That class H rating means it handles high prospective fault currents typical of industrial main feeders or large sub-distribution boards — not a panelboard branch breaker. The electronic trip unit is an ETU850 with LSI protection: long-time (Ir) adjustable 100 A to 250 A, short-time (Isd) 0.6–10× In, and instantaneous (Ii) 1.5–10× In. Neutral conductor protection is adjustable from OFF up to 100% of the phase setting. The breaker ships with a factory-installed shunt trip on the left side, rated 208–277 V AC 50/60 Hz and 220–250 V DC, plus one auxiliary switch changeover H and one trip alarm switch changeover (electrical alarm switch HQ). A nut keeper kit is included for the mounting hardware. This is a fully populated accessory configuration — no need to order add-on modules separately for remote trip and status feedback. The shunt trip operates on AC 208–277 V or DC 220–250 V. The auxiliary switch changeover H provides a Form C contact for remote status; the trip alarm switch changeover signals fault opening.","metaTitle":"Siemens 3VA2225-6KP42-0KK0 250A MCCB, 85kA @ 415V","metaDescription":"Siemens 3VA2225-6KP42-0KK0 IEC frame 250 MCCB, breaking capacity class H Icu=85kA @ 415V, ETU850 LSI, In=250A, shunt trip, aux switches.
