That range covers motor-starting inrush and feeder protection without nuisance tripping, but watch the Ii floor if your load has a high magnetizing peak — the 5x minimum may be too low for some transformer or large motor circuits. The integrated undervoltage release (UVR) operates on 208-230V AC 50/60Hz and drops the breaker if control voltage falls below the dropout threshold — standard for emergency-stop circuits or mains-loss protection on machine tools. ## Accessories included Comes with a nut keeper kit and two HQ auxiliary switches for remote status indication (open/closed/tripped). The auxiliary switches share the same terminal compartment as the UVR coil — verify polarity and free-wheel diode on the UVR if you're driving it from a PLC output, as the coil is inductive. No EOL or LTB notice applies.","metaTitle":"Siemens 3VA1116-4EF32-0DC0 Circuit Breaker, 160A, 36kA @ 415","metaDescription":"Siemens 3VA1116-4EF32-0DC0 IEC frame 160 circuit breaker, 3-pole, 36kA breaking capacity @ 415V AC, TM240 thermal-magnetic trip, 160A rated current.
