IEC Standards

This part of IEC 61000 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and the required test procedures.The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to radiated,radio-frequency electromagnetic fields. The […]

This part of IEC 61 000 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which can be produced by equipment tested under specified conditions.

This document applies to control and protective switching devices (or equipment) (CPS), the main contacts of which are intended to be connected to circuits of rated voltage not exceeding 1 000 V AC or 1 500 V DC. It covers control and protective switching device (CPS): – which provides protective and control functions for circuits

This part of IEC 60947 series specifies requirements for three-position enabling switches. These switches are used as components of enabling devices to provide signals that, a) when activated, allow machine operation to be initiated by a separate start control, and b) when de-activated,

This document applies to semiconductor controllers and semiconductor contactors for non-motor load intended to be connected to circuits, the rated voltage of which does not exceed 1000VAC.

This part of IEC 60947 applies to semiconductor motor controllers, starters and sft-starters which can include a series mechanical switching device, intended to be connected to circuits the rated voltage of which does not exceed 1 000 V AC. This document characterizes semiconductor motor controllers and starters with and without bypass means.
