IEC Load Switches. Our Bulletin 194E Load Switches are designed for use as local motor isolation and disconnect switch applications. Our switches are available in 3- and 6-pole versions with add-on additional poles, grounding and neutral terminals and auxiliary contacts. These switches share the same operating handles as the Bulletin 194L Control and Load Switches.

The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here.
