Product Overview
The Sonzrod 4‑Pin Relay is a high‑load, 30 Amp automotive relay designed for air‑conditioning compressors and radiator fans in vehicles from 2010 to 2020. Constructed with silver‑alloy contacts, it offers low resistance (<50 mΩ) and excellent conductivity. The plug‑in mounting type matches standard SPST relay sockets, and the housing meets OEM specifications with an IP67 rating, protecting against water, dust, and extreme temperatures ranging from –40 °C to 125 °C. Two SKUs are available: one with a wiring harness socket and one without, allowing flexible installation.

FAQ
Will this relay fit my 2015 sedan?
Yes, the relay is designed for standard 4‑pin SPST sockets found in most 2010‑2020 sedans. Verify the socket size in your vehicle’s service manual or by checking the VIN.
Do I need the wiring harness socket?
The socket version simplifies wiring connections and reduces the chance of mis‑wiring. Choose it if you prefer a cleaner install; the non‑socket version works equally well with existing wiring.
Is the relay waterproof?
With an IP67 rating, the relay is protected against immersion in water up to 1 meter for 30 minutes and is dust‑tight, making it suitable for harsh under‑hood environments.
Can this relay be used for other high‑load accessories?
While optimized for A/C compressors and radiator fans, the 30 A rating makes it suitable for other 12 V high‑current accessories such as electric water pumps or auxiliary lights.
What warranty does Sonzrod offer?
Sonzrod provides a one‑year limited warranty covering defects in materials and workmanship, ensuring peace of mind for your purchase.
