Breaking capacity reaches 242 kA at 240 V, 187 kA at 415 V, and 4.5 kA at 690 V (cites:,). ## Current derating and thermal limits At 55 °C it derates to 240.625 A, at 60 °C to 231.25 A, at 65 °C to 221.875 A, and at 70 °C to 212.5 A (cites:,). The maximum power loss is 55 W (cites:). The ETU850 electronic trip unit (cites:) supports communication functions (cites:) and other measurement functions (cites:), which means it can integrate with a BMS or energy monitoring system — not just a passive breaker. The basic switch is order code 3VA2225-6KP42-0AA0 (cites:); the integrated auxiliary trip is 3VA9688-0BL30 (cites:). A voltage trigger is present (cites:); undervoltage release is not fitted (cites:). Phase failure detection is not included (cites:). Front protection is IP40 (cites:) — suitable for a dry indoor panel; not rated for washdown.","metaTitle":"Siemens 3VA2225-6KP42-0HG0 SENTRON MCCB, 250 A, 4-Pole, ETU8","metaDescription":"Siemens 3VA2225-6KP42-0HG0 SENTRON molded case circuit breaker, 250 A rated continuous current, 4-pole, ETU850 electronic trip, breaking capacity 242 kA at 240 V.
