The 250A protection box is a robust electrical safety interface designed to protect high-capacity storage parks. This product is a DC disconnect box used to isolate and protect your batteries from accidental overloads and short circuits.

This accessory is specifically compatible with Pylontech batteries (US2000C, US3000C, US5000 series). This device secures the connection between the battery bank and the inverter by integrating seamlessly with high-power systems operating at 48V, such as Victron MultiPlus-II inverter-chargers or WKS solutions.

Equipped with a 250A isolator, this box also facilitates maintenance operations by allowing the circuit to be physically disconnected without disconnecting the cables. Its robust housing provides durable mechanical protection for large-section cables, which are essential for supporting high discharge currents.

Technical advantages of the box:

  • Breaking capacity: 250A rating suitable for rapid discharges from lithium battery banks.
  • Increased safety: Effective protection of Pylontech cells and inverter electronics.
  • Simplified maintenance: Integrated disconnect switch for quick and safe power-off.
  • Compliance: Meets safety requirements for residential energy storage installations.
