That flat thermal curve simplifies panel sizing: the breaker delivers its nameplate 800 A in most standard enclosure conditions without recalculating. Interrupting ratings hit 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — figures that cover high-fault infrastructure like transformer secondaries or large motor control centers. The ETU350 electronic release allows adjustable long-time pickup (Ir) up to 800 A and instantaneous pickup (Ii) up to 8 000 A, plus short-time delay (tsd) from 0.04 s to 0.4 s. Mounts in a standard panel footprint: 210 mm wide, 320 mm tall, 120 mm deep. No communication module or ground-fault monitoring is built in — this is a straight line-protection device.","metaTitle":"Siemens 3VA2580-5HN32-0KC0 SENTRON MCCB, 800 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2580-5HN32-0KC0 molded case circuit breaker, 3-pole, 800 A rated continuous current, interrupting 187 kA at 240 V.
