Perkins 1103A-33TG1: A 50 kVA Diesel Engine Base for Your Fleet

When a business buys a generator set, the alternator and the enclosure get most of the attention, but the engine is the part that decides how the machine behaves on site. The new Perkins 1103A-33TG1 offered as GEC-50571 is a compact, three-cylinder diesel unit rated at 50 kVA standby (46.5 kW) and 45 kVA prime, running at 1500 rpm with 400 V, 50 Hz, three-phase output.

Engine configuration

The 1103A series is built around a 3.3 litre vertical in-line block with three cylinders, turbocharged and water cooled, using direct fuel injection. Fuel is metered precisely and combustion is clean, which helps fuel consumption hold at 7.98 L/h at 75% load — a figure that matters directly to operating cost.

Speed control is handled by a combination mechanical and electronic governor. In practice this means the engine holds its frequency steady under changing load, useful where sensitive equipment or a shared supply is involved. The dry air cleaner keeps intake dust out of the cylinder, and the water-cooled radiator with fan keeps the block at a stable working temperature in hot climates and at high ambient loads.

Where a 50 kVA standby rating fits

Fifty kilovolt-amperes is a widely used working point for standby power. Typical applications include:

• Construction and contracting sites powering tools, site offices and lighting.
• Rental companies supplying mid-size sets for events, temporary installations and mobile power.
• Industrial facilities covering essential circuits during mains failures.
• Agriculture supporting irrigation pumps, barns and processing equipment.
• Data centres and telecom sites covering auxiliary and backup loads rather than full facility supply.

The prime rating of 45 kVA indicates continuous-duty capability at a lower output, giving operators flexibility between peak standby events and longer running periods.

Practical build features

Starting is provided by a 12 V, 3 kW starter, and the engine carries an oil capacity of 8.3 litres, which supports sensible service intervals in the field. Overall machine weight is 420 kg with dimensions of 1049 x 634 x 951 mm, and the set is supplied in a silent enclosure, measured at 88 dB(A) at 7 metres — helpful for urban and semi-urban installations.
