At 690 V the rating drops to 4.5 kA, so this breaker is sized for low-voltage distribution up to 690 V but the high interrupting performance lives below 500 V. The ETU850 release is the decision point here: it offers adjustable long-time (tr 0.5–15 s), short-time (tsd max 0.5 s), and instantaneous protection, plus communication capability for power monitoring. The N-conductor protection is adjustable from OFF through 20% to 100% of the phase current — useful on 4-wire systems where neutral protection must match the load balance. ## Sourcing and lifecycle — current production, quoted to order For buyers comparing against the 5SQ2670-2YA06 or 5SQ2670-2YA63: those are different frame families (5SQ series, not 3VA). The 3VA2225-6KP42-0LA0 will not drop into a panel wired for a 5SQ breaker without rewiring. ## Thermal derating and selectivity planning At 55 °C it derates to 238 A, at 60 °C to 225 A, at 65 °C to 213 A, and at 70 °C to 200 A. The 800 V rated insulation voltage (Ui) gives headroom for 690 V systems, but the interrupting capacity at 690 V (4.5 kA) is low — coordinate with an upstream fuse or current-limiting breaker for high-fault locations.","metaTitle":"3VA2225-6KP42-0LA0 SENTRON MCCB, 250 A, 4-pole, ETU850, 242","metaDescription":"Siemens SENTRON 3VA2225-6KP42-0LA0 molded case circuit breaker, 250 A, 4-pole, ETU850 electronic release, 242 kA at 240 V.
