Weasch 2 Pack 12V 30A 4-Pin Normally Closed Relay Kit with 12AWG Wire

Weasch 2 Pack 12V 30A 4-Pin Normally Closed Relay Kit with 12AWG Wire

• 【CORE SPECIFICATIONS】Standard universal 4-Pin SPST (Single Pole Single Throw) Normally Closed (NC) relay. Designed exclusively for 12V DC automotive electrical systems. Keeps the circuit connected by default and safely breaks power when the coil is triggered
• 【PREMIUM CONTACTS】Upgraded with Silver Tin Oxide (AgSnO2) alloy contacts. This advanced material provides superior electrical conductivity, excellent resistance to arc erosion, and prevents contact welding for a much longer lifespan compared to standard relays
• 【SAFE LOAD CAPACITY】Engineered for a 20-30 Amps continuous working load (40A peak). Important Note: To protect your custom wiring and ensure maximum reliability, Never exceed its capabilities. Try to stay 10 to 15% below the rated value
• 【HEAVY-DUTY HARNESS】Includes a pre-wired, color-coded pigtail harness for quick installation. Equipped with thick 12 AWG tinned copper Tin wires for the main power circuit (Pin 30/87a) and 18 AWG wires for the coil control (Pin 85/86)
• 【DEDICATED NC APPLICATIONS】Specifically engineered for custom wiring where power needs to be interrupted. Ideal for starter kill switches, auto alarm integrations, and remote start modules. An essential power-cutoff relay for upgrading 12V electrical systems in heavy-duty trucks, vans, motorcycles, boats, and marine equipment
