The Perkins 403 range of electric power (EP) engines delivers the same compact benefits of its 2 cylinder stablemate, but takes a stride forward in terms of noise, refinement and power. The 3 cylinder range offers excellent power density and superb fuel economy and is designed to meet your power generation needs in both unregulated territories where extreme conditions are likely, and higher regulated territories with more stringent emissions standards.


1.5 litre

13-20 kVA

The 403A-15G ElectropaK is a powerful but quiet 1.5 litre naturally aspirated 3 cylinder package that is designed for use in unregulated territories.

Efficient, quiet and powerful

The pressure on end users to reduce the fuel consumption of their machinery favours the 3 cylinder 403. Its power density, durability, fuel efficiency and quiet operation set it apart from similar sized competitors' engines. The 403 range's quiet operation makes it an excellent option where noise is a concern, particularly if you're operating in urban areas.

Lower operating costs

The reliability of the 403 range, its uncomplicated indirect injection fuel system, ease of installation and warranty offering all combine to keep your ownership costs to a minimum. As the 400 Series is built on a common engine platform, you can also upgrade easily and affordably.
