The thermal element follows an inverse-time curve — it responds to sustained overcurrents, not inrush — so it's sized for cable protection or as a main breaker in a distribution panel. The magnetic instantaneous element clears hard shorts without intentional delay. Note the N conductor is unprotected on this variant; the neutral pole passes through without a trip element, which is standard for line-side main breakers where the neutral is bonded to ground upstream.","metaTitle":"Siemens 3VA1225-6EE42-0AA0-ZD00 Circuit Breaker, 250A, 70kA","metaDescription":"Siemens 3VA1225-6EE42-0AA0-ZD00 IEC frame 250 circuit breaker. 70kA breaking capacity at 415V, 4-pole, TM220 thermal-magnetic trip.
