Ensure terminal nuts are tightened to approximately 8Nm (max 12.5Nm). Recommended for use with up to 120mm² (4/0 AWG) cables to maintain full 275A continuous rating. Questions & Answers Is this switch suitable for 48V lithium systems? Yes, the BS-275 is rated for systems up to 48V nominal (60V max), making it ideal for the latest LiFePO4 battery banks used in solar and high-end marine setups. How do I know if it is compatible? If your system requires a continuous current of 275A or less and operates within the 12V-48V range, this switch is compatible. Please check your inverter's maximum continuous draw to verify. What is the benefit of the removable knob? The knob can be turned to a specific 'Remove' position (30° past OFF), allowing you to physically take the key with you. This serves as a safety lockout during maintenance and a theft deterrent for vehicles. Note: Distributed by Solarika. Please verify your system's current requirements against the specifications above before purchasing.
