Introduction:
JCR1-40 RCBO provides protection against earth faults, overloads, short circuits and domestic installation. The RCBO with both disconnected neutral and phase guarantees its proper actuation against earth leakage faults even when the neutral and phase are wrongly connected.
JCR1-40 electronic RCBO incorporates a filtering device preventing the risks of unwanted due to transient voltages and transient currents;
JCR1-40 RCBO's combine the overcurrent functions of an MCB with the earth fault functions of an RCD in a single unit.
JCR1-40 RCBO, which does the job of both an RCD and MCB, thus prevents this type of nuisance tripping and should be used on mission critical circuits.
JCR1-40 miniature RCBO's provide more wiring space in the enclosure for the installer making the whole installation process easier and quicker. During installation, resistance testing live and neutral conductors do not have to be disconnected. Now with an increased level of safety these JCR1-40 RCBO’s include switched neutral as standard. A faulty or damaged circuit is fully isolated by disconnecting the live and neutral conductors. Healthy circuits remain in service, only the faulty circuit is switched off. This avoids danger and prevents inconvenience in the event of a fault.
Type AC RCBOs are used for general purpose on AC (Alternating Current) only circuits. Type A are used for DC (Direct Current) protection, these mini RCBOs provide both levels of protection.
The A Type JCR1-40 RCBO responds to both AC and pulsating DC residual currents. It protects against both overcurrents due to overload and fault and residual current earth leakage. In either event, the RCBO interrupts the electrical supply to the circuit thus preventing damage to the installation and devices and electric shock to humans.
B curve JCR1-40 RCBO trips between 3-5 times full load current is suited for domestic application. C curve JCR1-40 rcbo trips between 5-10 times full load current is suited for commercial applications where there is greater chance of higher short circuit currents, such as inductive loads or fluorescent lighting.
JCR1-40 Available in current ratings that range from 6A to 40A and in B and C type tripping curves.
JCR1-40 RCBO Complies with BS EN 61009-1, IEC 61009-1, EN 61009-1, AS/NZS 61009.1

Why use Miniature RCBOs?
RCBO (Residual Current Circuit Breakers with Overcurrent Protection) devices are a combination of an RCD (Residual Current Device) and MCB (Miniature Circuit Breaker) in one.
An RCD detects Earth Leakage, i.e. current flowing where it shouldn’t, switching the circuit off where there is an Earth fault current. The RCD element of the RCBO is there to protect people.
In housing installations it’s not unusual to find that one or more RCDs are used alongside MCBs in the consumer unit, all grouped together protecting multiple circuits. What commonly happens when there is an earth fault on one circuit is that a whole group of circuits, including healthy circuits, are switched off.
In these instances, using RCDs and MCBs in groups goes against specific aspects of the IET’s 17th Edition Wiring Regulations. Specifically, Chapter 31-Division of Installation, regulation 314.1, which requires every installation to be divided into circuits as necessary –
1)To avoid danger in the event of a fault
2)To facilitate safe inspection, testing and maintenance
3)To take account of hazards that might arise from the failure of a single circuit e.g. lighting circuit
4)To reduce the possibility of unwanted tripping of RCDs (not due to fault)
