The 500 A continuous rating holds up to 50 °C ambient; above that it derates to 477 A at 55 °C, 455 A at 60 °C, 432 A at 65 °C, and 410 A at 70 °C. A panel OEM wireman should account for the 99 W maximum power loss when sizing enclosure ventilation. Dimensions are 248 mm height, 184 mm width, and 110 mm depth — a standard SENTRON 3VA2 frame footprint that drops into existing panel cutouts and DIN-rail mounting schemes. The 4-pole configuration with no undervoltage release and no communication module keeps wiring straightforward for the panel builder.","metaTitle":"Siemens 3VA2450-5HK42-0AA0 SENTRON MCCB, 500 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2450-5HK42-0AA0 molded case circuit breaker, 500 A continuous, 4-pole, ETU340 trip unit.
