Low Voltage Switchgears type ZMR
ZMR switchgears are used in places of production, distribution or incoming of electric energy and they work booth as a switchgears and control panels. These switchgears guarantee high level of safety and comfortable maintenance. ZMR switchgears may be equipped with switching, protecting, control, metering and signaling equipment. Modular construction with fixed or withdrawable parts enables designing of switchgear on individual clients wish. Basic frame of cubicle is made from wall-thick sections of ANKO type. Inside cubicle are three compartments: – apparatus compartment with equipment for each operating part, – busbar compartment with main busbar and with busbars of each cubicle – Cable/busbar compartment: with terminations and cables for each cubicle ZMR distribution system is designated for cubicles:

  • with fixed parts
  • with moveable parts, contactors
  • with witdrawable parts

Advantages: ZMR distribution system is modular, open and flexible. Enables free configuration of switchgear and each cubicle considering operating conditions and requirements. Comparing to traditional solutions, ZMR system has many advantages:

  • simple construction which reduce dimensions of all equipment
  • possibility of using different operating parts in one cubicle
  • possibility of using fixed, movable and withdrawable parts
  • using circuit breakers as moveable parts
  • construction which enable modernization and extension of switchgear
  • safe and easy operating and maintenance
  • high quality of corrosion protection
  • aesthetical shape

Low Voltage Switchgears type SXR0
SXR0 switchgears are designated for power supply and control of electrical energy users, specially for automated production. They can be installed both in electrical rooms and in rooms with public access. Switchgears have steel self-supporting construction. They are produced in one-side version with front access and in two-sided version with front and back doors. Cubicles can be optionally joined in units; typical unit consists of power supply-outgoing cubicle and a few outgoing cubicles. Power supply cubicle are equipped with main connector, metering of current and voltage. Incoming cubicles are placed on fixed, revolving or inclined racks equipped according to Clients wish.
