Product Details
BB275-T5M10-C-BR provides 5 x M10(3/8″) stud connections with a 275 A current rating. The stud-only layout suits wiring assemblies built around cable lugs, without adding small screw terminals that are unnecessary for that connection format. Black and red versions share the same connection layout.
BB275-T5M10-C-BR / mixed terminal configuration.
- 01 A consistent stud interface
5 M10(3/8″) studs give the assembly 5 defined lug positions. Using one stud diameter makes the mechanical connection format clear when selecting compatible cable lugs. - 02 Specified bus material
The copper bar forms the common conductive path. Stainless steel studs secure the lug connections. - 03 Covered connections for protected installations
A protective cover shields the terminal area. The cover is not a substitute for a sealed electrical enclosure where water or conductive contamination is present.

Current rating applies to the product, not to each connection. Provide circuit protection separately. Inch sizes are approximate references, not interchangeable thread specifications.
Compare Connection Layouts and Ratings
Compare this model with other connection formats in the DAIERTEK range. Matching terminal counts do not establish mechanical interchangeability.

Counts are totals for each listed assembly. Dual assemblies are not rated by adding two current values. Black/red options do not mean that a pair is supplied.
Common DC Connections in Practice
Typical uses for protected vehicle and onboard electrical installations.
Off-road accessory wiring
Organize common accessory connections with the 5 x M10(3/8″) stud layout. Locate the bar in a guarded, dry compartment rather than an exposed vehicle area.
RV auxiliary electrical systems
Provide an accessible common connection point within a protected onboard electrical compartment. Plan the connections around the required polarity and provide circuit protection separately.
Application examples describe potential installation contexts, not verified fitment to a particular vehicle. Keep live connections protected from water, conductive debris and accidental contact.
