This breaker carries 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V.
Rated 50 A from 40 °C through 50 °C, then it starts to taper: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C. The 14.6 W maximum power loss also needs to be factored into the enclosure thermal budget, especially in a sealed cabinet.
The closest functional peer within the SENTRON 3VA family is the 3VA1110-5ED36-0AC0. Both are 3-pole line-protection MCCBs, but the 3VA1110-5ED36-0AC0 uses a different trip unit and has a lower current rating — verify your load and coordination requirements before substituting.
Yes, the 70 mm depth and 76.2 mm width are shared across the 3VA platform, so the mounting footprint and bus-bar spacing are identical. The line and load connections are in the same positions — no backplate modification or re-drilling needed.
