Optional Extras For Switch Sizes S0 S1 S2 S3 V350/A V350/B V350/C V350/D Operating voltage and frequency: AC/50 Hz AC/60 Hz AC/50/60 Hz DC The device includes a magnetic system which releases the switch to the trip position at voltage failure or undervoltage of 70 % of the nominal voltage. The device is trip-free, in that the switch can be operated only when the primary voltage is available. When using DC voltage, an economy resistor must be provided. Switches with integrated undervoltage release are described on page 23. Electromechanical Trip Device (Undervoltage Release)1 Ordering data: Operating voltage and frequency for the magnetic system. V360/A The device permits the switch to be turned to the trip position by remote control. The coil is designed for shorttime duty requiring an auxiliary contact in the switch which de-energizes the coil in the trip position. On activation, the handle will switch to TRIP position. After a trip has occurred, the handle has to be turned to the OFF position thereby loading the return spring. Manual turning to TRIP position is not possible in the normal operation. Controlling of the magnetic system: 24 V-440 V/50 Hz, 60 Hz or DC Electromechanical Trip Device (Shunt-trip)1 Ordering data: Operating voltage for the magnetic system. R300 The motor drive consists of an AC motor with capacitor, gear train and Geneva gear. This device allows switches to be operated from a remote location. Motor voltages available are 230 V, 50 Hz and 117 V, 60 Hz. Possible control systems: - Follow-up control - Impulse control Further information as well as special control systems upon request.
