FAQ
Q: Can this RCCB replace an ELCB?
A: Yes! Modern 2-pole RCCBs offer superior accuracy compared to traditional ELCBs by detecting both residual and pulsating DC currents.
Q: Is 30mA sensitivity safe for homes?
A: Absolutely. 30mA is the gold standard for personal shock protection, balancing safety and nuisance-tripping prevention.
Q: Does it work with solar systems?
A: Yes! The A-type sensitivity (optional) supports protection in systems with pulsating DC currents, like solar inverters.
