Kraus & Naimer CA4 A048-600 FS2 is a 10 A (Ith) CA4 series cam switch; function: ammeter selector switch with OFF (single pole, for 3 current transformers; OFF plus 3 transformer positions). Mounting: single-hole FS2 mounting (16/22 mm), 30 x 30 mm square front plate, IP66/67/69k. Switching function: positions OFF + 3 current transformer positions (4 positions); switching angle 90°; 3 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 currents of three current transformers in turn with a single ammeter.
