Product details

The Siemens 3VA1050-4ED42-0AA0-ZD00 is a 4-pole IEC frame 100 circuit breaker with a 50 A fixed thermal-magnetic trip (TM210, FTFM) and a breaking capacity of 36 kA at 415 V AC — class S in the 3VA1 line. The fixed Ir=50 A and Ii=10 x In (500 A short-circuit pickup) suit it for dedicated feeder or branch protection where no field-adjustable overload is needed.

Deployment context

This breaker mounts on a DIN rail inside an IEC enclosure — the 3VA1 frame footprint is standard for panel integration. The nut keeper kit for DC Power OEM in China indicates it ships with hardware for captive nut retention, which simplifies assembly in OEM builds where the breaker is installed into a pre-punched gland plate.

Frequently asked questions

Where can I buy the 3VA1050-4ED42-0AA0-ZD00?

This part is sourced and quoted to order against an RFQ through independent distribution, with availability and current pricing confirmed at quote time.

What is the breaking capacity of this circuit breaker?

The rated ultimate short-circuit breaking capacity (Icu) is 36 kA at 415 V AC, which is the class S rating for the 3VA1 IEC frame 100 series.
