What this 3VA2225-7KP32-0DL0 is and what it does
The Siemens 3VA2225-7KP32-0DL0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current across a 3-pole configuration. It's designed for line protection in distribution panels, with an interrupting capacity that reaches 330 kA at 240 V AC and holds 242 kA at 415 V and 440 V, then steps down to 187 kA at 500 V and 4.5 kA at 690 V. That SCCR range tells you this breaker is built for high-fault industrial mains, not branch circuits — the 330 kA at 240 V is typical for transformer secondary protection where available fault current is high.
Ratings that decide fit
Continuous current holds at 250 A from 40 °C through 50 °C ambient, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. That means in a warm enclosure — say a non-ventilated panel near a furnace line — you lose 50 A off the nameplate. Size the load at the actual ambient, not the 40 °C sticker. The interrupting ratings are given per voltage level, so selectivity coordination studies need the specific fault current at the point of installation. Power loss is 50.5 W maximum at rated load. That's heat that stays inside the enclosure; factor it into the panel thermal budget if you're stacking several breakers in a confined space.
Auxiliaries and communication
This MCCB ships with an undervoltage release (UVR) and a complement of auxiliary switches: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ design). The trip indicator is present, and a communication function is built in — that means it can report status or trip events to a monitoring system without an external module. The basic switch variant is 3VA2225-7KP32-0AA0, so if you need a bare breaker without auxiliaries, that's the base order code.
Physical fit and environment
Dimensions: 86 mm depth, 105 mm width, 181 mm height. That 105 mm width is the standard 3-pole MCCB footprint for this SENTRON frame size — it fits existing 3VA panel cutouts and busbar arrangements without adapter plates. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. No IP rating is listed on this record, so it's intended for enclosed panel mounting, not washdown or outdoor exposure.
