The 300 mA IΔn is the earth-leakage trip threshold; at that level it's typically specified for circuits where a lower 30 mA threshold would cause nuisance tripping — think distribution boards feeding multiple socket outlets or fixed equipment with natural leakage. ## Deployment context The 1+N-pole format (switched phase plus switched neutral) means it isolates both conductors on fault, which is required in many national wiring regulations for final circuits. The 70 mm width is a common module size for RCBOs in European-style consumer units.","metaTitle":"Siemens 5SU1654-6KV20 RCBO Type A, 300mA, 10kA, 1+N B 20A","metaDescription":"Siemens 5SU1654-6KV20 FI/LS protector Type A (PSE/SSF), 300mA, 10kA, 1+N-pole B 20A.
