This is the required starter with capacitors for a Grundfos MS4000R series 904L stainless steel submersible 2.2 kW single phase motor. The starter enclosure is rated at IP24 so it will always require additional protection against weather, moisture and insects. Insects love to find a warm piece of electronics and starters are no exception so we strongly recommend that you purchase one of our weatherproof, waterproof, dustproof and insect-proof IP65 steel enclosures.
