First paragraph

Replacement:

This standard applies to electro-magnetic air-break contactors in accordance with IEC Publication 158-1 for which additional requirements are necessary in order to specify in sufficient detail certain testing parameters and procedures.

Additional notes:

  1. — The need for additional requirements appears, for example, when contactors have to be tested and certified by appropriate testing authorities because of national or other laws or rules.

  2. — If control switches are incorporated in contactors they shall comply with I EC Publication 337-1: Control Switches (Low-voltage Switching Devices for Control and Auxiliary Circuits, Including Contactor Relays), Part 1: General Requirements.
