Core Features
Precision Leakage Protection
Utilizes electromagnetic tripping technology with a sensitive 30mA leakage detection threshold, critical for human body protection, effectively isolating circuits within 100ms upon fault detection.
Dual-Function for overcurrent/short-circuit events (6A-63A range) with leakage protection, replacing traditional CBs + RCDs setups and reducing panel space.
Robust Construction
- Arc Chute System: Self-extinguishing arc chambers accelerate arc quenching at high fault currents.
- Visual Status Indicators: Clear contact position labeling (I/O).
- Test Button: Integrated monthly functional verification mechanism.
Adaptive Applications
Suitable for residential branch circuits (power outlets, lighting) and commercial environments requiring 2P isolation:
- Low Rating (6-25A): Lighting systems, electronics supply
- **Mid-High Rating (32-63A) Kitchen appliances, air conditioning units, workshop equipment
Installation Guidance
Mounts onto DIN rail (EN 35mm) with ±0.2mm terminal tolerance. Torque terminals to 2.0±0.4 N·m using ring terminals (≤10mm² wire). Always adhere to NEC/IEC 60364 wiring practices.
Compliance
Designed to exceed IEC/EN 60898-1 & IEC/EN 61009-1 performance criteria for residual current devices (RCDs).
Impartial Recommendations
Select ampere ratings based on downstream load:
- Lighting: ≤16A
- Sockets:32A-63A
This safeguard provides industry-compliant Layer-2 protection, resolving circuit integrity compromises without secondary RCD investments.
