Catalog excerpts

Rotary cam switches series CS are intended for multiple switching operations in main as well as in auxiliary circuits: ■ As motor switches they are designed for direct-online starting and stopping of single- phase and three-phase motors. They also come out as star-delta switches, reversing switches, pole-change over motor switches. ■ In auxiliary circuits they are assembled in compliance with the switching programme according to preference: • switches for control, signalling and measuring circuits. • switches, selector switches and step switches e.g. for transformers and welding apparatuses. • Group switches e.g. for switching operations of resistors and heaters. • Control switch with automatic return Advantages ■ high making and breaking capacities ■ electrical and mechanical endurance ■ small dimensions. Rotary cam switches comply with international and national standards such as: IEC/EN 60947-3, VDE 0660,TS EN 60947-3, BS 5419 etc. Designation CS XX(Ith[A]) YY(diagram) Z_(design) Connection diagram in technical data 392 Technical data on page 423
