Neutral bars provide a common termination point for neutral and grounding conductors inside electrical panels. Every neutral bar we supply to Spain is precision-machined, drilled to specification, and tested for thread quality and flatness before dispatch.
We manufacture and export three main types: brass neutral bar for strong threads and corrosion resistance in outdoor control panels, copper neutral bar for high-current switchgear and distribution boards, and aluminum neutral bar for lightweight, cost-efficient light-weight applications.
Custom hole layouts, bar lengths from 2 hole to 100 hole, and surface finishes including tin plating and nickel plating are produced to drawing or sample.
We supply OEM manufacturers, electrical panel builders, and bulk buyers across Spain and the EU. CE and RoHS certified. ISO 9001:2015 quality system. Shipment by air and sea depending on order size and urgency.
Each neutral bar supplied to Spain is produced from verified raw material stock, machined to customer specifications, and inspected before packing. The table below covers standard options, all dimensions and configurations can be customized according to drawing.

Each neutral bar (barra neutra) is inspected for hole spacing, thread depth, surface finish, and flatness before dispatch. neutral link versions are available with insulated mounting bases for IEC-compliant panel installations.
The gallery below shows recent production batches of brass, copper, and aluminum neutral bars manufactured for OEM customers.
Solid copper neutral bar manufactured with accurately drilled through holes and clean machined edges. The image reflects multiple bar lengths produced within the same batch, showing customization for different circuit counts and layouts used in electrical control panels and distribution board assemblies..
Extended-length brass neutral bar produced from solid brass stock with a visible machined surface. The bar is manufactured with 24 inline threaded terminal positions and four separate mounting holes to support stable installation. A stepped section is present at the center of the bar. This configuration is used in electrical control panels, distribution boards, and OEM assemblies where a larger number of neutral connections are required.
Machined brass neutral bar featuring 15 inline M3 threaded terminal points for conductor termination. The bar is supplied assembled with MS combination head screws and includes two side holes of different sizes for mounting. The brass body is evenly machined and intended for use in electrical control panels.
Custom Brass neutral bar produced with a tin-plated surface and machined to include 15 inline M4 threaded terminal holes. The bar shows a consistent matte tin finish with accurately machined faces and even terminal spacing. Two larger side holes are incorporated for mounting. This configuration is used in electrical distribution boards and control panel assemblies where a tin-coated brass conductor is specified.
Aluminum neutral bar has an overall length of approximately 95 mm and a height of about 12.5 mm, with 12 machined holes in total, including three dedicated mounting locations. The bar is supplied assembled with blue-coated clamping screws and is used for conductor termination in electrical distribution boards and industrial control panel assemblies.
Aluminum neutral bar manufactured for electrical distribution applications. The bar is 12 threaded circuit terminals with 10.05 mm center spacing. Two threaded mounting holes are provided for installation. Designed to accept 2–14 CU conductors, the bar is supplied assembled with combination head screws and is used in panelboards and industrial control cabinet assemblies.
The choice of material directly affects current capacity, heat tolerance, and long-term reliability. Each neutral bar supplied to Spain is according to customer drawing and requirements.
| Material Type | Key Properties | Typical Use |
|---|---|---|
| Brass Neutral Bar | Medium conductivity, strong threads, excellent corrosion resistance. | Standard electrical panels, terminals with frequent assembly. |
| Copper Neutral Bar | Highest conductivity, stable under high current, minimal heat rise. | Heavy-duty switchgear, high-power circuits, industrial bus systems. |
| Aluminum Neutral Bar | Lightweight, economical, good performance when space & cost is critical. | Large control boards, HVAC units, power distribution cabinets. |
| Tinned Finish Option | Added corrosion protection, stable resistance over time. | Outdoor & high-humidity installations. |
All materials are verified for conductivity and mechanical integrity before dispatch. Testing includes visual inspection, resistance measurement, and surface finish check.
Each neutral bar is produced under controlled machining standards. Precision starts from raw material selection and continues through every process.
CNC drilling ensures clean holes and consistent spacing. Threads are cut using calibrated taps to maintain fit accuracy. Tolerances are verified with gauges before plating.
We supply OEM and custom designs based on technical drawings or samples. Hole layout, bar length, and mounting type can be adjusted as required. Nickel and tin plating is available for corrosion protection and smooth electrical contact.
Sample pieces are usually prepared for first-off approval before bulk production. Production batches are serialized for traceability and inspection records.
| Custom Option | Specification Range |
|---|---|
| Hole Diameter | M4 to M8, or per drawing |
| Bar Length | 50 mm to 1000 mm |
| Mounting Type | Bracket, insulated base, or plain |

| Tolerance Check | ±0.05 mm hole spacing, ±0.02 mm thread pitch |
All manufacturing follows ISO inspection standards. Each bar leaves the factory verified for thread depth, spacing, and surface finish.
Neutral bars provide a common connection point for neutral and grounding conductors. They keep electrical systems safe and balanced. Each material type is selected according to current load, panel design, and operating environment.
Used as the main neutral termination point in power and automation panels. Ensures safe return paths for circuits and stable voltage balance.
Mounted inside distribution enclosures to connect multiple neutral wires. Brass and copper types handle higher current capacity, keeping temperature rise within IEC 61439 limits.
Copper neutral bar preferred in switchgear due to its high fault-current tolerance and low resistance. Helps maintain circuit protection coordination under heavy loads.
Aluminum neutral bar often used in HVAC and large power cabinets. Lower weight supports compact design and easier mounting without sacrificing conductivity.
Neutral link and ground bar work together to connect the neutral line with the earth bus, improving fault safety. Complies with grounding standards used in European electrical installations.
All materials and finishes comply with RoHS and CE marking requirements for export to Spain and the EU.
