Kraus & Naimer KG125 T206/91 STM is a 125 A (Ith), 6-pole emergency stop main switch (red handle, yellow front plate); supplied as a maintenance and safety switch in a STM plastic enclosure with conduit entries, IP65, enclosure size 400 x 300 x 172 mm (oversized wiring space). Ratings: rated insulation voltage Ui 1000 V, impulse withstand voltage Uimp 8 kV, AC-21A 125 A, three-phase motor rating at 380–440 V: AC-3 37 kW, AC-23A 45 kW, breaking capacity 800 / 750 / 340 A (220–240 / 380–440 / 660–690 V), maximum fuse 125 A gG, short-time withstand current 2500 A (1 s). Connection: flexible conductors 16–70 mm², solid or stranded conductors 6–95 mm², terminal tightening torque 14 Nm. The enclosure has IP65 protection; a ground terminal and a safety interlocked cover are standard equipment. Codes ending in STM are supplied with conduit entries. 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.
