The Siemens SENTRON 3VA2580-5HL32-0CL0 is a 3-pole molded case circuit breaker rated for 800 A continuous current at 40 °C, with an ETU320 electronic trip unit. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — numbers that put it in the high-fault tier for industrial main feeders or large sub-distribution.
Thermal derating and trip settings
The ETU320 release gives you adjustable long-time pickup (Ir) from 320 A to 800 A, short-time pickup (li) from 1200 A to 8000 A, and long-time delay (tr) from 0.5 to 17 seconds. That range covers motor feeders, transformer primaries, and general distribution where you need to ride through inrush without nuisance trips.
