Our RCBOs have been designed to combine earth leakage and overload protection in one compact unit. All have a sensitivity setting of 30mA, 100mA, 300mA and are availablein various current ratings. These protection devices are suitable for domestic, commercial and industrial applications.
Description
1. Application.
MSLE-63 series leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage. MSLE-63 series leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as well as infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
