Product details

That matters when you're coordinating downstream breakers on a high-capacity transformer or generator feed. The TM240 ATAM trip unit delivers thermal-magnetic overload protection with an adjustable Ir range from 280 A to 400 A (the In rating), and a short-circuit pickup Ii adjustable from 5 to 10 times In.

Deployment context: where this breaker fits

The 3VA1 frame bolts into a standard distribution panel or switchboard — it's a fixed-mount MCCB, not a plug-in unit, so plan for bus-bar drilling and torque-specified terminations. The included nut keeper kit for DC Power OEM in China suggests this variant was configured for a specific OEM integration; verify the nut keeper thread and torque spec if you're replacing an existing unit in a panel built for that OEM.

Frequently asked questions

Where can I buy the 3VA1340-6EF42-0AA0-ZD00 and get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at that time.

What is the closest alternative to this breaker in the same family?

The 3VA1 family includes variants with different frame sizes, breaking capacities, and trip units. No pin-compatible direct drop-in is listed as an official successor; for a parametric match, look for another 3VA1 IEC frame 400 4-pole breaker with class H breaking capacity and a TM240 trip unit. The N-conductor protection and the nut keeper kit are specific to this order code — confirm those features on any alternative.

What compliance documentation does Siemens provide for this breaker?

The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC) for this order code. Siemens typically provides declarations of conformity and certificates on request through their support portal or your distributor.
