Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network. Regardless of whether you decide to receive these marketing communications, Caterpillar will continue to send service/transactional messages, including those that have to do with any accounts that you may have with us.

Overview

Producing reliable power from 2750 kVA to 3000 kVA (3100 kVA without fan) at 50 Hz, our 3516E diesel generator sets are made to match your mission critical, standby and prime applications, and meet our quality standards. We've engineered each to ISO 8528-5 transient response requirements and to accept 100 percent rated load in one step. Seismic certification is also available for select models, maintaining power after unexpected disturbances. The integrated control system, including ATS and switchgear, ensures a consistent power supply and connection to your fleet through on-site and remote monitoring options. Our EMCP 4 control panel provides flexible options, with a user-friendly interface, putting your management and diagnostic tools in one. The EMCP 4.4 controller provides multi-generator set paralleling capability, giving you the ability to add generator sets to provide expanded capacity and generator set redundancy to match your requirements. No two power needs are the same, which is why we offer a broad range of accessories and bolt-on system expansion attachments. Find flexible packaging options to work with your spatial requirements and environmental conditions. Our 3516E generator sets are built to take on power challenges — customize them to take on yours.
