That flat thermal performance is unusual for an MCCB this size; most breakers start backing off above 40 °C. The interrupting ratings are what drive the selection: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3 kA at 690 V (–). At 690 V the 3 kA rating tells you this is not a 690 V main breaker; it's a line/feeder breaker on lower-voltage distribution. That 140 mm width for a 4-pole 100 A MCCB is compact — it fits a standard 600 mm wide enclosure with room for side-feed lugs or a shunt trip accessory.","metaTitle":"Siemens 3VA2010-7HN42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2010-7HN42-0AA0 SENTRON molded case circuit breaker, 100 A continuous, 4-pole, ETU350 electronic trip, 330 kA at 240 V.
