DZ47LE-63 MCB Miniature Circuit Breaker

The 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
