Product details

The Siemens 3VA1150-5GD42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker from the 3VA1 series, rated In=50A with a fixed overload protection Ir=50A and fixed short-circuit protection set at Ii=10 x In.

Deployment context

This breaker includes a nut keeper kit for DC Power OEM applications in China, so it's pre-configured for panel integration where the neutral conductor is protected at 100% and the line protection uses a TM210 thermal-magnetic trip unit with FTFM (fixed thermal, fixed magnetic) settings. The 4-pole format suits three-phase plus neutral distribution in switchboards or motor control centers.

Frequently asked questions

What is the breaking capacity of this breaker?

The breaking capacity class M gives Icu=55kA at 415V, which is the maximum short-circuit current the breaker can safely interrupt at that voltage.

What is the overload and short-circuit protection setting?

Overload protection Ir is fixed at 50A; short-circuit protection Ii is fixed at 10 x In (500A). Both are thermal-magnetic, non-adjustable.

Where can I buy 3VA1150-5GD42-0AA0-ZD00?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
