That 800 A frame holds steady across a wide temperature band, so you don't lose capacity in a warm enclosure. The interrupting ratings are the headline: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 74 kA at 690 V. It carries an ETU340 electronic trip unit — that's the adjustable long-time, short-time, instantaneous, and ground-fault capable tier in the 3VA line. The rated continuous current Iu matches the Ir max at 800 A, and the N-conductor protection is adjustable: OFF, 50%, or 100% of the phase current. That lets you tune for 3-pole or 4-pole protection without swapping hardware. The power loss maxes at 231 W — factor that into your enclosure thermal budget if you're stacking multiple breakers in a tight MCC bucket. ## Physical fit and mounting Dimensions are 280 mm wide, 320 mm tall, and 120 mm deep — that's 11 by 12.6 by 4.7 inches. It's a 4-pole frame, so it takes up the full width of a typical MCC bucket or a 600 mm wide enclosure.","metaTitle":"Siemens 3VA2580-6HK42-0AA0 SENTRON MCCB, 800 A, 4-Pole, 242","metaDescription":"Siemens SENTRON 3VA2580-6HK42-0AA0 molded case circuit breaker, 800 A continuous, 4-pole, 242 kA at 240 V.
