It carries a maximum interrupting capacity of 187 kA at 240 V and 121 kA at 415 V, so it can clear high-fault currents without upstream coordination issues in most industrial service-entrance or feeder applications. ## Current ratings and thermal derating The breaker holds its full 250 A rating from 40 °C up to 50 °C ambient. Above that, it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. ## Interrupting performance across voltages Breaking capacity drops as system voltage rises: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. For a 480 V delta or 400 V wye service, the 121 kA figure covers most utility transformer sizes. At 690 V the 4.5 kA limit means this breaker is only suitable for low-fault installations or where upstream current-limiting fuses are used. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That 105 mm width is a standard 3-pole MCCB footprint for this class — it fits a typical 200–250 A panelboard or switchboard cubicle without special adapters.","metaTitle":"Siemens 3VA2225-5KP32-0AB0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2225-5KP32-0AB0 molded case circuit breaker, 250 A continuous, 3-pole, 187 kA at 240 V.

The difference is in the internal trip unit and auxiliary options — the 5KP32 variant includes communication function and two auxiliary switches, while the 5HN42 variant does not.
