At 500 V the rating drops to 121 kA, and at 690 V it is 3 kA — the latter limits application to low-fault systems or downstream positions at that voltage. ## Thermal performance and trip unit The 40 A continuous rating holds across the full ambient range from 40 °C to 70 °C, meaning no derating is needed in a warm enclosure. ## Physical integration At 181 mm high, 140 mm wide, and 86 mm deep, this 4-pole MCCB fits standard SENTRON mounting patterns.","metaTitle":"Siemens 3VA2040-6JP46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU55","metaDescription":"Siemens 3VA2040-6JP46-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 4-pole, ETU550 electronic trip unit.
