Neutral bars keep electrical circuits stable. They connect the neutral and ground wires safely inside the panel. Used in control panels, switchgear, and distribution boxes.
We make three main types. Brass neutral bar for strong threads and corrosion resistance. Aluminum neutral bar for lightweight systems. Copper neutral bar for high current capacity.
Each bar is machined clean, drilled straight, and tested before dispatch. Also available as neutral links and ground bars for standard and custom panels. Supplied across Spain and Europe.

Neutral bars come in several material grades and dimensions. Each bar is cut, drilled, and finished to match control panel standards. Every unit passes thread and flatness inspection before packing.
| Specification Type | Details |
|---|---|
| Material Options | Brass – corrosion resistant and durable. Copper – high conductivity for heavy load. Aluminum – light weight, cost-efficient. |
| Typical Cross Sections | Custom Size as per requirements and drawing |
| Thread Sizes | M4, M5, M6, M8 (other sizes on request) |
| Surface Finish | Natural, nickel plated, or tin plated |
| Inspection Parameters | Flatness, hole alignment, thread gauge, surface finish |
| Mounting Options | Insulated bases, brackets, or direct panel fit |
Each barra colectora neutra de latón or enlace neutro is checked for proper spacing and thread quality. Ground bar versions can include mounting insulators for added safety.
The choice of material defines current capacity, durability, and long-term stability. Each barra neutra type serves a specific purpose in electrical distribution and control systems.
| 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 |
| Finish Type | Natural, nickel plated, tin plated |
| 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.
| Application Type | Recommended Material | Typical Current Range | Standard Reference |
|---|---|---|---|
| Control Panel | Brass | Up to 125 A | IEC 60947-7-1 |
| Distribution Board | Copper | 125–250 A | IEC 61439 |
| Switchgear | Copper | 250–600 A | IEC 61439-2 |
| HVAC / Power Cabinet | Aluminum | Up to 150 A | EN 60204-1 |
| Grounding Bar | Brass or Copper | As per system design | IEC 60364 |
