RCBO 4 Pole TYPE A 63A 30mA | 3 Phase + Neutral Residual Current Circuit Breaker with Overload & Short Circuit Protection | AC + DC Leakage | DIN Rail Mount (3 PHASE 63AMPS)

Features

• ALL-IN-ONE PROTECTION RCBO Combines RCCB + MCB in one device, providing earth leakage, overload, and short-circuit protection for complete electrical safety.
• TYPE A ADVANCED LEAKAGE DETECTION Detects AC and pulsating DC leakage currents, making it ideal for modern electronic loads where standard breakers may fail.
• IMPORTANT BEFORE BUYING TEST BUTTON WORKING CONDITION (VERY IMPORTANT) This is a 3-phase (3P+N) RCCB/RCBO device. The TEST button is designed to simulate leakage across phases. It will ONLY work when ALL 3 phases (R, Y, B) AND Neutral are connected and live (energized). If any one phase is missing or not powered: The TEST button may NOT trip This does NOT mean the product is faulty Important understanding: The TEST function depends on proper 3-phase supply to create an internal imbalance. Without full phase supply, the test circuit cannot operate. .
• LIFE & FIRE SAFETY (30mA SENSITIVITY) Trips instantly to protect against fatal electric shock and electrical fires caused by insulation failure.
• OVERLOAD & SHORT-CIRCUIT PROTECTION (TYPE C CURVE) Handles inrush current from motors, elevators, and industrial equipment while ensuring fast fault clearance.
• DIN RAIL MOUNT SPACE SAVING DESIGN Compact 35mm DIN rail mounting, reduces panel wiring, saves space, and improves reliability.
• 4 POLE COMPLETE ISOLATION (L1 + L2 + L3 + N) Safely disconnects all three phases and neutral simultaneously during fault conditions in 3-phase systems.
