Breaking capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 6.3 kA at 690 V. That matters when you need selective coordination downstream or want to dial in the trip for motor or transformer inrush without nuisance trips. The shunt trip is the only auxiliary release fitted. Maximum power dissipation is 48 W at rated current. ## What this variant includes — and what it skips Line protection version (not motor protection — no phase-failure detection, no undervoltage release). The shunt trip (STL) is the only auxiliary release; its basic switch is order code 3VA2225-7HN32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL33. The ETU350 is self-powered from the line current; no external control power needed for the trip unit itself (the shunt trip does need a separate control voltage).","metaTitle":"Siemens 3VA2225-7HN32-0KA0 SENTRON MCCB, 250 A, 3-Pole, Shun","metaDescription":"Siemens SENTRON 3VA2225-7HN32-0KA0 molded case circuit breaker, 250 A rated continuous current, 3-pole, ETU350 release, shunt trip.
