Are Your Current RCCBs Providing Complete Protection for Modern Electrical Loads?
2025-08-12
In my two decades as an electrical safety consultant, I've investigated numerous shock incidents where conventional RCCBs failed to respond. GreenWatt® TYPE-A RCCB addresses these gaps with advanced detection capabilities. But how do you know if you need this enhanced protection?
What Makes TYPE-A RCCB Different from Standard Models?
| Detection Capability | GreenWatt® TYPE-A | Basic AC-Type |
|---|---|---|
| AC sinusoidal currents | Yes | Yes |
| Pulsating DC currents | Yes | Partial |
| Smooth DC currents | Yes | No |
| Mixed frequency currents | Yes | No |
| High-frequency currents | Up to 1kHz | Limited |
These technical differences translate to real-world safety - we've documented cases where only TYPE-A detected dangerous leakage currents.
Where Is GreenWatt® TYPE-A RCCB Protection Essential?
-
Solar PV systems
-
EV charging stations
-
Medical facilities

One hospital installation prevented a potential disaster when our TYPE-A RCCB detected DC leakage that standard devices missed.
How to Properly Select and Install TYPE-A RCCB?
-
Calculate total possible leakage current
-
Verify system voltage compatibility
-
Select appropriate sensitivity (10mA/30mA/100mA)
-
Ensure proper load balancing
-
Test monthly using manufacturer's procedure
