Electronic Type RCBO

Electronic Type RCBO can connect and break the current in the main circuit, and automatically cut off the circuit when residual current (leakage current) occurs in the main circuit, in order to prevent personal electric shock or electrical fire accidents. At the same time, RCBO also has an overcurrent protection function, which can cut off the circuit when overload or short circuit occurs in the circuit to protect the safety of the circuit and equipment.

Selection and Installation

When selecting the type, it should be chosen according to the parameters such as rated voltage, rated current, short circuit breaking capacity and leakage action current of the circuit. At the same time, the number of poles of RCBO and the number of current loops should also be considered to meet the protection requirements of the circuit.

When installing, the following principles should be followed:

The RCBO should be installed in a dry, ventilated place with no corrosive gas and no danger of explosion.

The wiring of the RCBO should be correct and reliable, with no loose or poor contact.

The operating mechanism of RCBO should be flexible and reliable, easy to operate and maintain.

RCBO should be inspected and tested regularly to ensure its reliable performance.

Maintenance and Overhaul

During the use of the RCBO, maintenance and overhaul should be performed periodically to ensure proper operation. Maintenance and overhaul includes:

 Check whether the appearance and wiring of the RCBO are intact, with no damage or looseness.

 Check whether the operating mechanism of the RCBO is flexible and reliable, and whether there is any jamming or malfunctioning phenomenon.

 Check whether the residual current protection function and overcurrent protection function of the RCBO are normal.

 Clean and dust the RCBO to keep it dry and clean.

This kind of RCBO (MCB+RCCB) function as combination of circuit breaker and residual current device, which protect human from the fault of electric because of over-current, short circuit, earth fault current. It is self-protecting up to a maximum short-circuit current 32A or 40A . And comply with Standard IEC/EN 61009.1.
