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 small RCBO?

Miniature RCBOs (Residual Current Circuit Breakers with Overcurrent Protection) offer a compelling solution for electrical installations due to the unique combination of RCD (Residual Current Device) and MCB (Miniature Circuit Breaker) functions in a single device. RCBO's RCD components are specifically designed to detect earth leakage, preventing the risk of current flowing where it shouldn't and providing vital protection to individuals.

In traditional residential installations, a combination of RCDs and MCBs are often used in consumer units to protect multiple circuits. However, this approach can lead to a situation where a ground fault on one circuit triggers the disconnection of an entire group of circuits, including those that are functioning normally. This practice violates the specific provisions outlined in the IET Wiring Regulations, 17th Edition, in particular Chapter 31 - Installation, Clause 314.1.

Regulation 314.1 emphasizes the need to divide installations into circuits to achieve several key objectives, including avoiding hazards in the event of failure, facilitating safety inspection, testing and maintenance, taking into account hazards arising from faults in individual circuits, and reducing inaccuracies not caused by faults. Possibility of necessary RCD tripping.

By integrating micro RCBOs into electrical installations, these devices are able to comply with the regulatory requirements outlined in the IET 17th Edition Wiring Regulations. They provide a more precise and targeted approach to circuit protection, ensuring that disconnection of a circuit is limited to the specific area affected by a fault, thereby increasing safety, minimizing disruption and simplifying maintenance and testing procedures. This makes micro RCBOs the first choice for modern electrical installations, complying with the principles of safety, efficiency and regulatory compliance.
