At 415 V and 440 V it holds 187 kA, dropping to 121 kA at 500 V and 9 kA at 690 V — the 690 V figure is the weak leg, so verify your line voltage against that curve before specifying. Physical footprint: 184 mm wide, 248 mm tall, 110 mm deep (–). That 184 mm width is a 4-pole frame — it needs a full 7.24 inches of DIN-rail or panel-mount space, so check your backpan layout before committing. Max power loss is 162 W, which adds to the enclosure thermal budget — account for that when sizing ventilation or cooling.","metaTitle":"SENTRON 3VA2463-6HN42-0KF0 MCCB, 630 A, 4-Pole, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-6HN42-0KF0 molded case circuit breaker, 630 A continuous, 4-pole. 242 kA breaking at 240 V, derated to 520 A at 70 °C.
