>Product Overview

CZB5LE-63 series residual current-acting circuit breakers are suitable for use in lines with AC 50Hz or 60Hz, rated voltage up to 400V and rated current up to 63A. When the personal electric shock or grid leakage current exceeds the specified value, the residual current action circuit breaker can automatically cut off the power within a very short period of time to protect personal safety and prevent accidents caused by leakage current of equipment.

Residual current-actuated circuit breakers also have overload and short-circuit protection, which can be used to protect the line from overload and short-circuit, and can also be used for infrequent switching of the line under normal conditions.

Suitable for use in a wide range of industrial, commercial, high-rise and residential premises.

Products comply with standards: 1EC61009-1, GB/T16917.1.
