RCBO circuit breaker, standing for Residual Current Breakers with Overcurrent, safeguards circuits against damage. This damage can result from short circuits, overloads, or leakage currents. If there’s an imbalance, an RCBO will trip.

Depending on specific needs and applications, you can choose from 1P+N or 3P+N RCBOs. Different amperages, like 6A, 10A,16A, 20A,25A, 32A, 40A, 63A, or 100ma, are available for various circuit capacities.

Discussing the operation of RCBOs, they protect against two types of electrical issues. First, they guard against residual currents or earth leakages. Such faults can occur due to accidental breaks in the circuit, resulting from wiring errors or mishaps such as cutting a cable during gardening.

Secondly, RCBO circuit breaker protect against overcurrent, which can appear as an overload or a short circuit. When too many devices overload a circuit, the power transfer surpasses the cable’s capacity. Conversely, short circuits happen when circuit resistance is too low, and amperage amplifies. This situation poses a higher risk than overload.
