Automatic transfer switch panels
Automatic transfer switch panels that start your generator and take over the load within seconds of a power cut — configured to your generator, earthing system and utility requirements in Sharjah, Dubai, Abu Dhabi, Saudi Arabia and Iraq.
An automatic transfer switch monitors mains voltage and frequency. When supply fails it signals the generator to start, waits for stable output, transfers the load, and returns it to mains once the grid is healthy — then lets the engine cool down before stopping. No one needs to be on site.
We select the switching technology to suit the rating and duty:
Size the ATS to the generator's full-load current, or the incoming mains breaker if larger. At 400 V three-phase, current ≈ kVA × 1.44: a 250 kVA generator needs a 400 A ATS, a 500 kVA set an 800 A panel. Our kVA calculator recommends the ATS rating automatically.
Powder-coated IP54 enclosures (IP65 for outdoor), mechanical and electrical interlocks, clear labelling and function testing before dispatch. Panels can be configured to DEWA, SEWA, ADDC/TAQA or SEC requirements on request.
1-year warranty
Wall- or floor-mounted ATS panels that switch your load from mains to generator in seconds when power fails — and back again when it returns. Motorised changeover or contactor based, 3- or 4-pole.
1-year warranty
Floor-standing ATS and ACB-based changeover panels for industrial plants, hospitals and towers — with metering, bypass and multi-source (mains/generator/generator) logic.

FAQ
Match the ATS current rating to the generator's full-load current (or the incoming mains breaker, whichever is higher). At 400 V three-phase, current ≈ kVA × 1.44 — so a 250 kVA generator needs about 360 A, meaning a 400 A ATS.
4-pole (switched neutral) is recommended when the generator neutral is separately earthed or when earth-fault protection must work correctly on both sources. We confirm this against your earthing system.
Typically 5–15 seconds from mains failure to load on generator, most of which is engine start and stabilisation. Timers are adjustable to avoid nuisance starts on short dips.
