This is the part for protecting a motor branch circuit where you need electronic overload accuracy and a wide ampacity window — common on large pumps, compressors, or conveyor drives in a 400/690 V distribution panel. The 160-320 A adjustable L-range means this single breaker covers a 2:1 motor FLA spread — you can set it to match the motor nameplate without swapping the breaker body. That matters when your BOM covers multiple motor sizes in the same frame. The Class 30 electronic trigger allows a longer thermal memory than a standard Class 10 or 20, so it won't nuisance-trip on high-inertia starts (centrifuges, large fans) that draw sustained inrush for 20-30 seconds. The 13 x I_in instantaneous magnetic trip (320 A x 13 = 4160 A) clears hard short-circuits fast enough to coordinate with a downstream contactor. ## Panel integration Mounts on standard DIN rail in the motor control center or distribution panel. The electronic trigger module is field-adjustable via the front dial; no need to open the arc chamber to change the L-setting. Auxiliary contacts and shunt trip accessories from the 3VU2 family snap on the side without additional wiring space.","metaTitle":"Siemens 3VU2042-0FL60 Motor Protection Circuit Breaker, 160-","metaDescription":"Siemens 3VU2042-0FL60 motor protection circuit breaker, Class 30 electronic trigger, 160-320 A adjustable, 690 V.
