MODEL 340: 12-VOLT SEALED 40-AMP SPDT RELAY
HEAVY-DUTY ELECTRICAL MANAGEMENT
Safeguard your onboard air infrastructure and optimize high-amperage switching circuits with the premium Kleinn Model 340 Electrical Relay. At the core of this heavy-duty control module is an industrial-tier 12-volt, 30/40-amp Single Pole Double Throw (SPDT) configuration designed to handle high current spikes from heavy automotive compressors and electronic solenoid horns. Engineered to safely isolate your cabin control toggles from heavy direct battery currents, this vital safety component stabilizes voltage lines to preserve high-flow pneumatic accessory cycles.
SEALED PROTECTION FOR ROUGH TRAILS
Unlike standard unsealed automotive relays that quickly short out when exposed to engine bay steam, road grime, or trail water, the Model 340 features a fully sealed protective casing. This weatherproof construction seals the internal contact pins from moisture penetration and atmospheric degradation, ensuring a reliable, spark-free mechanical link. Its versatile 5-post architecture facilitates clean terminal assignments for complex pneumatic loops or automated auxiliary wiring tracks.
Why Choose the Model 340 Relay?
- Weatherproof Sealed Shell: High-durometer external housing blocks dust fields, mud spray, and moisture, protecting critical contacts in exposed chassis runs.
- 40-Amp Power Threshold: Handles heavy high-amp load currents up to 40 amps to ensure clean, continuous current delivery to demanding compressor motors.
- 5-Post SPDT Flexibility: Single Pole Double Throw framework provides both Normally Open (NO) and Normally Closed (NC) wiring paths for maximum utility.
- Switch Isolation Security: Safely triggers high-draw components using minimal dashboard switch amperage, extending the life of cockpit electronics.
THE VERDICT:The definitive heavy-duty upgrade to prevent electrical failures on the trail. The Model 340 packs absolute element isolation and a robust 40-amp threshold into a rugged, compact footprint built to handle severe under-hood environments.
What's in the Box?
