Product details

The Siemens 3VA2140-8HN32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 40 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.

This MCCB carries a short-circuit breaking capacity of 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. The 800 V rated insulation voltage gives headroom for 480 V and 600 V class systems.

Dimensions are 86 mm deep, 105 mm wide, 181 mm tall — a standard MCCB footprint for 3-pole frames in this class. Power loss is a modest 1.2 W maximum, so heat buildup in a dense cabinet is minimal.

Frequently asked questions

Where can I buy 3VA2140-8HN32-0AA0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 3VA2140-8HN32-0AA0?

The 3VA2040-8HN42-0AA0 is a sibling in the same SENTRON family, but it uses a different trip unit variant (ETU420 vs ETU350). Verify the trip curve and accessory compatibility before substituting — the frame and pole count match, but the protection profile differs.

Will 3VA2140-8HN32-0AA0 drop into a panel specified around 3VA2040-8HN42-0AA0 without rewiring?

The frame dimensions and pole count are identical, so the mechanical fit and bus-bar spacing are the same. However, the trip unit differs (ETU350 vs ETU420), so the protection settings and coordination study may need review. No rewiring required if the lug kit and accessory positions match.
