Breaking capacity is the headline: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V. The 53 kA at 690 V still covers most 600 V class industrial feeds. Fitted with the ETU550 electronic trip unit, which offers adjustable response times from 0.5 s to 15 s on the tr parameter, and adjustable N-conductor protection (OFF, 20 % to 100 %). This is a communicating breaker — the Communication Function flag is set — so it integrates with plant monitoring systems for load shedding or fault logging.","metaTitle":"Siemens 3VA2225-8JP42-0AA0 4P MCCB, 250 A, ETU550, 440 kA","metaDescription":"Siemens SENTRON 3VA2225-8JP42-0AA0 molded case circuit breaker, 4-pole line protection, 250 A rated at 40 °C, ETU550 electronic trip, 440 kA at 240 V.
