The Ampper AM-CBs03PM Battery Disconnect Switch is a versatile and essential component for various electrical systems, suitable for 12V and 48V applications. This premium quality disconnect switch is designed to offer safe and secure battery disconnection, ensuring the protection of both the battery and the connected electrical components.
The AM-CBs03PM is a panel-mounted switch, which provides an easy-to-access and convenient solution for battery disconnection. It features a compact design with dimensions of approximately 1.4 inches by 1.7 inches by 1.2 inches (LxWxH), making it an ideal fit for most panels or control boxes.
This disconnect switch comes with three keys (Position 1: ON for both circuits, Position 2: OFF for both circuits, and Position 3: ON for circuit 1 and OFF for circuit 2) that enable users to selectively manage power flow to different circuits. When switching to Position 2 (both circuits off), the switch effectively disconnects the battery from the circuit, preventing accidental power draw or short-circuits. This is particularly advantageous when performing maintenance on electrical systems or changing batteries.
The AM-CBs03PM boasts a robust construction with a flame-retardant, impact-resistant, and sealed polycarbonate body. Its high-quality terminals are made of gold-plated brass for improved conductivity, longevity, and durability. The switch is engineered to withstand the rigors of continuous operation, and it is tested to meet or exceed the standards for insulation resistance, contact resistance, and current carrying capacity.
The Ampper AM-CBs03PM Panel Mount 1-2-Both-Off Battery Disconnect Switch is suitable for a wide array of applications, including RVs, boats, agricultural machinery, golf carts, solar systems, and various industrial equipment. It is ideal for anyone seeking a reliable, durable, and user-friendly solution for battery disconnection and management in their off-grid projects.
Incorporating the AM-CBs03PM battery disconnect switch into your electrical setup is effortless, as it can be easily wired into the system using the provided screw terminals. The switch requires a low operating voltage of 12V DC or less, making it an efficient and energy-saving solution for your electrical needs. For added peace of mind, the switch's heavy-duty design and durable construction ensure years of reliable performance.
