The short-circuit protection is fixed at 10 × In (630 A magnetic pickup), so it's sized for general cable and light motor protection — not for high-inrush transformer or heavy motor starting where a higher Ii setting would be needed. ## What the N conductor unprotected means The description flags N conductor unprotected — the neutral pole on this 4-pole breaker is a switched-only pole (no overcurrent protection). That's standard for most 3-phase + N distribution where the neutral is not expected to carry fault current. If your panel design requires a fully protected neutral (TN-C systems, high-harmonic loads), this isn't the variant you want.","metaTitle":"Siemens 3VA1163-3ED42-0AA0-ZD00 Circuit Breaker, 63A, 25kA @","metaDescription":"Siemens 3VA1163-3ED42-0AA0-ZD00 IEC frame 160 MCCB, 63A fixed TM trip, 25kA Icu @ 415V, 4-pole, current lifecycle.
