Residual Current Breaker with Over-Current
RCBO is a Residual Current Circuit Breaker with over-current protection. As indicated by its name, it offers protection for two types of faults namely, residual current or earth leakage faults, and over-current faults inclusive of overload and short circuit protection. Hence it is a combination of MCB and RCCB. Such devices allow for disconnection of the circuit for the protection of people and equipment if the current becomes unbalanced. The general recommendation is that an electrical RCBO be attached to each separate circuit, meaning that a fault in one circuit will not affect the functioning of the others, thus preventing nuisance tripping. RCBO breaker can be operated exclusively of other overcurrent protective devices within the rated short-circuit capacity.
IPD offers ABB’s RCBO, a compact solution for complete protection. Its features include easy installation due to the composition of two different seats for cables and busbars, mounting clip for stable and fast mounting, easy troubleshooting and reduced downtime for maintenance operations. This is due to both the blue indicator, that signals the differential tripping to immediately identify any earth fault by displaying the operational status.
Other features of the ABB RCBO range include reliability in extreme conditions, improved combination with System pro M compact® accessories, laser printed information to ensure readability over time and presence of an RFID tag in order to authenticate the product.
