Description
Anchor Uno RCCB 63A DP 100mA
Anchor Uno RCCB 63A DP 100mA – Residual Current Circuit Breaker (RCCB) also called Earth Leakage Circuit Breaker (ELCB) is a device designed to disconnect the load from the supply mains, when the residual current (I∆n) is flowing in the circuit. The flow of currents in the electrical system is risky. Low quality faulty wires, poorly insulated equipments or incorrect use of electrical devices cause current to flow through the wrong path to the earth. This current is called “Leakage Current”.

Why Anchor Uno RCCB 63A DP 100mA (98211) when MCB is already provided?
There are two types of electrical issues that are extremely dangerous.
- High current faults are caused by short circuit current or low resistance faults and are protected by the MCB.
- Earth Leakage due to poor insulation of the device/cable/socket or accidental human contact. The MCB cannot detect such low leakage currents and takes no action, resulting in equipment damage or fatal consequences for person. Here RCCB plays an important role in electrical protection.
Protection Against Direct Contact
Accidental contact with live parts of electric appliances cause earth leakage current to flow through the human body resulting in shocks that may be fatal. Anchor Uno RCCB 63A DP 100mA trips immediately under these circumstances and saves human lives. For e.g. when someone makes contact with a live electrical component of a device, touches a live bus bar in distribution panel or unprotected test cables or when a person sticks a metal object into a power socket or touches a live cable.
Protection Against Indirect Contact
The metal enclosures of electric appliances can become live and cause electric shock to unwary persons touching them during an internal fault or insulation ailure. Anchor Uno RCCB 63A DP 100mA trips instantaneously and thus removes the possible risk from dangerous indirect contact. Indirect contacts are independent of humans, such as a person touching an electric metal frame. This is when a person makes contact with a metal earthed part which has accidently been powered up following an insulation fault. These type of contacts are very dangerous.

Will Anchor Uno RCCB 63A DP 100mA (98211) function if earth wire is disconnected
If for some reason the earth wire is disconnected and the live wire insulation in the device is weakened, leakage current should flow through the earth wire, else the electric current will try to create a instant impact on the body of the person who touches the device. However, the Anchor Uno RCCB 63A DP 100mA (98211) trips quickly and the harm to the human body is only a function of RCCB’s sensitivity and trip time.
