Reliance Electric 45RS Motor Overload Protector Assembly

Reliance Electric 45RS Motor Overload Protector Assembly is a replacement MOP assembly used to provide motor overload protection in Reliance Electric equipment. The 45RS MOP Assembly is listed as a spare part for Reliance Electric motor starters and drives and is available as refurbished units from distributors and refurbishers, including online listings that catalog the part as 45RS MOP Assembly. This assembly sits within Reliance Electric’s legacy motor-protection lineup and is encountered in refurbishment and surplus markets as a way to restore the original protective function in older installations. Because compatibility depends on the original control gear configuration, customers should verify the part number against the equipment’s bill of materials or cross-reference it with the supplier before purchasing. Sourcing the 45RS from reputable refurbishers or authorized distributors helps maintain the intended protection in legacy Reliance Electric systems without replacing broader starter or drive assemblies.
