Electrical busbar for high-current distribution centralises multiple connections with a 250A continuous rating. Reliable conductivity and a heat-resistant base give installers confidence in compact distribution panels. Is the Blue Sea Systems MaxiBus BusBar the right choice for installations that need a compact, high-capacity distribution point?
⚡ At a Glance
- • Current Capacity: Continuous rating 250A AC/DC, max voltage 300V AC / 48V DC
- • Best for: Centralising multiple high-current connections in compact distribution panels within rated voltages
- • Not ideal for: Circuits that require more than 250A continuous or exceed 300V AC / 48V DC
MaxiBus 2127 is a 250A MaxiBus busbar with multiple studs and a tin-plated copper conductor. UL 94-V0 rated base material resists high heat and two mounting holes accept #10 (M5) screws.
Improved Heat Resistance – With UL 94-V0 rated base material
Base material carries a UL 94-V0 rating, specified for low flammability and resistance to ignition at elevated temperatures. The rating indicates a material designed to resist heat rather than melt or sustain combustion.
Greater safety in confined electrical panels under load and reduced risk of base deformation during prolonged operation.
Lower Voltage Drop – Thanks to tin-plated pure electrical copper construction
Conductor is tin-plated pure electrical copper, chosen for high conductivity and improved corrosion resistance at connection points. Tin plating helps protect bare copper from oxidation that increases contact resistance.
More efficient current transfer with reduced losses at terminals and longer-lasting, reliable connections in challenging environments.
Flexible Wiring Options – With multiple terminal studs and secure mounting points
Product descriptions reference a 250A MaxiBus with 4 studs (part number 2127) and list terminal studs as 6 x 5/16"-18; two mounting holes accept #10 (M5) screws for panel attachment. Stud sizing and mounting provision support bolted connections.
Allows grouping of several heavy-gauge cables while enabling firm attachment to distribution panels for tidy, serviceable installations.
✨ The 4 Key Reasons for Blue Sea Systems MaxiBus BusBar
- Tin-plated pure electrical copper - Minimises voltage drop and maintains conductivity in corrosive conditions
- UL 94-V0 rated base material - Withstands higher temperatures, reducing fire and deformation risk
- 6 x 5/16"-18 terminal studs - Accepts multiple heavy-gauge connections for neat, robust wiring
- Two #10 (M5) mounting holes - Secures busbar firmly to panels with standard fasteners
