Low-Voltage Switchgear and Controlgear Part 5-5: Control Circuit Devices and Switching Elements Electrical Emergency Stop Devices with Mechanical Latching Function - Incorporates Amendment A11: 2013
 N EN 60947-5-5

Annotation

This s ection of IEC 60947-5 provides detailed specifications relating t o the electrical and mechanical construction of emergency stop devices with mechanical latching function and to their testing.

This standard is applicable to electrical c ontrol 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 (see annex A).

This European 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.
