Its ETU850 electronic trip unit gives you adjustable overload and short-circuit protection with a continuous current rating of 40 A, sitting inside a frame rated for 60 A minimum to 480 A maximum — meaning the same physical breaker shell can be ordered with different trip units across the range, but this specific variant is set for 40 A continuous duty. 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.
