SENTRON 3VA1050-2ED32-0CA0 — 50 A MCCB with TM210 Trip Unit
Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. The 690 V rating of 7.5 kA is relevant for 690 V drives or mining applications where fault levels are lower.
The 76.2 mm width is a standard 3-pole MCCB footprint that fits a 4-module (4 x 18 mm) DIN-rail space. The 70 mm depth keeps the breaker within typical 200 mm enclosure depths, leaving room for wiring gutters and busbar connections behind the panel door. No auxiliary contact or communication module is fitted as standard; the UVR is the only integrated release.
Derating begins at 55 °C (48 A), dropping to 45 A at 70 °C. For a panel with internal temperature rise, this means the breaker can be loaded to nameplate at 50 °C without margin — a common condition in sealed enclosures with multiple devices.
