Product details

What this breaker delivers

The Siemens 3VA1050-3ED42-0CA0 is a 4-pole IEC frame 100 molded-case circuit breaker with a 50 A fixed thermal-magnetic trip (TM210) and a 25 kA interrupting capacity at 415 V AC (class N).

The fixed Ir=50 A overload setting and fixed Ii=10 x In short-circuit pickup (500 A magnetic) mean no adjustment dials — set-and-forget for a dedicated feeder or motor branch. The nut keeper kit retains the terminal hardware under vibration, which matters on a weld line or conveyor drive panel.

Frequently asked questions

Where can I buy 3VA1050-3ED42-0CA0 and 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 for a firm price and lead time.

What is the interrupting rating of this breaker?

The 3VA1050-3ED42-0CA0 has a breaking capacity class N with Icu = 25 kA at 415 V AC, 4-pole. That is the maximum fault current it can interrupt without damage.

Does this breaker include an undervoltage release?

Yes, it includes an undervoltage release (UVR) rated for 120–127 V AC, 50/60 Hz. The UVR trips the breaker if control voltage drops below the dropout threshold.
