JOINAP 303-1AH-C-R1-U01 12VDC Ultra Micro ISO Relay – 20A SPST for Polaris RZR Slingshot Ranger (8 Pack)

Premium replacement relay for Polaris RZR and more

Meet the JOINAP 303-1AH-C-R1-U01 12VDC Ultra Micro ISO automotive relay, engineered to mirror the original manufacturer part in function and fitment. This compact unit is designed to slide into the fuse panel and manage power to critical systems such as fans and auxiliary circuits. While the listing shows a single relay, bundles like an 8-pack may be offered separately, so check the variant that matches your needs.

Key specifications at a glance help you compare quickly. The coil is 12 VDC, the contact form is SPST (one Form A), and the relay can switch up to 20 A with a modest 960 mW coil power. The design is built to endure demanding automotive environments, with a high temperature tolerance up to 125°C ambient.

• Ultra Micro ISO automotive relay design for compact, reliable power switching
• 12 VDC coil, SPST (1 Form A) contact form, 20 A rating
• Power consumption around 960 mW for efficient operation
• RoHS compliant and built to withstand hot engine bays
• Replaces Polaris part numbers 4011283 and 4016819 for compatible models

Fitment and usage details help you confirm compatibility before replacement. This relay is commonly used in a range of Polaris off-road machines — including several RZR models — and is intended as a direct replacement for the specified part number on the fuse panel. Always independently verify that your relay matches the same model number.

• Fits 2012-2015 RZR 570; 2010-2014 RZR 800 (all models)
• Fits 2011-2016 RZR 900 (all models); 2014-2016 RZR 1000
• General automotive use for power control in fans and auxiliary circuits

What you’ll notice in real-world use is a clean click when energized and consistent actuation under typical conditions, with a compact footprint that helps keep fuse panels tidy. This listing emphasizes a single relay per unit, while bundles may be available in other listings. If you need multiple units, you can multiply the pairing accordingly.

Packaging and value: each entry provides a ready-to-install relay that mirrors the original form factor, suitable for replacing a blown unit in a compact fuse panel. Look for the part number 303-1AH-C-R1-U01 and the 12 VDC coil to ensure a fit that matches your machine’s electrical layout.
