Product details

The Siemens SENTRON 3VA1340-4EF32-0DE0 is a 3-pole molded case circuit breaker rated for continuous 400 A at 40 °C, with a 121 kA interrupting capacity at 240 V.

Breaking capacity across voltage

This MCCB delivers 75.6 kA at 415 V and 440 V, 52.5 kA at 500 V, and 11.9 kA at 690 V. The steep drop above 500 V means it's best suited for 240–480 V systems where the SCCR headroom is generous.

Integration and accessories

No communication function onboard — this is a standalone line protection breaker, not a smart metering device.

Frequently asked questions

Where can I buy 3VA1340-4EF32-0DE0 and what is the lead time?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead time is published here.

What is the breaking capacity of this MCCB at 240 V?

121 kA at 240 V, which covers high-fault utility feeds in most North American 240 V panels.

Does 3VA1340-4EF32-0DE0 include an undervoltage release?

Yes, it ships with an undervoltage release (UVR) fitted, plus 4 auxiliary switches HQ.
