The 250 A rating holds flat through 50 °C, then derates to 238 A at 55 °C and 200 A at 70 °C, so you don't lose headroom until the ambient climbs past 50 °C. It also carries a communication function, so it can talk to a higher-level control system for status and remote trip indication. The basic switch itself is order code 3VA2225-5KP32-0AA0, and this -0CH0 suffix adds the UVR and communication module. The interrupting ratings step down as 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. The minimum breaking capacity is 375 A, so it's not intended for very low-fault branch circuits. The 105 mm width and 86 mm depth mean it fits standard SENTRON panelboard mounting rails and busbar systems. No special adapters needed for a 3-pole MCCB in a typical distribution panel. The trip indicator is present, so you get a visual flag when the breaker trips — helpful for a maintenance tech walking the line.","metaTitle":"Siemens 3VA2225-5KP32-0CH0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5KP32-0CH0 molded case circuit breaker, 250 A continuous, 3-pole, 187 kA at 240 V.
