Breaking capacity is the real differentiator here. At 240 V AC this breaker interrupts 440 kA — that's utility-grade fault current, typical for large transformer secondaries or industrial service entrances. At 415 V and 440 V it still handles 330 kA, and at 500 V it's 220 kA. Even at 690 V it manages 52.5 kA. Those numbers mean you can place this MCCB on a high-fault bus without worrying about cascading failure upstream. That's a standard SENTRON 3VA footprint — it bolts into the same mounting pattern as other 3VA frame breakers. Power loss is only 1.2 W at rated load, so heat buildup in a dense panel is minimal.","metaTitle":"Siemens 3VA2140-8HN36-0AA0 MCCB, 40 A, 3-Pole, 480 A Frame,","metaDescription":"Siemens SENTRON 3VA2140-8HN36-0AA0 molded case circuit breaker. 40 A continuous, 3-pole, 480 A frame, ETU350 release.
