Legrand Capacitor Bank in Saudi Arabia
Saudi Power Factor Company provides the Legrand capacitor bank in Saudi Arabia, supplying and installing Alpimatic automatic banks and Alpibloc fixed banks from the Alpes Technologies range. We work as an authorised Legrand partner. Both lines are factory-built units, so they suit plants that want a standard cabinet with documented ratings instead of a custom panel.

What is the difference between Legrand Alpimatic and Alpibloc?
Alpibloc is a fixed bank: capacitors connected to the supply and switched on and off as one block, normally with a single contactor or a manual breaker. It suits a base load that stays constant, such as a transformer or a large motor. Alpimatic is an automatic bank: several capacitor steps, a controller and contactors, which follow the load as it changes. Choose Alpimatic when your demand varies through the day.
Which Legrand capacitor bank in Saudi Arabia do we supply?
| Item | Range / specification | Standard | Typical lead time |
|---|---|---|---|
| Alpibloc fixed capacitor bank | 5–300 kVAr | IEC 60831 | 1–2 weeks |
| Alpimatic automatic capacitor bank | 25–1,200 kVAr, built in parallel sections at the top of the range | IEC 61921; IEC 61439-1/-2 | 2–3 weeks |
| Detuned version with reactors | 5.67%, 7% or 14% reactors | IEC 60076-6 | 3–4 weeks |
| Installation and commissioning | Cable, earth, CT connection and settings | Site inspection record | Agreed in the quotation |
Exact models depend on stock and on the ratings in your specification, so the proposal names the unit before you order.
How do I choose a Legrand capacitor bank for my plant?
Start from the bill. If the reactive demand barely changes between day and night, a fixed unit is enough. If it swings with production shifts, take the automatic unit. Check the harmonic level next: with drives or rectifiers on the bus, a detuned version prevents resonance. See the capacitor bank range for fixed units and the APFC panel page for custom assemblies.
How do I wire and troubleshoot a Legrand bank?
Wiring follows the unit drawing: three-phase supply through a protective device, a CT on the incomer phase indicated for the controller, and an earth connection. Most faults come from the CT. A reversed or mislocated CT makes the controller switch steps the wrong way. Other common causes are blown step fuses, a worn contactor and capacitors at the end of life. We test each one during a service visit and report in writing.
How does a Legrand bank project run?
- Enquiry. You send the bill or load list.
- Sizing. We calculate the kVAr and check the harmonics.
- Selection. We choose fixed or automatic, plain or detuned.
- Supply. The unit is ordered or taken from Dammam stock if available.
- Installation. We place, connect and inspect the bank.
- Commissioning. We set the target and check switching under load.
- Support. We replace worn parts, as described under retrofit.
Legrand partner questions
Who provides a Legrand capacitor bank in Saudi Arabia?
Saudi Power Factor Company provides Legrand Alpimatic and Alpibloc capacitor banks in Saudi Arabia, with delivery and installation. We are an authorised Legrand partner, active in the Kingdom since 2010. One team sizes, supplies, installs and commissions the bank.
What does a Legrand capacitor bank cost?
Cost depends on whether the bank is fixed or automatic, the kVAr rating, detuning, the enclosure and the installation work. Fixed units cost less than automatic ones of the same size. Send your bill and the proposal prices each option.
How long does a Legrand bank take?
Lead time depends on the model and stock. Our typical figures are 1–2 weeks for a fixed bank and 2–3 weeks for an automatic one, and the quotation confirms the date once the rating is fixed.
What is the difference between Alpimatic and Alpibloc?
Alpibloc is a fixed block of capacitance for a steady load, while Alpimatic has several steps and a controller that follows a changing load. The choice depends on how much your reactive demand moves.
Can you replace an old Legrand bank with a new one?
Yes. We remove the old unit, check the cabling and CT, fit the new bank in the same position where the space allows, and commission it. We also take back used capacitors for proper disposal.
Do you service banks of other makes?
Yes. We service, retrofit and supply parts for banks of other manufacturers, so a Legrand unit can be added to a plant that already holds mixed equipment, and we test the whole group together.
