Commercial: 100mA RCCB for distribution boards (3P+N config)
Industrial: 300mA RCCB with 10kA breaking capacity
While RCCBs protect against earth leakage currents, RCBOs combine leakage protection with overcurrent/short-circuit protection in one device.
Residential: 30mA | Commercial: 100-300mA | Industrial: 300mA-1A. View selection guide
✅ Operating Principle:
RCCBs use a core balance magnetic ring to monitor current flow in live (L) and neutral (N) wires. Under normal conditions, L and N currents are equal. If leakage occurs (e.g., human contact), current imbalance activates the tripping mechanism. When difference exceeds sensitivity (e.g., 30mA), it cuts power in 0.1 seconds.
Key Component: Summation Current Transformer
⚡ Core Definition:
An RCCB is a life-saving electrical device that detects earth leakage currents caused by:
• Insulation faults • Human electric shock risks
It does NOT provide overcurrent protection (requires pairing with MCB). Main parts:
Zero-sequence CT (detects imbalance)
Trip solenoid
Test button (simulates 10mA-30mA leakage)
Step-by-Step Process:
Phase & neutral wires pass through magnetic core
During leakage, current imbalance creates magnetic flux
Induced current triggers trip mechanism
Contacts open within 30ms (faster than heartbeat)
✅ Test Feature: Pressing test button creates artificial leakage to verify function.
Evolution of Protection:
| Parameter | Voltage-ELCB (Obsolete) | Current-ELCB (RCCB) |
|---|---|---|
| Detection Method | Earth wire voltage | L/N current imbalance |
| Sensitivity | 500mA-1A | 30mA-300mA |
| Safety | Fails if earth wire broken | Works without earth wire |
| Modern Compliance | Not IEC 61009-1 | IEC 61009-1 Certified |
Critical Note:
Modern "ELCB" refers to RCCB in most regions. True voltage-based ELCBs are discontinued due to safety flaws.
