4.5kVA Yanmar Diesel Generator GYD3500E-3

The GYD3500E-3 is a 4.5kVA (3.5kW) three phase Yanmar diesel generator at 415V and 50Hz. Its Yanmar L70 is an overhead valve, single cylinder diesel running at 3000 rpm, with recoil and electric start. The alternator is a brushless AC synchronous type with Class H insulation, and the outlets are one 10A 415V and two 15A 240V sockets.

Key features

• Recoil and electric start give you two ways to start the engine, so a flat battery does not leave you stuck.
• One 10A 415V outlet and two 15A 240V outlets let you run three phase and single phase equipment from the same set.
• A brushless AC synchronous alternator with Class H insulation keeps harmonic distortion below 5%.
• A heavy duty roll frame guards the engine and alternator against knocks.
• A 2 year limited engine warranty applies.

The 3.5 litre tank gives 2.9 hours at 100% load and 3.8 hours at 75% load, so it suits short outages and intermittent work. Noise is 80 dB(A) at 7 m. Engine oil capacity is 1.1 litres.

What it will run

This is a three phase set, so it should be sized around the equipment on site rather than a handful of household appliances. It typically suits small three phase motors and machines on the 415V outlet, plus lighting and power tools on the 240V outlets, with the combined load kept inside 3.5kW. Motors draw a surge at start, so check the compliance plate on each machine for its running and starting figures and allow for the largest motor starting. Ask an electrician or engineer to confirm how the load is shared across the phases. Any connection to fixed wiring must go through an inlet and changeover switch installed by a licensed electrician. Send us your load list and we will help you size it.

The GYD3500E-3 suits small workshops, light commercial and trade sites, farms and site sheds that need three phase power for backup or intermittent work. It is built for standby use and is not rated for prime or continuous duty.
