Description

 

Low-voltage cabinets (LVC) are intended for completing the panels for receiving and distributing the electrical energy, as well as for the protection against overloads and short-circuit currents in three-phase electrical grids with dead-earthed neutral in four-wire and five-wire versions of three-phase alternating current with a frequency of 50 Hz and voltage up to 1000 V.

LVC are used in the power supply systems of agricultural facilities, oil and gas fields, residential buildings, individual settlements, industrial enterprises and substations.

Parameters

 

LVC operation conditions:

  1. LVC climatic version and placement category — Y3 in accordance with GOST 1515-69;
  2. Ambient air temperature from +5° C to +40° C;
  3. Environment is non-explosive, free of dust, including conductive dust, corrosive vapors and gases in concentrations that destroy metal and insulation;
  4. Air relative humidity up to 80% at the temperature of 20ºС;
  5. Installation altitude above sea level is no more than 2000m (when operating the panels at an altitude of more than 1000m.

 

MNS low-voltage withdrawable cabinet is ABB’s advanced low-voltage switchgear technology.

MNS is a modular, multi-functional low voltage distribution cabinet in the world more than 40 years of operating history, widely used in metallurgy, petroleum, chemical, industrial and mining enterprises, and infrastructure for all occasions that require high reliability low-voltage systems, power distribution and motor control systems.

MNS cabinet has highly flexible, can be installed in a variety of models and specifications of components according to specific needs and different occasions. Alternatively, you can depending on the various types of electrical equipment feeding unit mounted in the same column or the same cabinet as feeder circuits and motor control circuits can be mixed together.

MNS low-voltage withdrawable cabinet is a full range of low-voltage switchgear, low-voltage system is suitable for all rated current 5000A or less.

Drawers: 8E/4, 8E/2, 8E, 12E, 16E, 20E, 24E for cabinet plan and various options:

Adapter unit for side outgoing withdrawable cabinet:

8E/4 and 8E/2 Unit drawers:

Combined bus clamp

Combined bus clamp series is mainly used for MNS series rear-outgoing low-voltage switchgear (Horizontal bus in the top of cabinet) as fixing the horizontal busbar.

This modular busbar clamp is made of a metal mounting brackets, plastic insulator, magnetically shielded washers, bolts, and nuts.

Plastic insulator insert into metal mounting bracket by symmetrical

arrangement, and fixed with bolts and nuts. Installing plastic washer between metal bracket and screws to prevent from toroidal magnetic field after on power. This combined busbar clamp is assembled insulator structure with easy combination and use.

Technical parameters:

  1. Rated working voltage 660V,
  2. Rated short time withstand current 50KA (1S),
  3. Rated peak withstand current 105KA.

You can order component and spare parts catalogs for more than 25,000 low-voltage enclosure components from METTZ group.
