Product details

The 3VA1032-4ED32-0KA0: The interrupting rating drops with system voltage: 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The thermal rating holds 32 A flat from 40 °C to 50 °C, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. For a panel running at 55 °C ambient, you lose 1 A of headroom.

The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint. It fits a 3-pole slot in a SENTRON distribution panel or any 76.2 mm-wide DIN-rail mount.

Frequently asked questions

Where can I buy 3VA1032-4ED32-0KA0 and how do I get a price?

It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is 3VA1032-4ED32-0KA0's listed depth?

The listed depth is 70 mm.

What is 3VA1032-4ED32-0KA0's listed width?

The listed width is 76.2 mm.

Will 3VA1032-4ED32-0KA0 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?

Both breakers share the same 3-pole SENTRON family footprint (76.2 mm wide, 130 mm tall, 70 mm deep), so the physical swap fits. However, the 3VA1110-5ED36-0AC0 is a higher-current variant with different trip characteristics; verify the load rating and interrupting requirements before substituting.
