Review: Relais - Parfait , disponibilité comparativement au concessionnaire 👌 Review: Cross reference for Bobcat and Polaris - These work on Bobcat relays; mine is a 2021 U34 with diesel. Had to spend quite a bit of time cross referencing because I bought the U34 from an auction and someone had taken all the relays. Quarter of the cost of Polaris or Bobcat websites. Same exact markings also. ## Features - Part Number 303-1A-C-R1-U01 12VDC - Ultra-small ISO automotive relay (waterproof) - High Temperature withstand up to 125°C ambient - General purpose applications for automotive in power. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Z4G9K5L | | Brand | JOINAP | | Brand Name | JOINAP | | Coil Voltage | 12 Volts | | Connector Type | Screw | | Contact Material | Silver Tungsten | | Contact Type | Spst | | Current Rating | 20 Amps | | Customer Reviews | 4.7 out of 5 stars 807 Reviews | | Manufacturer | Join Auto Parts | | Maximum Switching Current | 20 Amps | | Model Number | 301-1A-C-R1-U03 | | Mounting Type | Panel Mount | | Operation Mode | Automatic | | Part Number | 301-1A-C-R1-U03 | | Specification Met | RoHS, ISO | | UPC | 745695370457 | | Wattage | 960 Milliwatts | ## Product Details - **Contact Type:** Spst - **Current Rating:** 20 Amps - **Mounting Type:** Panel Mount - **Brand:** JOINAP - **Operation Mode:** Automatic ## Images ![Automotive Purpose Relays 303-1AH-C-R1-U01-12VDC SPNO 20A 12VDC for Polaris RZR Slingshot Ranger Sportsman Cooling Fan Relay （ 4 Pack） - Image 1](https://m.media-amazon.com/images/I/61hgNRGefwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Relais *by E***O on 14 February 2025* Parfait , disponibilité comparativement au concessionnaire 👌 ### ⭐⭐⭐⭐⭐ Cross reference for Bobcat and Polaris *by B***G on 13 July 2026* These work on Bobcat relays; mine is a 2021 U34 with diesel.
