When it comes to electrical safety, not all RCCBs (Residual Current Circuit Breakers) are created equal. The TYPE-A RCCB steps up the game by detecting more types of electrical faults than the standard AC-type devices. If you’re using modern appliances, solar systems, or EV chargers, this is the protection your setup probably needs.
So, what makes TYPE-A RCCB different? While traditional RCCBs only catch sinusoidal AC faults, TYPE-A can also spot pulsating DC currents—the kind that leaks from things like washing machines, inverters, or medical equipment. Miss that, and you’ve got a hidden risk that could lead to fires or shocks.
Three big reasons. First, compatibility—today’s gadgets don’t just run on pure AC power. Second, safety—it catches tricky residual currents that older breakers ignore. Third, future-proofing—with more homes adding solar panels and electric vehicles, DC leakage is becoming a real concern.
Installation-wise, it works just like a regular RCCB but covers more ground. Electricians recommend them for kitchens, workshops, and anywhere you’ve got variable-speed drives or electronics. The cost is slightly higher, but compared to the risk of undetected faults, it’s a no-brainer.
Bottom line? If your place runs more than just lights and old-school appliances, TYPE-A RCCB is the smarter way to trip leaks before they trip you up. Check your switchboard—if it’s still all AC-type breakers, it might be time for an upgrade.
