The Siemens SENTRON 3VA2580-5HL32-0AF0 is a 3-pole molded case circuit breaker rated for 800 A continuous current at 40 °C, with a rated insulation voltage of 800 V. Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — figures that put it in the high-interrupting tier for large-distribution main breakers or heavy industrial feeds where fault currents are substantial. The breaker carries an ETU320 electronic trip unit with adjustable long-time pickup (Ir) from 320 A to 800 A and instantaneous pickup (Ii) from 1200 A to 8000 A, giving the site engineer selectivity tuning across a wide range.
The breaker measures 210 mm wide, 320 mm high, and 120 mm deep — a footprint that fits standard SENTRON 3VA panel cutouts and bus-bar centers. The 3-pole design with line protection version (no ground-fault module) keeps wiring straightforward for main feeder or large motor branch applications.
