Introduction

The enclosed isolating switch referred to in this standard is intended for a variety of purposes, mainly in the repair and cleaning of electrical circuits (especially motor circuits) and Maintenance work to provide electrical equipment isolation. This enclosed disconnector is also referred to as a "service switch" or a "safety switch." "Safety switch" is also used for safety-related positions Off, test switch and other switches not covered in this standard. This standard specifies, in accordance with IEC 60947-3, a closed isolating switch that provides isolation in the maintenance and servicing of electrical equipment Additional requirements. The enclosed isolating switch provided by this standard is generally installed near the isolated electrical appliance and operated by professionals. NOTE Disconnectors do not have to meet the requirements to prevent unintended start-up, especially if there are other sources of energy other than electrical energy. Low-voltage switchgear and control equipment Part 1. Provided for repair and maintenance work Isolated isolation switch function

1 Scope

This standard applies to AC rated voltage does not exceed 1000V, in the load circuit for maintenance, maintenance and cleaning of the enclosed compartment Off the switch. These enclosed disconnectors are derived from the disconnectors in IEC 60947-3 for use in the IEC 60947 series To prevent unintended start-up from occurring, it is not recommended to install remote control or automatic switch. This type of appliance is not intended for use in the circuit Off, fast start and stop or jog load. Note 1. This type of appliance may disconnect the electrical equipment (whether or not it is in normal operation). The enclosed isolating switch in this standard provides electrical equipment (especially in motor circuits) for repair and maintenance work or cleaning work. Isolated. An enclosed disconnector that isolates electrical equipment during repair and maintenance work is also referred to as a "service switch" and provides the following content. a) different grades, see chapter 4; b) the characteristics of each level; c) the minimum test requirements; d) Information that should be indicated on the appliance, or information provided by the manufacturer, such as product samples. Note 2. This standard does not specify the necessary additional requirements for the application of these switches, such as in explosive atmospheres (eg the European ATEX Directive).
