If the panel ambient hits 50 °C, the breaker is good for 593 A continuous — a 6% reduction that must be factored into the load schedule. ## Environmental and endurance limits Mechanical endurance is 15,000 operations, typical for a fixed-mount MCCB in main distribution.","metaTitle":"Siemens 3VA2463-6HN32-0JC0 SENTRON MCCB, 630 A, 242 kA at 24","metaDescription":"Siemens 3VA2463-6HN32-0JC0 SENTRON molded case circuit breaker, 630 A rated, 242 kA interrupting at 240 V, 3-pole, ETU350 release, line protection.
