Product details

Line protection MCCB, 400 A frame, 4-pole

At 415 VAC the interrupt rating holds at 121 kA, so it handles industrial 400 V distribution without cascading upstream breakers in most configurations.

Breaking capacity by voltage level

This MCCB delivers 187 kA at 240 VAC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V.

Panel fit and auxiliary configuration

The breaker ships without an undervoltage release or ground-fault monitoring module; those are field-addable options if the application requires shunt-trip or GF protection. The four HQ auxiliary switches provide status feedback for PLC inputs or remote indication without needing a separate accessory.

Frequently asked questions

Where can I buy 3VA2340-5HN42-0AE0 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 — submit an RFQ to receive a firm price and lead-time estimate.

What is the breaking capacity of this MCCB at 415 V?

At 415 VAC the interrupting rating is 121 kA, matching the 440 V rating. At 240 VAC it reaches 187 kA.

What auxiliary switches are fitted on this variant?

This -0AE0 suffix includes four HQ auxiliary switches factory-installed. No undervoltage release or ground-fault monitoring is included.
