Hamolar 2 Pack 12V 200A Heavy-Duty Relay Switch for Split Charging

Meet the Hamolar 2 Pack 12V 200A Continuous Duty Relay Switch, engineered for demanding power switching in trucks, boats, and marine environments. This pair delivers identical high-capacity relays, simplifying multi-circuit wiring for split charging, battery management, or accessory control. With a 200A switching capability and a 12V DC coil (14V max), they integrate smoothly with typical automotive electrical systems, offering reliable on/off control without fuss. Built to endure tough conditions, the relays feature durable terminals, silver-plated internal contacts, and protective components that support stable performance when the environment gets rough.

Designed for durability and reliable performance

The 12V relays use high-quality alloy terminals and silver-plated contacts for firm, low-resistance connections. The 200A coil capacity is geared toward high-current tasks, while the robust, heavy-duty design stands up to vibration and wear common in automotive and marine applications. A flame-retardant housing adds an extra layer of safety and long-term lifespan, and the kit includes gaskets to help seal connections against moisture and dust. These details work together to provide a solid, dependable control point in your electrical system.

Versatile use for split charging and universal 12V setups

Whether you’re managing a split charging setup, powering auxiliary accessories, or upgrading a vehicle’s power switching, these relays offer a practical solution. The four-terminal SPST (Single Pole Single Throw) configuration keeps wiring straightforward, while the 12VDC coil with a 14V max rating ensures compatibility with common 12V systems found in trucks, boats, RVs, and more. The dual-relay package makes it easier to configure separate circuits without sharing the same contact path, helping you organize power flow more cleanly.

What’s in the box and how installation benefits

• Two relays with matching 12V/200A specifications for multi-circuit setups
• Durable terminals and gasketed installation accessories for easier mounting
• Flame-retardant materials designed to support longevity in harsh environments
• Simple wiring with a four-pin SPST configuration for dependable control

In practice, you may notice more organized wiring and smoother power transitions in demanding environments. These relays do not guarantee specific results, but they are designed to offer a practical, robust option for high-current switching in vehicle and marine applications.
