The interrupting ratings are 65 kA at 240 V AC and 25 kA at 480 V AC — that 65 kA figure at 240 V is the headline number for high-fault panels fed from a 240 V service transformer, while the 25 kA at 480 V covers most 480 V distribution boards without needing a current-limiting upstream breaker. Derate it as the ambient climbs: 39 A at 45 °C, 38 A at 55 °C, 37 A at 60 °C, 36 A at 65–70 °C — useful if this breaker lands in a crowded enclosure with other heat sources. The 3VA4140-4ED34-0AA0 measures 76.2 mm wide, 129.4 mm tall, and 75.1 mm deep — a standard 3-pole MCCB footprint that drops into most DIN-rail or panel-mount enclosures without re-drilling. With 65 kA interrupting at 240 V and 25 kA at 480 V, this MCCB provides full-rated SCCR for most 240 V and 480 V distribution panels. The 25 kA at 480 Y/277 V and 14 kA at 600 Y/347 V cover wye-grounded systems.","metaTitle":"Siemens 3VA4140-4ED34-0AA0 SENTRON MCCB, 40 A, 65 kA at 240","metaDescription":"Siemens 3VA4140-4ED34-0AA0 SENTRON 3-pole MCCB, 40 A rated at 40 °C, 65 kA interrupting at 240 V.
