Two high-performance auxiliary switches (HQ) are integrated for status feedback to the PLC or SCADA system. ## What the interrupting ratings mean for coordination At 240 V this breaker clears 187 kA symmetrical — that's a utility-side fault level typical of a large transformer secondary or a generator bus. The drop to 79 kA at 500 V and 5.1 kA at 690 V is expected for a frame this size; if your system runs 690 V and fault current exceeds that, you need a higher-rated frame. At 55 °C it derates to 241 A, then 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. The 140 mm width, 181 mm height, and 86 mm depth fit standard SENTRON mounting patterns — it drops into the same cutout as other 3VA2 frames, so a panel laid out for a 3VA2225-5HN42-0BB0 takes this unit without re-drilling. ## Protection and control features The ETU350 electronic trip unit provides LSIG protection (long-time, short-time, instantaneous, ground-fault) with adjustable settings. The shunt trip (STL) allows remote tripping from a safety relay or emergency-stop circuit. Two HQ auxiliary switches report breaker position — one for open/closed status, the second for trip indication.","metaTitle":"Siemens 3VA2225-5HN42-0JC0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0JC0 molded case circuit breaker, 250 A rated continuous current, 4-pole, interrupting capacity 187 kA at 240 V.
