Kraus & Naimer KG10 T206/40 KS51V Emergency Stop Main Switch, 6-Pole, 20 A, in Enclosure (KS51V)

Kraus & Naimer KG10 T206/40 KS51V is a 20 A (Ith), 6-pole emergency stop main switch (red handle, yellow front plate); supplied as a maintenance and safety switch in a KS series plastic enclosure (KS51V), IP66/67, enclosure size 120 x 85 x 90 mm. Ratings: rated insulation voltage Ui 690 V, impulse withstand voltage Uimp 4 kV, AC-21A 20 A, three-phase motor rating at 380–440 V: AC-3 3.7 kW, AC-23A 5.5 kW, breaking capacity 120 / 120 / 80 A (220–240 / 380–440 / 660–690 V), maximum fuse 20 A gG or C16 LSS (400 V, 16 A), short-time withstand current 130 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. The enclosure has IP66/67 protection and is flame resistant to UL94 V-0; a ground terminal and a safety interlocked cover are standard equipment. The cover interlock only allows the cover to be opened at the 9 o'clock position. It includes 1 NO + 1 NC auxiliary contacts; the auxiliary contacts close after the main contacts close and open before the main contacts open. The KG and C316 series switches exceed the requirements of IEC 60947-3 / EN 60947-3 (VDE 0660 part 107), IEC/EN 60204 and VDE 0113 and are used as switch disconnectors, main switches and maintenance switches.
