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.


1.1 litre

10 kVA

The 403F-11G ElectropaK is a powerful but quiet 1.1 litre naturally aspirated 3 cylinder compact package that is designed to meet U.S. EPA Tier 4 Final emissions standards.

Compact and flexible

When you need power and reliability in a compact application, you can trust the 400 Series EP engines to deliver. Our engineers have carefully designed every component to minimise space. This can come in particularly handy in higher regulated territories where you need to consider size and space for aftertreatment solutions. Some models in the series also offer the convenience of switching between engine speeds and electrical frequencies to match your application and territory perfectly.

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.
