Product details

What this MCCB rating means for your panel

Its interrupting capacity hits 330 kA at 240 VAC and 242 kA at both 415 V and 440 V — that's the fault current it can safely clear without welding contacts or venting plasma.

Above that, derate linearly: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. Maximum power loss is 96 W, which matters for ventilation planning in sealed enclosures.

Panel fit — dimensions and auxiliaries

The supplied basic switch variant is 3VA2340-7HN32-0AA0. If your panel spec calls for shunt trip or ground-fault, this base variant won't have it — you'd need a different suffix.

Frequently asked questions

Where can I buy 3VA2340-7HN32-0AB0 and how is it quoted?

This MCCB is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for your target volume and delivery window.

Will 3VA2340-7HN32-0AB0 drop into a panel specified for 5SQ2370-2YA05?

The 3VA2340-7HN32-0AB0 is a Siemens SENTRON frame; the 5SQ2370-2YA05 is a different manufacturer's MCCB. Dimensions, mounting pattern, and terminal spacing differ — do not assume mechanical interchangeability without comparing the panel cutout and bus connection layout.
