Introduction:
With ever growing number of residential installations which may have DC fault currents, our type A JCR2-63 RCBO can detect DC fault currents and make your electricity safer. Ideal for EV installation. It is ideal for PME fault protection or PEN LOSS consumer unit.
JCR2-63 RCBOs is a high-quality residual current circuit breaker and miniature circuit breaker combination with line voltage-dependent tripping and a wide variety of rated tripping currents. The built-in electronics precisely monitors where the currents flow. The difference between harmless and critical residual currents will be detected
JCR2-63 RCBO is an important safety measure when it comes to protection of electrical circuits. It is a current sensing device, which can automatically measure and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity. Having technology in place to automatically disconnect circuits in the event of an overload will ensure the prevention of damage to your networks, and the equipment that uses them.
JCR2-63 RCBO is available in Type A and Type AC. Type A Ensures tripping for residual a.c. currents and pulsating d.c. currents. A ttype JCR2-61 RCBO is a kind of safety protection device widely used in EV charger.
The rate current of JCB2LE-80M ROBO is upto 63A, available in 6A, 10A, 16A, 20A, 32A, 40A, 50A, 63A. Tripping sensitivity is available in 30mA, 100mA. Available in B or C tripping curves.
Type AC JCR2-63 RCBO is General purpose use, RCD can detect and respond to AC sinusoidal wave. Communally used in all residential installations as standard.
Type A JCR2-63 RCBO Can be used for general purpose and for equipment incorporating electronic components. The RCD can detect and react as Type AC as well as accommodate pulsating DC components.
JCR2-63 RCBO is combination of an RCD and MCB providing both earth leakage and overcurrent protection in one device. B curve are designed to trip between 3 to 5 times the full load current. C curve are designed to trip between 5 to 10 times the full load current. B curve are generally suitable for domestic applications. They may also be used in light commercial applications where switching surges are low or non-existent. C curve devices are the normal choice for commercial and industrial applications where some degree of electrical inrush is expected.

JCR2-63 Dimensions
Are RCDs required to supply a car charger?
Yes, regulation 722.531.3 requires that an RCD (Max 30mA) supplies a car charger and the RCD shall disconnect all live conductors. This includes the Neutral therefore the single-pole RCBOs should not be used for this application.
Some car charger manufacturers quote an RDC-DD, what is this?
An RDC-DD is a ‘Residual Direct Current – Disconnecting Device’. This is often built within the car charger equipment to monitor and if necessary disconnect should any DC problems appear on the AC side of the installation, which could affect the operation of RCDs
If a car charger does not have any RDC-DD then what type of RCD is required?
If the car charger does not have any RDC-DD then you will need a Type B RCD supplying the car charger. This is because Type B can detect this DC, still work and disconnect if required.
If a car charger does not have any RDC-DD then what type of RCD is required?
If the car charger does not have any RDC-DD then you will need a Type B RCD supplying the car charger. This is because Type B can detect this DC, still work and disconnect if required.
What type of RCD should be used if the car charger has an RCD-DD that will detect and disconnect any DC issues above 6mA?
In this case, a Type A RCD can be used. This is because Type A can still work correctly up to a level of 6mA DC. Over 6mA however, this Type-A device could be affected and possibly blinded and potentially stop working. This is the preferred option as Type A are now very common and lowest price. Therefore most car charger manufacturers have a 6mA RDC-DD built-in.
RCD in a series:
In some scenarios, someone may supply a car charger from an existing installation where they may consider installing from a spare way in the consumer unit. If there is no space for the new Type A RCD, they may consider installing this closer to the car charger.
The type A RCD will not be affected by DC up to 6mA. However, it’s important to consider the time frame of when the RCD was installed in the consumer unit. If it was installed some time ago, it could be a Type AC. This RCD may be also supplying other circuits within the house which could then be affected or in some cases blinded by any this DC that may be coming from the car. These other circuits then may not have any residual current protection, the consequences of which could be severe.
