RCBO Price in Sri Lanka – Residual Current Breaker with Overcurrent from India
RCBOs (Residual Current Breakers with Overcurrent protection) in Sri Lanka for combined earth fault and overcurrent protection in a single DIN rail module. RCBOs are increasingly specified in Sri Lankan residential wiring, hotel projects, and commercial fit-outs replacing separate RCCB + MCB combinations. myelectric.in supplies RCBOs from Schneider Electric, ABB, and L&T at zero import duty.
RCBO Range for Sri Lanka
| Rating | Sensitivity | Poles | Type | Application |
|---|---|---|---|---|
| 6A–16A | 30mA | 1P+N | Type A | Residential outlets, washing machine, dishwasher |
| 20A–32A | 30mA | 1P+N | Type A | Air conditioners, water heaters |
| 40A–63A | 100mA | 2P, 4P | Type AC | Sub-distribution boards, feeder protection |
| 63A–125A | 300mA | 4P | Type S (selective) | Main incomer — coordinates with downstream 30mA |
RCBO vs RCCB + MCB in Sri Lanka
A single Schneider Acti9 RCBO (iC60N + Vigi block) saves 1 DIN module width per circuit vs a separate RCCB and MCB, reducing panel size and wiring complexity. Sri Lanka’s CIDA and hotel projects increasingly specify Type A RCBOs for circuits supplying washing machines and VFDs that can produce DC leakage currents not detected by Type AC devices.
