Victron Energy 250A Busbar with Removable ABS Cover, 70VDC Max, 5/16-Inch Stainless Steel Studs, Available in 4 Stud, 6 Stud, or 2 Stud Plus 6 or 12 Screw Terminals

About the Victron 250A Busbar

This busbar gives you a clean, code-friendly way to consolidate multiple battery, inverter, charger, and load connections at a single point. Tin-plated copper construction provides low resistance and corrosion resistance. The removable ABS cover snaps over the terminals after installation to prevent accidental shorts and meets UL 94 V-2 for flame retardance. The base material is rated to the higher UL 94 V-0 standard.

Choosing the Right Configuration

The 4-stud and 6-stud versions provide all 5/16-inch stainless studs for heavy cable connections (battery cables, inverter feeds, MPPT outputs). The 2-stud plus 6-screw and 2-stud plus 12-screw versions combine two heavy stud terminals with smaller 10-24 screw terminals, which is useful when you need to distribute power from a battery bank to multiple smaller loads (lighting circuits, fans, accessories) without running every connection through a separate fuse block. The 2P versions also use a heavier copper bus strip (6.35 x 25mm) compared to the 4P and 6P versions (5 x 24mm).

Installation

Tighten the stud nuts to 110 lbf·in (13 N·m). Under-torquing causes voltage drop and heat at the connection. Over-torquing can deform the soft tin-plated copper nut or strip the threads. Use a torque wrench and verify connections after the first heat cycle.

The busbar does not include screws or hardware for mounting it to a panel or surface. Use #10 or M5 fasteners through the mounting holes in the base, sized to your panel material.
