178B7285

Product Description:

The 178B7285 cooling drive stands out in the Danfoss AKD Adaptive Cooling Drives family, made for industrial sites where reliability comes first. Power is handled with a rated input voltage of 3 x 380-500 V AC, so it runs steady on common three-phase supplies. The drive can supply high overload output power up to 29.4 kVA if needed, and holds an efficiency of 0.96 to keep energy costs lower when running nonstop. The model allows for two enclosure options, IP20 or IP54, and those choices give some freedom based on how rough the environment gets.

Mounting this drive doesn’t create a challenge since both IP20 and IP54 housing types stick close to the same footprint in most control panels. In the heavier-duty IP54 package, the weight clocks in at 42 kg, making it easier to handle during servicing without big equipment. Devices that live with light dust or splashes, like variable-speed chillers, get real value from IP54 protection, while less-harsh spaces can use IP20 for less bulk. Current demands change by voltage—44 A at 380 V or 41 A at 460 V—giving predictable power usage numbers whether installing locally or sending abroad.

Connections take standard cable cross-sections, with 16/6 mm² or 10/8 mm² specs suiting both power and motor lines so setups don’t get tricky for installers. Pre-fuse sizing has dual limits at 63/60 [-]/UL A, letting sites use main circuit protection sized to local code. Cooling builds in tough components, and a power loss at max load of 655 W shows most of the juice gets put to work, not wasted as heat. For installations needing regular overload handling or room for high motor loads, the 178B7285 cooling drive provides muscle and puts out steady control shifts, all with the stamp of Danfoss quality behind it.
