TYPE-A RCCB: The Smarter Leakage Protection You Need

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.  

Why Should You Upgrade to TYPE-A RCCB?  

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.
