At 690 V it still interrupts 4.5 kA, covering most industrial motor circuits. Front protection is IP40, so the breaker face is protected against tools and small debris but not washdown. Power loss is 48 W maximum at rated current — factor that into enclosure ventilation, especially when multiple breakers are ganged in a single section. ## Trip unit and protection features The ETU350 electronic trip unit supports LSIG protection (long-time, short-time, instantaneous, and ground-fault) but this variant ships without ground-fault monitoring. No undervoltage release, no voltage trigger, and no communication function are fitted on this order code.","metaTitle":"Siemens 3VA2225-6HN42-0AA0 SENTRON MCCB, 250 A, 4-Pole, 242","metaDescription":"Siemens 3VA2225-6HN42-0AA0 SENTRON molded case circuit breaker. 250 A continuous, 4-pole, 242 kA at 240 V.
