The Siemens SENTRON 3VA2510-6JP42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 1000 A at 40 °C ambient, with no derating required up to 55 °C — the full 1000 A holds across that band. At 60 °C the rating steps to 955 A, then 885 A at 65 °C, and 815 A at 70 °C, per the published thermal curve. Breaking capacity is specified across five voltage points: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 73.5 kA at 690 V. Maximum power loss is 330 W.
Dimensions are 320 mm height, 280 mm width, and 120 mm depth. The 280 mm width is the critical panel cutout dimension — verify against existing busbar or mounting footprint before committing the gland plate layout.
