The Siemens SENTRON 3VA2225-6JP32-0LK0 is a 3-pole molded case circuit breaker rated 250 A continuous at 40 °C, with an ETU550 electronic trip unit configured for line protection. The 105 mm width and 181 mm height match the standard SENTRON 3VA frame footprint, so it swaps into an existing 3VA panel cutout without re-drilling the gland plate.
Full 250 A rating holds through 50 °C ambient. Above that it derates linearly: 238 A at 55 °C, 225 A at 60 °C, down to 200 A at 70 °C.
86 mm (3.39 in).
105 mm (4.13 in).
