Product details

At 415 V the interrupting rating is 75.6 kA, and at 690 V it holds at 11.9 kA, so the same breaker can serve a 400 V bus with plenty of fault-current margin. The 50 A rating holds flat from 40 °C up to 50 °C; above that it derates gradually to 45 A at 70 °C. It's a straight line-protection breaker for a fixed load. The 100% N-conductor protection means the neutral pole is rated the same as the phase poles, so it's suited for 4-wire systems where the neutral carries full phase current.

Front-face IP40 protection keeps dust and tools out of the mechanism in a clean indoor panel.

Frequently asked questions

Where can I buy the 3VA1150-4GD46-0AA0 and how is it quoted?

This breaker is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability — no stock count or price is listed publicly.

What is the breaking capacity of the 3VA1150-4GD46-0AA0 at 240 V?

121 kA at 240 V, which is the highest interrupting rating for this breaker across all voltage levels.

Does the 3VA1150-4GD46-0AA0 have a trip indicator or communication module?

No trip indicator on the front, and no communication function is fitted. It's a basic line-protection MCCB with a fixed TM210 release.

What is the operating temperature range for this MCCB?

Rated for -25 °C to +70 °C operating ambient, with storage from -40 °C to +80 °C. The 50 A rating holds up to 50 °C ambient; above that it derates to 45 A at 70 °C.
