LE2191 Rotary Limit Switch is the yaw system for protection of electrical installations twisted cables. When the wind turbine in one direction to achieve the alarm continued to yaw to set value, said the cable has been twisted to a dangerous level, Rotary Limit Switch action, causing the safety stop, and untie the rope. 1.Performance profileLE2191 Rotary Limit Switch stainless steel spindle and high strength thermoplastic material, high precision and it wears resistance.Switch to the speed ratio of 1 : 100 , and the supporting external gear drive to meet an arbitrary unit yaw protection needs. Speed ratio a variety of delivery tray can be customized according to Customer' needs. 2.Technical standards Technical specifications The scope of application instructions 73/23/CEE 93/68/CEE Conformity to Standards EN 60204-1 EN60947-1 EN60947-5-1 EN60529 EN50013 IEC536 Ambient temperature Storage -40/+70 Operational -25/+70 protection degree IP 65 Insulation category Grade II Cable Entry Cone-beam clampM20×1.5 Technical Specifications of the Switches Utilisation category AC 15 Rated operational current 3 A Rated operational voltage 250 V rated thermal current 10 A rated insulation voltage 300 V mechanical life 1×106 . operations Terminal referencing According to EN 50013 Connections coupling screwing
