The Siemens 3VA2580-6HL32-0KA0 is a SENTRON molded case circuit breaker (MCCB) rated for 800 A continuous current at 40 °C through 60 °C, derating to 767 A at 65 °C and 703 A at 70 °C — so the full 800 A holds across typical panel ambient, and you only lose headroom above 60 °C. The 242 kA breaking capacity at 240 V and 187 kA at 415 V mean this breaker can interrupt faults up to those levels without upstream cascading; at 690 V it still clears 74 kA. That SCCR range covers most industrial service-entrance and feeder applications. The ETU320 overcurrent release provides LI (long-time and instantaneous) protection, with adjustable long-time pickup (lg) from 800 A to 8000 A and instantaneous pickup (li) from 1200 A to 8000 A — you set the trip curve to coordinate with downstream devices.
The 3VA2580-6HL32-0KA0 measures 210 mm wide, 320 mm high, and 120 mm deep — a 3-pole frame that fits standard MCCB cutouts in switchboards and panelboards.
