It uses screw terminals for the control circuit connection. The 0.8 to 1.1 tolerance (320 V to 440 V) means the coil will pick up and hold across a typical AC line sag, but a sustained drop below 320 V risks dropout — important for brownout-prone sites. The screw terminal connection matches standard panel wiring practice; no special tooling needed.","metaTitle":"Siemens 3RT1934-5AV01 SIRIUS Magnet Coil, 400 V AC 50 Hz","metaDescription":"Siemens SIRIUS 3RT1934-5AV01 magnet coil for Size S2 contactors, 400 V AC 50 Hz, screw terminal.
