🔷 Product Type
Residual Current Circuit Breaker (RCCB) – TYPE A
🔷 Short Description (Marketplace Summary)
This TYPE A 4 Pole RCCB provides advanced earth leakage protection by detecting AC as well as pulsating DC leakage currents. Designed for modern 3-phase installations using electronic equipment, it ensures enhanced human safety, fire protection, and reliable tripping where standard TYPE AC RCCBs may fail.
🔷 Key Features (High-Conversion Bullet Points)
TYPE A Advanced Leakage Protection
Detects AC + pulsating DC earth leakage currents, ideal for modern electronic loads.
4 Pole Full Isolation (L1 + L2 + L3 + N)
Simultaneously disconnects all three phases and neutral for complete system safety.
Reliable Life Protection (30mA Sensitivity)
Trips instantly to protect against fatal electric shock and insulation failure.
Essential for Electronic & Non-Linear Loads
Suitable for VFDs, UPS, inverters, SMPS, elevators, and EV-related equipment.
Electromechanical Tripping
Independent of supply voltage; works reliably even during neutral instability.
DIN Rail Mount – Panel Ready
Standard 35mm DIN rail design for easy installation in distribution boards.

🔷 What TYPE A Means (Customer-Friendly Explanation)
TYPE A RCCB detects:
✔ AC leakage current
✔ Pulsating DC leakage current
⚠️ Standard TYPE AC RCCB cannot detect DC leakage, which may occur in modern electronic devices and can block proper tripping.
➡️ TYPE A is safer and recommended for today’s electrical systems.
🔷 Recommended Applications (Very Important for TYPE A)
✔ Elevators & lifts
✔ VFD / motor drive panels
✔ UPS & inverter systems
✔ Solar inverters
✔ EV chargers
✔ Commercial & industrial buildings
✔ Modern residential main incomers
🔷 Protection Coverage
✅ Electric shock protection
✅ Fire due to earth leakage
✅ AC + pulsating DC leakage
✅ Neutral leakage faults
✅ Full 3-phase isolation
🔷 What This RCCB Does NOT Protect
❌ Overload
❌ Short circuit
➡️ Always use with MCB or MCCB
