The breaking capacity climbs to 187 kA at 240 V AC, drops to 121 kA at 415 V, 76 kA at 440 V, and 17 kA at 500 V. The 17 kA at 500 V still covers most industrial distribution needs.
Rated insulation voltage Ui is 690 V, max operational voltage with DC is 500 V. The 40 A rating holds steady from 40 °C up to 50 °C, then derates to 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C. Plan the load accordingly. No field-adjustable dials — what you order is what you get. N-conductor protection is rated at 100%.
That said, if you're doing a new panel design, the 3VA series (e.g., 3VA1110-5EE32-0JA0) is the current-generation sibling with a wider accessory ecosystem and electronic trip options. The 3VM1 is still a valid BOM line for existing designs or where a thermal-magnetic fixed-release is exactly what the spec calls for.
What's in the box — and what's not
This is a bare breaker — line protection only. Power loss is 10.8 W maximum at rated current. Mechanical endurance is 12,000 operations.
