SENTRON 3VA1116-3GF42-0AA0 — 160 A, 4-Pole MCCB with TM240 Release
This is a common setup for feeders where the cable or bus rating caps the load at 160 A while the breaker's magnetic trip remains sized for the higher short-circuit withstand.
Short-circuit breaking capacity varies with system voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V AC. The 690 V rating is the rated operating voltage, so this breaker can serve 480 V or 600 V class panels with ample SCCR headroom; the 11.9 kA at 690 V is the limiting case for high-voltage industrial grids.
Rated current holds at 160 A from 40 °C through 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C.
