家用及其他类似用途机电接触器

[中文适用范围]： This document applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V AC (between phases) with rated operational currents less than or equal to 63 A for utilization category AC-7a, and 32 A for utilization categories AC-7b, AC-7c and AC-7d (expressed in rated power), and rated conditional short-circuit current less than or equal to 6 kA. The contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 9.3.4) shall form part of the installation. NOTE Today, most LED lamp manufacturers provide information in Watt. So, the main contactor characteristic for utilization category AC-7d is expressed in Watt to be directly applicable to the corresponding LED lamp load. Specific requirements apply to contactors equipped with screwless-type terminals. This document does not apply to - contactors complying with IEC 60947-4-1; - semiconductor contactors; - contactors designed for special applications; - auxiliary contacts of contactors. These are dealt with in IEC 60947-5-1. This document states 1) the characteristics of contactors. 2) the conditions with which contactors-shail comply with reference to: a) their operation and behaviour; b) their dielectric properties; c) the degrees of protection provided by their enclosures, where applicable; d) their construction; e) their electromagnetic compatibility characteristics. 3) the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests. 4) the test sequences and the number of samples. 5) the information to be given with contactors or in the manufacturer's literature. [外文原描述]： IEC 61095:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61095:2023 applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V AC (between phases) with rated operational currents less than or equal to 63 A for utilization category AC-7a, and 32 A for utilization categories AC‑7b, AC‑7c and AC-7d (expressed in rated power), and rated conditional short-circuit current less than or equal to 6 kA. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of requirements for screwless terminals; b) addition of requirements for the switching of LED lamps. Contactors for domestic and similar applications can be used for controlling lighting loads which is increasingly using LED lamp technology. A specific category for contactors is created: AC-7d. Requirements and tests are added to cover this market development, mainly for making and breaking and conventional operational performance; c) addition of requirements for contactors with electronically controlled electromagnet. Household contactors with electronically controlled electromagnet are available for years on the market. To fully cover such device, requirements and tests are added, dealing mainly with operating limits, behaviour in abnormal conditions, breakdown of components, EMC tests, etc. d) embedded software. More and more contactors are incorporating electronic circuits with embedded software. A reference is provided to guide the design of the software.
