BS EN IEC 60947-5-5:2026

This standard BS EN IEC 60947-5-5:2026 Low-voltage switchgear and controlgear is classified in these ICS categories:

• 29.120.99 Other electrical accessories
• 29.130.20 Low voltage switchgear and controlgear

IEC 60947-5-5:2026 This edition includes the following significant technical changes with respect to the previous edition: a) re-shaping the document with the clause numbers and names to be in line with other documents of the 60947 series; b) review of the test method to reasonably determine that the latch mechanism meets the requirements of the document; c) new Annex B for special requirements for illuminated push-button type emergency stop devices, including the reference to a function to distinguish between "active and inactive" by changing the colour of the push-button depending on the illumination. This part 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 document is applicable to electrical control circuit devices and switching elements which are used to initiate an emergency stop signal. Such devices can be provided with their own enclosure and will be installed according to the product documentation. This document does not apply to: – emergency stop devices for non-electrical control applications, for example hydraulic or pneumatic; – emergency stop devices without mechanical latching function. An emergency stop device conforming to this document can also be used as part of an emergency switching off means in compliance with IEC 60364-5-53. NOTE See also IEC 60204-1:2016 and IEC 60204-1:2016/AMD1:2021, 9.2.3.4. This document does not address specific requirements on acoustic noise as the noise emission of electrical emergency stop devices with mechanical latching function is not considered to be a relevant hazard. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision.
