The Type 3R Package is specifically designed for Yaskawa Variable Frequency Drives.

The Type 3R outdoor duty package is not just a "NEMA 3R" self-declared rating. Yaskawa went beyond its own stringent testing by asking Underwriters Laboratories Inc. (UL) to test and certify this package to meet UL 508A Type 3R for outdoor use to provide a degree of protection against falling rain; undamaged by the formation of ice on the enclosure.

The Type 3R Package is designed for applications such as Cooling Towers, Rooftop AHUs or Exhaust Fans, Irrigation Pumps and Water/Wastewater Pumps.

Designed to operate in ambient temperatures up to 104ºF (40ºC) without air conditioning with space for several commonly used options, makes this the preferred outdoor duty package for variable frequency drives. A standard option is available for ambient temperatures up to 122ºF (50ºC) without air conditioning.

There are many standard features of the Yaskawa Type 3R Package, such as:

• The circled areas use the same filter media. This decreases the number of filter media part numbers which lowers cost of ownership. The filter media is easy to replace which lowers the overall maintenance cost of this outdoor duty package.
• Dual ground lug - one lug for earth ground, one lug for utility ground.
• Standard practice in the Yaskawa Type 3R Package is to provide filter media at exhaust ports. The filter media brackets include integral filter supports.
