6 1Technical data on request. 2Additional length for switches with B, C, S, amendments refer page 54. How to order Disconnectors and Main Switches according to IEC 60947-3 see Catalog 500 Three types of data (shown below) are required for ordering Blue Line cam-operated switches. Code numbers for ordering are shown in this catalog. 1. Type of Switch The type of switch required may be easily selected by referring to the table on page 5 which shows the thermal current, power rating and dimensions of each switch. For further technical details, refer to pages 44-47. Variations of contacts and terminals are shown below. 2. Switch Function The code numbers for standard switches shown on pages 8-32 indicate the switch function, face plate, handle and any optional extras. Additional coding to modify type and color of handle and face plate is explained below. 3. Type of Mounting Types of mounting are shown on pages 33-39. Catalog 101 describes enclosures and optional extras. Specify the mounting code to indicate required mounting. CA10 A202 VE Handles, Face Plates and Optional Extras The handles for standard switches shown on pages 8-32 are suitable for mounting units with four hole mounting. Alternative types of handles available are illustrated on page 42, and mounting units on pages 31-37. When a handle, face plate or optional extra is required but not covered by the dash number, the code number for the selected component should be entered separately. A comprehensive range of available standard face plates is illustrated on pages 40 and 41. Non-standard or special face plate engravings are available at extra cost. The large number of optional extras and enclosures is covered in Catalog 101. Switch Size Blue Line switches are available in sizes S00, S0, S1, S2 and S3. These size codes indicate the dimensions of the mounting, the face plate and the handle, as well as the size of optional devices and enclosures. Page 5 lists these sizes and the various switch types they include. Type of Switch Extending the switch type coding the following combinations will define: Amendment Definition For switch types -1 with gold contacts1 CA4-1, CA4N-1, CA10-1, CA11-1, CA10B-1, CA11B-1, CAD4-1 -4 with quick connects CA4-4 B2 S0 switches with latching mechanism size S1 CA10B, CA11B, CA25B, CAD11B, CAD12B C2 S1 switches with latching mechanism size S2 CA40C, CA50C, CA63C L with lockout-relay w/o manual release for std. sw.
