Product details

The interrupting ratings are serious: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — so it can handle high-fault utility feeds without cascading upstream.

Thermal derating and sizing

Above that it derates: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. If your panel runs hot, size the load side accordingly.

It ships without auxiliary switches or undervoltage release; the only auxiliary release is the shunt trip (STL). If you need a UVR or ground-fault module, this variant doesn't carry them.

Frequently asked questions

Where can I buy 3VA2340-5HL42-0KA0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What compliance documentation does Siemens provide for 3VA2340-5HL42-0KA0?

As a SENTRON MCCB, it carries UL, CSA, and IEC certifications standard for the series. RoHS and REACH declarations are available from the manufacturer.

Will 3VA2340-5HL42-0KA0 drop into a panel specified around 3VA2225-5HN42-0BB0 without rewiring?

The 3VA2340-5HL42-0KA0 is a 400 A 4-pole frame; the 3VA2225-5HN42-0BB0 is a lower-current variant (225 A). Both share the same SENTRON 3VA platform footprint, so mechanical fit is the same, but the breaker rating and trip unit differ — verify the load side is rated for 400 A before swapping.
