Frequently asked questions
Will 3VM1020-2ED42-0AA0 drop into a panel designed for 3VA1020-3ED36-0AA0?
The 3VM series is the predecessor to the 3VA series; they share the same 4-pole footprint (101.6 mm width) and similar mounting pattern, but the 3VA has an electronic release versus the fixed TM210 thermal-magnetic on this 3VM. Panel cutouts and busbar spacing are compatible, but verify the trip curve and auxiliary contact arrangement before swapping — the 3VA offers adjustable Ir and more accessory slots.
Its 20 A continuous current holds flat from 40 °C to 55 °C — no derating needed in a typical warm panel — then drops to 19 A at 60 °C and 18 A at 70 °C. That thermal curve matters when you're packing breakers side-by-side in a distribution board; the 12 W maximum power loss per unit adds up in a dense enclosure. Breaking capacity is the headline: 53 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V. The 690 V rated insulation voltage (Ui) confirms it's built for 400/480 VAC systems with headroom.
Dimensions: 70 mm deep, 101.6 mm wide, 130 mm high. 101.6 mm width (4 inches) is the standard 4-pole MCCB footprint. IP40 on the front. Mechanical endurance rated at 10,000 operations.
