relay mechanically actuates the tripping

mechanism thereby instantaneously isolating the defective circuit.

The tripping time is < 40 ms as per IEC 1008.

As per Indian Electricity Rules - 61a, 71(1), 73(1), usage ofRCCB, in all installation 5KW and above; in all luminoustubesigns & X-Ray installations, is mandatory.

Features

Compact Size:

The RCCBs and RCBOs are sized in 2 & 4 module configurations;saving space in Distribution board.

Disconnector Function:It incorporates neutral advance mechanism for safe interruption andcan be used as a isolator.

Anti Welding Contacts:The contact tips are made of silver Graphite which has highconductivity and anti welding properties. This ensures reliableoperation of the devices under fault conditions as contacts do notweld under fault conditions.

Terminal Design:

- Dual TerminalsDouble function terminal allow simultaneous termination of busbar& conductors.

- Touch Proof TerminalsThe terminals are touch proof to ensure maximum operator safety.

- Terminal SizeThe terminals can accommodate conductors up to 25mm2

facilitating ease of wiring.

Resistance against Unwanted Tripping:A special filter circuit is incorporated to avoid nuisance tripping dueto impulse voltage.

Positive Contact Indication:The Red and Green making on the operating knob indicates the ON& OFF position in 2P RCCB & RCBO. In 4 module the same isindicated through flag in the window provided above the operatingknob.

Testing Function:A test knob (T) is provided on the device to check the electrical &mechanical effectiveness. The RCCB/RCBO should be electricallyconnected in the circuit when the test knob is operated, the deviceshould trip instantaneously. It is recommended that the test knobshould be operated periodically (at least once a month).

No Ageing Effect:No deviation in the characteristics shall occur over long periods ofusage.

Effect of AC Current (50Hz) on human body as perIEC 60479-1

Zone 1 : Usually no reaction effect.

Zone 2 : Usually no pathophisiologically dangerous effect.

Zone 3 : Usually no danger of fibrillation.

Zone 4 : Fibrillation possible (C1-C2 - upto 5%, C2-C3 upto 50% andbeyond C3>50%)

Wiring Precautions• The neutral conductor on the load end should not be connected

to earth.

• In case of 3P 3 wire system appropriate care should be taken offor wiring as shown in the diagram.

• Earth loop impedance specified on the unit label not to exceedmaximum permissible touch voltage of 50/25V AC (Daily/Dampconditions).
