Three-pole, rated 200 A continuous (Iu), with an ETU310M electronic trip unit that gives you adjustable overload and short-circuit protection curves. The 200 A rating holds flat from 40 °C up to 50 °C, then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. If your panel ambient runs hot — say a non-ventilated enclosure next to a furnace line — that derating curve tells you exactly where you land without guessing. Breaking capacity is the headline number here: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 52.5 kA at 690 V. That 330 kA figure at 240 V means it can safely interrupt a fault up to that level without the arc flashing over or the case rupturing — critical for high-fault installations like transformer secondaries or large motor control centers. ## Trip unit and accessories — what's inside the case The ETU310M is a microprocessor-based release with LSI (long-time, short-time, instantaneous) protection. It's adjustable, so you can set the pickup and delay to coordinate with downstream feeders. The breaker ships with a shunt trip (STL) for remote opening, plus a full auxiliary contact block: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ). That's enough status feedback for a PLC input card without adding a separate relay. The basic switch assembly is order code 3VA2220-7MS32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL33 — useful to know if you're ordering spare parts or building a kit. No undervoltage release, no phase-failure detection, no communication module on this variant. It's a straight protection device, not a smart breaker. ## Physical fit — panel and enclosure Dimensions: 181 mm high, 105 mm wide, 86 mm deep. That 105 mm width is three-pole wide — standard for a 200 A frame MCCB. Mounts on a DIN rail or direct-panel via the screw terminals. The 86 mm depth means it fits in a 200 mm deep enclosure with room for wiring gutters. Verify the mounting footprint against your existing bus bars or cable lugs before committing the panel layout.","metaTitle":"Siemens 3VA2220-7MS32-0KL0 SENTRON MCCB, 200 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2220-7MS32-0KL0 molded case circuit breaker, 200 A rated, 330 kA breaking at 240 V.
