Line protection design means it's configured for feeder duty, not motor branch circuit protection. This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. For a 480 V panel (common in North America), the 75.6 kA at 500 V gives headroom above typical 65 kA SCCR requirements. The 3 kA at 690 V is enough for most 690 V motor circuits but won't cover high-fault locations at that voltage. That's unusual for a 40 A frame; most breakers start derating above 40 °C. The ETU350 electronic trip compensates digitally, so you don't lose capacity in a hot panel. Power dissipation is 2.2 W maximum — negligible for panel heat budgeting. Four-pole frame takes up 140 mm of DIN-rail width — standard for a 4-pole MCCB in this class.","metaTitle":"Siemens 3VA2040-5HN46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU35","metaDescription":"Siemens 3VA2040-5HN46-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 4-pole, ETU350 electronic trip, 121 kA breaking at 415 V.
