Kraus & Naimer CG8 A007 is a 20 A (Ith) CG8 series cam switch; function: voltmeter selector switch with OFF for 3-phase 3-wire systems (3 phase-to-phase, OFF and 3 phase-to-neutral positions, 7 positions in total). Front plate 48 x 48 mm. Switching function: positions 3 phase-to-phase + OFF + 3 phase-to-neutral (7 positions); switching angle 45°; 3 contact stages. Ratings: rated insulation voltage Ui 690 V, impulse withstand voltage Uimp 6 kV (switch), AC-21A 20 A, maximum fuse 25 A gG, short-time withstand current 140 A (1 s). Connection: flexible conductors 0.75–2.5 mm², solid or stranded conductors 0.5–2.5 mm², terminal tightening torque 0.6 Nm. It is used to select and read phase-to-phase and phase-to-neutral voltages with a single voltmeter.
