Where and by whom busbar holders are used
Busbar holders are widely used in low-voltage switchgear assemblies and switchboards — from main distribution boards (MDB) to load distribution panels and incoming switchgear. They are selected by LV switchgear manufacturers (serial and custom lines), panel builders, design bureaus and procurement departments. End applications include industrial facilities, commercial and office real estate, warehouses, high-rise residential buildings, and mission-critical infrastructure with high power reliability requirements, including data centers.
Typical market situation
- Mass-market catalogs from DKS, IEK — wide but generic selection without alignment to specific switchboard design
- Documentation limited to general specifications, does not meet acceptance committee requirements
METAENERGY solution
- Complete busbar holder supply in one order: profile, insulators, fasteners — tailored to specific project design
- Full product documentation package for project and acceptance: passport, compliance certificate, design documentation upon request
What is included in a standard METAENERGY busbar holder
The base is an aluminum profile with perforation (length up to 2100 mm, dimensions 40×15 mm, pitch 12.5 mm), designed for mounting in cabinets of various architectures. For currents from 2500 A and large busbar cross-sections, a reinforced version with additional profile is used.
Insulating elements are glass-fiber-reinforced polymer insulators. The glass-filled polyamide body without phenolic resins ensures stable geometry and high mechanical strength. Hardware and transitional mounting elements are included in the kit.
The model is selected according to the switchboard design documentation: busbar width and thickness, number of poles, mounting type.
Below are the serial models and available configurations that cover most project requirements.
Products
The Busbar Holders group includes ready-to-install kits and individual mounting elements. All products are manufactured per TU 27.33.13-014-97798631-2022.
METAENERGY busbar holders are available in single-pole, three-pole, and four-pole configurations. Within each type, paired and intermediate mounting options are offered for busbars with 5 mm or 10 mm thickness. Profile and insulators are supplied together, eliminating on-site assembly by the customer.
MK series
MK Busbar Holders (kits)
Modular busbar holders on aluminum profile with polymer insulators for mounting copper or aluminum busbars in low-voltage switchgear up to 1000 V. Supplied as complete kits: profile of required length, insulators, studs, nuts, insulating sleeves, and support bushings.
- Single-pole (paired mounting only), three-pole and four-pole versions
- Insulators for 5 mm or 10 mm busbar thickness; reinforced profile option for high current applications
- Profile length from 125 to 2100 mm in 12.5 mm increments; custom versions per customer drawing
When ordering, specify number of poles, mounting type (paired/intermediate), busbar thickness, and profile length. Non-standard stud length available upon request.
mounting hardware kits
Hardware for Busbar Holders
Separately supplied fasteners and kits for mounting busbar holders in enclosures: profile mounting kit and insulator mounting kit. Include bolts, nuts, washers, and insulating sleeves.
- Stand-alone items for spare parts replenishment or repair
- Compatible with all MK series busbar holder sizes
Use for cost estimation and specification at the design stage. Part numbers available in catalog.
Sizes and Selection
Precise selection is based on engineering documentation and the current METAENERGY catalog. Key dimensional parameters available in standard product range are listed below.
Base configurations of MK busbar holders
| Type | Number of poles | Busbar thickness, mm | Mounting type | Typical profile length, mm |
|---|---|---|---|---|
| Single-pole (1×1-position) | 1 | 5; 10 | paired | 50–2100 (per catalog) |
| Three-pole (3×2-position) | 3 | 5; 10 | paired / intermediate | 50–2100 (pitch 12.5) |
| Four-pole (4×4-position) | 4 | 5; 10 | paired / intermediate | 50–2100 (pitch 12.5) |
Comparison / key parameters
Comparison of METAENERGY solutions with typical market alternatives based on switchgear manufacturer and design organization requirements.
| Parameter | Mass-market catalog (DKC, IEK) | METAENERGY |
|---|---|---|
| Completeness | Items purchased separately; incomplete sets possible | Complete set 'profile + insulators + fasteners' in one delivery |
| Insulator material | Often generic 'plastic' designation | Glass-filled polyamide without phenolic resins, documented certification |
| Acceptance documentation | Basic label and general certificates | Product passport, technical specifications, design documentation on request per customer requirements |
| Project compatibility | Limited to fixed catalog configurations | Adaptation for domestic and foreign cabinets, transition elements, custom manufacturing per drawing |
| Replacement of imported brands | Direct replacement not guaranteed without verification | Possible replacement of ABB, ERICO, Legrand, Schneider, RITTAL after verification with design engineer (mounting and fitting dimensions) |
