At 690 V AC the same breaker still handles 187 kA, which covers most 690 V industrial grids. ## Panel integration — dimensions and mounting Maximum power loss is 1.2 W — negligible for panel heat budgeting, but worth noting if you're packing many breakers in a sealed enclosure. ## Trip unit and protection features The N-conductor protection is adjustable from OFF to 40%–160% of the rated current, giving flexibility for systems with partial or full neutral protection. This variant does not include undervoltage release, ground-fault monitoring, or a trip indicator. If those functions are needed on the same BOM, you'd add them as external modules or select a different 3VA2 option code. Grounding protection is also absent — this is a line-protection breaker, not a GFCI device.","metaTitle":"Siemens 3VA2140-0KP36-0AA0 SENTRON MCCB, 40 A, ETU850, 440 k","metaDescription":"Siemens 3VA2140-0KP36-0AA0 SENTRON molded case circuit breaker, 40 A continuous, ETU850 electronic trip, 440 kA at 415 V.
