The IEC 61439 – the new IEC standard series - is available for low-voltage switchgear and control gear assemblies. The IEC 61439 series replaces the old IEC 60439 standard series following dissatisfaction over the uses of the series which were lacking in several areas.
A typical switchgear and controlgear assembly in the substation is shown in figure 2. Fig.2 ACDB Panel in Substation. Relevant Standards for Lv S&C Assemblies. Several standards govern the design, manufacturing, testing, and application of low voltage switchgear and controlgear assemblies. The most significant standards include: IEC 61439 SeriesLow-voltage switchgear provides short-circuit and overload protection via low-voltage power circuit breakers (LV-PCB) with integral trip units. These low-voltage circuit breakers are typically through-the-door, draw-out devices. Like medium-voltage switchgear, low-voltage switchgear is also less often installed with individual panel design on site, but delivered as factory-assembled, type-tested switchgear. For design verification, testing is to be accomplished successfully in compliance with IEC 61439-1 and IEC 61439-2 . Switchgear type construction is evaluated against the following standards and guides: UL 1558 — Standard for Metal-Enclosed Low-Voltage Power Circuit Breaker Switchgear. ANSI/IEEE C37.20.1 — Standard for Metal-Enclosed .
The present technical manual is intended as an aid in project design and the application of low-voltage switchgear and controlgear in switchgear assemblies and machine control. The focus of the document is on electromechanical switchgear, however electronic devices used in low-voltage engineering have also been included.Low-voltage metal-enclosed switchgear is a three-phase power distribution product designed to safely, efficiently, and reliably supply electric power at voltages up to 1,000 volts and current up to 6,000 amps. The relevant standards such as IEC 60947-1 (low voltage switchgear) and IEC 60439-1 (Low voltage switchgear assemblies) define upper limits for the temperatures of the relevant constructive parts. IEC 60204 (Safety of machinery – Electrical equipment of machines) refers to IEC 60439-1. Low-voltage metal-enclosed switchgear is a three-phase power distribution product designed to safely, efficiently and reliably supply electric power at voltages up to 1,000 volts and current up to 6,000 amps.
