Kraus & Naimer CA4 A004-600 FS2 Voltmeter Selector Switch, 10 A, 30 x 30 mm Front Plate

Kraus & Naimer CA4 A004-600 FS2 is a 10 A (Ith) CA4 series cam switch; function: voltmeter selector switch with OFF for 3-phase 3-wire systems (OFF plus 3 phase-to-phase positions, 4 positions in total). Mounting: single-hole FS2 mounting (16/22 mm), 30 x 30 mm square front plate, IP66/67/69k. Switching function: positions OFF + 3 phase-to-phase (4 positions); switching angle 45°; 2 contact stages. Ratings: rated insulation voltage Ui 440 V, impulse withstand voltage Uimp 4 kV, AC-21A 10 A, maximum fuse 10 A gG, short-time withstand current 60 A (1 s). Connection: flexible conductors 0.75–1.5 mm², solid or stranded conductors 0.5–1.5 mm², terminal tightening torque 0.4 Nm. It is used to read the three phase-to-phase voltages in turn with a single voltmeter.
