RCBO 63A 30ma DZ47LE-63

The RCBO 63A 30ma DZ47LE – 63 series residual current circuit breakers (RCCBs) are suitable for circuits with an alternating current of 50Hz, a rated operating voltage of 230V for single – pole two – wire and two – pole configurations, and 400V for three – pole, three – pole four – wire, and four – pole configurations, with a rated current up to 63A. They are used to provide indirect contact protection for personnel and overcurrent protection for building lines and similar applications. They can also protect against fires caused by persistent earth faults when overcurrent protection devices fail to operate. RCCBs with overvoltage protection can additionally protect against excessive voltage caused by power grid faults.

This series of products is increasingly being used as a backup protection for earth faults, direct contact, and indirect contact electric shock in low – voltage power distribution systems.

The products comply with the standards of GB 16917 – 1 and IEC 61009 – 1

RCBO 63A, 30mA DZ47LE-63 refers to that the DZ47LE-63 series products include Residual Current Operated Circuit Breaker with Overcurrent Protection (RCBO) with specifications of 63A and 30mA. Among them, “A” (Ampere) is the unit of current, and “63A” here denotes the rated operating current of the RCBO, meaning the component can continuously carry a maximum current of 63 Amperes under normal working conditions. “mA” (Milliampere) is another unit of current, with 1 Ampere equal to 1000 Milliamperes. “30mA” here represents the residual operating current of the RCBO—when the leakage current in the circuit reaches this value, the component will trip quickly to cut off the circuit. The smaller the value, the higher the sensitivity of the leakage protection. The 30mA specification is often used in places with high requirements for electric shock protection (such as household socket circuits).
