The short-circuit protection is fixed at 12.8 × In (320 A magnetic pickup), so it's sized for general line protection, not motor starting where you'd want a higher multiple to avoid nuisance trips on inrush. ## Deployment context This breaker mounts in a standard IEC distribution panel or enclosure. The 4-pole configuration with a solid-neutral path means it's suited for 3-phase + N systems where you want overcurrent protection on the phases only.","metaTitle":"Siemens 3VA1125-4ED42-0AA0-ZD00 Circuit Breaker, 25A, 36kA @","metaDescription":"Siemens 3VA1125-4ED42-0AA0-ZD00 IEC frame 160 circuit breaker, 25A, 36kA breaking capacity @ 415V.
