Line protection breaker with 160 A continuous rating
At 160 A the breaker is sized for main feeder or large motor branch protection in 400 V class distribution. The thermal derating curve stays flat at 160 A from 40 °C through 50 °C, then drops to 153.6 A at 55 °C and 144 A at 70 °C.
Selectivity and coordination in a distribution panel
Mounts on a standard DIN rail or direct-panel footprint — the 76.2 mm width (3-pole) and 130 mm height fit alongside other SENTRON 3VA frame sizes in a common busbar arrangement. The UVR (undervoltage release) drops the breaker on loss of control voltage, which is typical for emergency-stop or undervoltage protection schemes. If the control circuit doesn't require that, the 3VA1116-5EF32-0BH0 has it built in — no separate module to buy, but it does add a wiring point for the release coil. It's a pure thermal-magnetic breaker with auxiliary status reporting via the 2 aux switches and the trip alarm switch. For a panel that needs remote trip indication, those contacts are already there.
