That 242 kA at 240 V is high for a 63 A frame — it means this breaker can be applied on high-fault-current services (large transformers, utility tie points) where a standard 25 kA or 65 kA MCCB would fail to interrupt a bolted fault. The steep drop to 3.7 kA at 690 V is typical for a 4-pole breaker in a 690 V system; verify the available fault current at that voltage before specifying. That simplifies panel layout — no need to upsize the frame for a warm enclosure. The ETU340 trip unit is field-adjustable for long-time pickup, short-time pickup, and instantaneous settings. No communication function or voltage-trigger accessory is built in — coordination studies rely on the trip curve alone. The power loss is 4 W maximum, negligible for panel thermal budgeting.","metaTitle":"Siemens 3VA2163-6HK42-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU34","metaDescription":"Siemens SENTRON 3VA2163-6HK42-0AA0 molded case circuit breaker, 63 A rated, 4-pole, ETU340 trip unit.
