40 MFD 370V Motor Run Capacitor | RD-40-370 / 35-249-1000

Key Benefits + Electrical Match

• 40 MFD motor run capacitor for compatible pool and spa motor applications.
• Rated for 370 VAC applications where the original capacitor calls for the same capacitance and voltage rating.
• Cross-reference identifiers include RD-40-370, CAP-2215, PRC40A, 5270-03, 17586340, 601407, and RD40370.
• Listed body size is approximately 1-3/4 in. diameter by 3-1/2 in. long, giving another useful check against the original capacitor.
• Electrical specifications, capacitor type, and physical fit must be verified before installation; do not select a capacitor by appearance alone.

Quick Product Summary

SKU 35-249-1000 is a 40 MFD, 370 VAC motor run capacitor used in compatible pool and spa motor applications. It is cross-referenced under identifiers including RD-40-370, CAP-2215, PRC40A, 5270-03, 17586340, 601407, and RD40370. A run capacitor supports normal motor operation after startup, so the replacement must match the required capacitance, voltage rating, capacitor type, and physical dimensions specified for the equipment. Before ordering, compare the ratings and size printed on or measured from the original capacitor, or verify the motor manufacturer's service information.

Best For

• Compatible pool and spa motors requiring a 40 MFD run capacitor
• Replacing an existing 370 VAC motor run capacitor with matching electrical requirements
• Service technicians matching replacement capacitors by rating, dimensions, and cross-reference number

Why This Matters

• Using the correct capacitance is important for proper motor operation.
• The replacement voltage rating must meet the equipment requirement.
• A start capacitor and a run capacitor are not interchangeable simply because they look similar.
• Matching the printed ratings, dimensions, and cross-reference numbers helps reduce incorrect replacement orders.

Common Signs You Need This / Use This When

• The existing run capacitor has been diagnosed as failed or out of specification.
• Your motor or equipment documentation specifies a 40 MFD, 370 VAC run capacitor.
• The original capacitor cross-references to RD-40-370, CAP-2215, PRC40A, or SKU 35-249-1000.

Product Specifications

Compatibility / Fitment Notes

Confirm the motor or equipment requires a 40 MFD run capacitor rated for 370 VAC before ordering. Also verify the capacitor type and physical fit because capacitors with similar outward appearance can have different electrical ratings or dimensions. Match the original capacitor label, body dimensions, or equipment documentation whenever possible.

Installation / Use Notes

Capacitors can retain a hazardous electrical charge even after power is disconnected. Replacement should be performed by a qualified person familiar with motor electrical service. Disconnect equipment according to the manufacturer's procedures, verify the correct capacitor specifications, and follow the equipment manufacturer's service instructions. Do not substitute a start capacitor for a run capacitor or install a capacitor with an unverified rating.

Buy with Confidence

Benchmark Pool Supply helps homeowners and pool professionals identify replacement pool equipment parts using part numbers, electrical ratings, dimensions, and practical service knowledge. For this capacitor, matching the 40 MFD rating, 370 VAC rating, capacitor type, physical size, and original equipment requirements before ordering is the best way to avoid an incorrect replacement.
