Product details

The Siemens 3VA1050-4ED32-0AF0 is a 3-pole IEC frame 100 circuit breaker from the 3VA1 series, rated at 50 A with a fixed thermal-magnetic overload release (TM210) and a fixed short-circuit protection setting of 10 x In.

Integration Notes

The nut keeper kit secures the breaker during high-vibration environments like conveyor or pump panels. The auxiliary switch HQ and trip alarm switch HQ provide remote status feedback — the HQ auxiliary signals the breaker's open/closed position, while the trip alarm signals a fault trip, useful for PLC-based alarm annunciation or motor control center (MCC) status monitoring.

Frequently asked questions

What is the breaking capacity of 3VA1050-4ED32-0AF0?

The breaking capacity class S provides 36 kA at 415 V, which is the maximum fault current the breaker can safely interrupt at that voltage level.

What does the TM210 overload release mean on this breaker?

TM210 is a fixed thermal-magnetic release: the thermal overload is fixed at 50 A (In), and the short-circuit magnetic pickup is fixed at 10 x In (500 A). No adjustment dials — set it and forget it for a dedicated load.

Where can I buy 3VA1050-4ED32-0AF0 and get current pricing?

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