Main Features and Functions

Residual current protection: When the residual current (i.e., leakage current) in the circuit reaches a preset value, the RCBO is able to act quickly to cut off the circuit, thus preventing electrocution accidents and electrical fires.

Overload protection: When the current in the circuit exceeds the rated current of the RCBO, it is able to cut off the circuit within a specified period of time, thus preventing damage to the circuit or fire accidents caused by overload.

Short-circuit protection: When a short-circuit occurs in the circuit, RCBO can act quickly to cut off the short-circuit current and protect the safety of the circuit and equipment.

B-type release characteristics: As mentioned above, B-type RCBOs are particularly suitable for loads that are not sensitive to instantaneous overloads, but sensitive to prolonged overloads.

Application Scenarios

6ka 3p+N Leakage Circuit Breaker a (AC) Type RCBO with Cable are widely used in places where a variety of circuit protection functions are required, especially those circuits that use loads with special requirements for overload characteristics. Example:

Residential and commercial buildings: used to protect lighting circuits, socket circuits, etc. to ensure personal safety and equipment safety.

Industrial places: for protecting various industrial equipment, such as resistance heaters, incandescent lamps, etc., to prevent equipment damage or fire accidents caused by overload or leakage.

Agriculture and horticulture: used to protect agricultural equipment such as greenhouses, irrigation systems, etc., to ensure the normal operation of the equipment and the safety of personnel.

Precautions and Maintenance

Correct selection of rated current: When selecting the 6ka 3p+N Leakage Circuit Breaker a (AC) Type RCBO with Cable , the appropriate rated current value should be selected based on the rated current and characteristics of the load.

Periodic Inspection and Maintenance: Periodically inspect and maintain the RCBO to ensure that it operates reliably, is securely wired, and is free from damage or corrosion.

Avoid false operation: When installing and using, care should be taken to avoid installing the RCBO in an environment susceptible to interference in order to prevent its false operation.

Timely handling of faults: When RCBO fails or operates, the cause should be identified and troubleshooting should be done in time to ensure the safe operation of the circuit.
