JCR1-40 RCBO compact single module with switched live and neutral

The JCR1-40 RCBO combines residual current and overload protection functions in a modular design for industrial, commercial and residential electrical systems, with switchable live and neutral poles, 6kA breaking capacity, and complies with IEC 61009-1 standards, ensuring reliable circuit isolation and simplified installation.

JCR1-40 Rcbo can meet modern electrical safety needs in different environments. The compact single-module structure is designed for integration into consumer units and distribution boards, which can optimize space efficiency and provide dual functions of residual current detection and overcurrent protection. Monitoring live and neutral conductors, it can detect imbalance caused by leakage and automatically disconnect the circuit to prevent dangers such as electric shock or fire. The 6kA breaking capacity can be upgraded to 10kA, ensuring strong performance under high fault conditions, protecting equipment and infrastructure from damage.

The JCR1-40 Rcbo has been carefully designed to provide adjustable trip curves (B or C) and sensitivity settings (30mA, 100mA, 300mA) to be customized to specific load requirements. The inclusion of Type A and Type AC variants enhances compatibility with different current waveforms, including pulsating DC components common in modern electronics. The switch neutral pole eliminates the need for an external neutral link during installation, reducing wiring complexity, speeding up commissioning testing, and saving time and labor costs. The double-pole switching mechanism ensures complete isolation of the faulted circuit, improving maintenance safety by disconnecting both the live and neutral wires simultaneously.

The JCR1-40 Rcbo complies with IEC 61009-1 and EN61009-1 standards and has been rigorously tested to ensure reliability under extreme conditions. Supporting rated currents up to 40A, with options ranging from 6A to 40A, it meets the needs of low-power lighting circuits and high-demand motor systems. Electronic operation ensures consistent performance regardless of voltage fluctuations, allowing effective use in environments such as construction sites with unstable power quality or aging power grids.

The compact form factor design seamlessly retrofits into existing panels without taking up space from other components. Intuitive terminal design and clear fault indicators simplify troubleshooting. Advanced protection features are integrated into a user-friendly package to minimize downtime and maintenance efforts.

The JCR1-40 Rcbo combines high breaking capacity, configurable sensitivity and double-pole switching to address safety and efficiency challenges in modern electrical systems.
