660kVA CAT Diesel Generator DE660 ENCL

The DE660 is a Cat C18 diesel generator set with a Leroy Somer alternator, rated at 660 kVA / 528 kW standby and 600 kVA / 480 kW prime at 400 V.

Key features

• The set carries both a standby and a prime rating, so it can be sized against either one.
• The kW figure is 80% of the kVA figure in both ratings, a power factor of 0.8, so check loads against both figures.
• It is a stationary set, intended for a fixed installation.

Run time is 11.7 hours at 75% load. Noise is 72 dBA at 7 m, which can be checked against a site noise limit.

What it will run

Start with the load schedule: the running load on every circuit, the starting demand of the largest motors (several times running current is common), and the phase arrangement your equipment needs. Confirm that the equipment is rated for 400 V. An engineer or electrician should assess the schedule before the set is specified. Any connection to the switchboard, including a changeover or transfer switch, must be installed by a licensed electrician. Send us your load list and we will help with sizing.

The DE660 suits manufacturing and processing sites, large commercial buildings, cold storage and logistics hubs, pumping and water infrastructure, and major construction projects that need standby power.
