Featuring 103 microfarads capacitance and a robust 330V withstand voltage, it fits multiple popular models including Pentek, Myers, and Sta-Rite. Its compact snap-in design ensures easy installation and long-lasting performance, making it the go-to choice for professional-grade motor control maintenance. ## Description The start capacitor in a motor control box is considered a consumable part. Capacitors tend to lose capacitance over time and/or use, and need to be replaced when the capacitance drops below the described range. This start capacitor is fully compatible for replacing Pentair Pentek, Myers, Sta-Rite start capacitors with part number: U17-1424 , U17-1424-R , U17-2074, CMCI 86MFD+20%/-0% , Start cap in Tuhorse TCB20M230, and other control boxes that use the same rating start capacitor. Some older control box's start capacitor is 270V, this 330V, higher withhold voltage version is the same or better. We now stock the 330V version only. ## Features - Quality capacitor made in the USA by Barker Microfarads (BMI) for Tuhorse Electric - Compatible Replacement part for Pentek Myers Sta-Rite U17-1424 , U17-2074 and the start capacitor in TCB20M230 - 330V withstand voltage, also compatible with the 270V version. - 86-103 MFD (uF) 330VAC 50/60Hz, with discharge resistor - 3.35" height x 1.85" diameter ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0CMTKW9YZ | | Best Sellers Rank | #157,968 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #1,420 in Industrial Electrical Capacitors | | Brand Name | Tuhorse | | Capacitance | 103 Microfarad | | Customer Reviews | 4.1 4.1 out of 5 stars (9) 4.1 out of 5 stars | | Included Components | capacitor | | Item Dimensions W X H | 1.85"W x 3.35"H | | Item Shape | Round | | Item Type Name | Motor start capacitor | | Manufacturer | Tuhorse by BMI | | Material Type | Copper | | Maximum Voltage | 330 Volts | | Model | 091A086B330BD4X | | Mounting Type | Snap-In Mount | | Operating Voltage | 330 Volts | | Part Number | TH086BMIU17-2 | | Unit Count | 1.0 Count | | Upc | 616576235830 | ## Product Details - **Capacitance:** 103 Microfarad - **Brand:** Tuhorse - **Material:** Copper - **Shape:** Round - **Operating Voltage:** 330 Volts ## Images ![BMI 86-103 MFD (uF) Motor Start Capacitor, Compatible Replacement Part for U17-1424, U17-2074 and The Start Capacitor in TCB20M230 Made in USA by BMI for Tuhorse Electric - Image 1](https://m.media-amazon.com/images/I/61CsQON2sZL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by on Reviewed in the United States April 2, 2024* I had a submersible well pump come loose from the water pipe and was hanging by the electrical wires (not that uncommon) so the pump ran continuously and eventually burned up the capacitor in the control box.
