JVL19-63 Residual Current Circuit Breaker RCCB is a Residual Current Circuit Breaker designed to protect against electrical shock and ground faults. It is available in two configurations: 1P+N and 3P+N.
The RCCB is available in both A and AC types, which refers to the sensitivity of the RCCB. An "A" type RCCB is sensitive to alternating current (AC) fault currents, while an "AC" type RCCB is sensitive to both AC and pulsating direct current (DC) fault currents.
This RCCB has a breaking capacity of 4.5kA, which means it can withstand short-circuit currents up to 4.5kA. It is suitable for use in applications where there is a risk of high short-circuit currents.
JVL19-63 Residual Current Circuit Breaker RCCB has a compact and ergonomic design. It is easy to install and operate, with clear markings on the device indicating its function and status. The RCCB has a high degree of resistance to external interference and voltage fluctuations, ensuring its reliable performance.
When the protected circuit is overloaded, the RCCB's handle will trip and remain in the center position, allowing for quick fault clearance. When manually operated, the handle cannot be held in this position.
This RCCB provides protection against ground faults and leakage currents, as well as isolation functions. It is equipped with finger-safe connection terminals for safety.
Overall, the JVL19-63 Residual Current Circuit Breaker RCCB is a reliable and cost-effective solution for protecting against electrical hazards in a variety of applications.

Residual Current Circuit Breaker RCCB Construction and Feature
● Residual Current Circuit Breaker RCCB provides ground fault/leakage current protection and isolation.
● Residual Current Circuit Breaker RCCB has high short-circuit current withstand capability.
● Suitable for terminal and pin/fork busbar connections.
● RCCB is equipped with a contact position indication function to facilitate users to check its status.
● It is also equipped with finger-proof connection terminals for added safety.
● Residual Current Circuit Breaker RCCB uses flame-retardant plastic parts and can withstand abnormal heating and strong impact.
● When a ground fault/leakage current occurs and the rated sensitivity is exceeded, the RCCB will automatically open the circuit.
● RCCB works independently of power supply and line voltage, and is not affected by external interference and voltage fluctuations.
