Low-voltage switchgear and controlgear - Part 5-1: Control circuit devices and switching elements - Electromechanical control circuit devices (Binational standard with UL 60947-5-1)
This is the harmonized CSA Group and UL standard for Low-voltage switchgear and controlgear – Part 5-1: Control circuit devices and switching elements – Electromechanical control circuit devices. It is the second edition of CSA C22.2 No. 60947-5-1 and the fourth edition of UL 60947-5-1. This edition of CSA C22.2 No. 60947-5-1 supersedes the previous edition published in 2014 as CAN/CSA-C22.2 No. 60947-5-1 (adopted IEC 60947-5-1:2003). This harmonized standard is based on IEC Publication 60947-5-1: fourth edition, Low-voltage switchgear and controlgear – Part 5-1: Control circuit devices and switching elements – Electromechanical control circuit devices, issued May 2016. IEC 60947-5-1 is copyrighted by the IEC. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Industrial Control Equipment, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This standard was reviewed by the CSA Integrated Committee on Industrial Control, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
and object This part of IEC 60947 applies to control circuit devices and switching elements intended for controlling, signalling, interlocking, etc., of switchgear and controlgear. It applies to control circuit devices having a rated voltage not exceeding 1 000 V a.c. (at a frequency not exceeding 1 000 Hz) or 600 V d.c. However, for operational voltages below 100 V a.c. or d.c., see 4.3.2.2. This standard applies to specific types of control circuit devices such as: - manual control switches, for example push-buttons, rotary switches, foot switches, etc.; - electromagnetically operated control switches, either time-delayed or instantaneous, for example contactor relays; - pilot switches, for example pressure switches, temperature sensitive switches (thermostats), programmers, etc.; - position switches, for example control switches operated by part of a machine or mechanism; - associated control circuit equipment, for example indicator lights, etc. NOTE 1 A control circuit device includes (
