Are Class 8536 Type S starters in NEMA 7/9 enclosures also suitable for NEMA 3R applications?

The Spin-Top aluminum enclosed starters are UL Listed and may be marked as ``Raintight.`` So, even though enclosure types 7 & 9 are generally regarded as suitable for ``Indoor Hazardous Locations,`` they were evaluated by UL and found to be acceptable for type 3R applications when a drain and breather (form Y41) are installed.

The bolted cast aluminum enclosed starters are not UL Listed but are suitable for type 3R applications when a drain and breather (form Y41) are installed.

The bolted cast iron enclosed starters are UL Listed and are suitable for type 12 indoor applications but not type 3R applications.
