Breaking capacity is 242 kA at 240 V AC and 187 kA at 415 V AC — figures that place this MCCB in the high-interrupting-capacity tier, suitable for fault-current-intensive installations like transformer secondaries or large motor control centers where upstream coordination demands headroom. Rated current holds flat at 40 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel design in hot environments. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without rework. Front face carries IP40 protection, adequate for enclosed switchboards. The ETU550 release is a microprocessor-based unit with communication capability — integrates with higher-level monitoring systems for trip data and status without requiring an undervoltage release. Optional motor drive available for remote charging and closing — useful for automated transfer schemes or SCADA-controlled feeders. ## Ratings & Coordination Insulation voltage is rated 800 V (Ui), so the breaker can be applied in 690 V systems where the 3 kA breaking capacity at 690 V governs the fault level at that voltage. Power loss is 2.2 W maximum — low enough that ventilation requirements are minimal in a standard enclosure.","metaTitle":"Siemens SENTRON 3VA2040-6JP32-0AA0 MCCB, 40 A, 242 kA at 240","metaDescription":"Siemens SENTRON 3VA2040-6JP32-0AA0 molded case circuit breaker, 40 A, 3-pole, ETU550 release, 242 kA at 240 V.
