Product details

What this 4-pole MCCB delivers in the panel

The Siemens SENTRON 3VM1340-4GE42-0AA0 is a 4-pole molded case circuit breaker sized for line protection at 400 A continuous (rated at 40 °C, no derating needed until you cross 55 °C). Interrupting capacity is 121 kA at 240 V AC and 76 kA at 415/440 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream. At 55 °C it's 392 A; at 60 °C, 384 A; at 65 °C, 376 A; at 70 °C, 367 A.

Fit and footprint

The case measures 248 mm high, 184 mm wide, 110 mm deep. Four-pole width at 184 mm is standard for this class; verify the gland-plate knockout pattern and bus-bar centers before drilling the backplate.

Frequently asked questions

Where can I buy 3VM1340-4GE42-0AA0 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 through the storefront.

What does the TM220 overcurrent release mean for coordination?

TM220 is a thermal-magnetic release — the thermal element follows an inverse-time curve for overloads, and the magnetic element trips instantaneously on short-circuit. It is a fixed-trip design, not electronic, so selectivity with downstream breakers depends on the magnetic pickup level and the upstream breaker's instantaneous threshold.

What compliance documentation does this brand provide for 3VM1340-4GE42-0AA0?

Siemens SENTRON series MCCBs typically carry IEC/EN 60947-2 certification and UL 489 listing. RoHS and REACH declarations are available through the manufacturer's documentation portal. Specific certs for this order code should be confirmed from the nameplate or the Siemens Industry Online Support download area.
