Preface: This is the first edition of CSA C22.2 No. 60947-5-5, Low-voltage switchgear and controlgear — Part 5-5: Control circuit devices and switching elements — Electrical emergency stop device with mechanical latching function, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60947-5-5 (edition 1:1997 consolidated with Amendment 1:2005 and Amendment 2:2016). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. This Standard is intended to be used in conjunction with CSA C22.2 No. 60947-1, Low-voltage switchgear and controlgear — Part 1: General rules, and CSA C22.2 No. 60947-5-1, Low-voltage switchgear and controlgear — Part 5-1: Control circuit devices and switching elements — Electromechanical control circuit devices. 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. Scope: This section of IEC 60947-5 provides detailed specifications relating to the electrical and mechanical construction of emergency stop devices with mechanical latching function and to their testing. This standard is applicable to electrical control circuit devices and switching elements which are used to initiate an emergency stop signal. Such devices may be either provided with their own enclosure, or installed according to the manufacturer's instructions. This standard does not apply to: emergency stop devices for non-electrical control circuit, for example hydraulic, pneumatic, emergency stop devices without mechanical latching function. An emergency stop device may also be used to provide an emergency switching off function. This standard does not deal with any specific requirements on noise as the noise emission of electrical emergency stop devices with mechanical latching function is not considered to be a relevant hazard. NOTE See also 9.2.5.4 of IEC 60204-1:2005.
