The interrupting ratings tell you where it'll hold: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, dropping to 5.1 kA at 690 V. Thermal derating is real and published: full 250 A up to 50 °C ambient, then 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C. If your panel runs hot, size the load accordingly — don't count on 250 A above 50 °C. Bolts into a distribution panel or switchboard; no DIN-rail mounting on this frame, it's screw-fixed. The shunt trip (STL) release is built in, part of the -0JH0 suffix. ## What's inside — subcomponents matter The basic switch is 3VA2225-5HN32-0AA0; the integrated auxiliary trip is 3VA9688-0BL32. If you're stocking spares or replacing just the trip unit, those are the order codes to cross-reference. Max power loss is 48 W — account for that in panel thermal calcs.","metaTitle":"Siemens 3VA2225-5HN32-0JH0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2225-5HN32-0JH0 molded case circuit breaker, 250 A rated, 3-pole, line protection with ETU350 electronic trip unit. 187 kA at 240 V.
