The 250 A continuous rating holds flat from 40 °C through 50 °C, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. At 240 V it handles 187 kA, which covers most North American secondary distribution; at 690 V it drops to 4.5 kA, so on a 690 V system you must verify the available fault current is below that threshold. The breaker carries a communication function, meaning it can report status or trip events to a higher-level control system — useful for remote monitoring in a managed distribution scheme. The breaker ships with 4 auxiliary switches HQ and is configured without undervoltage release or ground-fault monitoring.","metaTitle":"Siemens 3VA2225-5KP32-0AE0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5KP32-0AE0 molded case circuit breaker, 250 A continuous, 3-pole, 187 kA interrupting at 240 V.
