Its interrupting capacity reaches 242 kA at 240 V, 187 kA at 415 V, and 74 kA at 690 V — figures that place it in the high-fault-duty class for large industrial feeders and switchboards. The ETU350 electronic trip unit provides adjustable long-time (Ir 0.5–1.0× In, tr 0.5–17 s), short-time (Isd, tsd 0.04–0.4 s), and instantaneous (Ii up to 8000 A) protection curves, giving the commissioning engineer selectivity headroom downstream. Dimensions are 320 mm height, 210 mm width, 120 mm depth — a standard MCCB footprint for 800 A class. The IP40 front protection suits enclosed panel mounting; no external washdown rating, so keep it inside the cabinet. ## What the ETU350 trip unit means for coordination The ETU350 is a programmable electronic trip unit, not a fixed thermal-magnetic. That means the site electrical engineer can shape the time-current curve — set long-time pickup (Ir) anywhere from 400 A to 800 A, short-time delay up to 0.4 s, and instantaneous pickup up to 8000 A — to achieve selective coordination with downstream breakers. Maximum power loss is 135 W at rated current — a figure the panel designer uses for thermal budgeting inside the enclosure.","metaTitle":"Siemens 3VA2580-6HN32-0AJ0 MCCB, 800 A, 242 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2580-6HN32-0AJ0 molded case circuit breaker, 800 A rated, 242 kA at 240 V.
