750kVA-900kVA Cat 3412C

Overview

The Cat 3412C diesel generating set ranges from 750kVA to 900kVA as both an open generator package, and low noise sound attenuated enclosure. Designed for maximum performance and minimum fuel consumption, this set provides a single-source supplier capable of running at 45 degrees prime power with no de-rate. The EMCP 4.2 control panel offers fully featured power metering with communications via Modbus RS-485, SCADA, or CAN data links.  Worldwide parts availability through your Caterpillar dealer with over 1800 dealer branch stores operating in 200 countries. It's not just quality that matters but customization, choose from a broad range of accessories and bolt-on system expansion attachments. Discover our upgradeable packaging options to work with your spatial restrictions and environmental conditions. Our 3412C generator sets are developed for such prerequisites, so that you can meet your specific power needs.
