What this 3VA2 frame 250 MCCB carries
The Siemens 3VA2225-6KP42-0KK0 is a 4-pole IEC frame 250 molded case circuit breaker with breaking capacity class H, rated Icu=85kA at 415 V AC. 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.
What the ratings mean for fit
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.
