Overview
Brass Earth Blocks are precision-machined electrical connectors designed for safe earthing and distribution of current in multi-circuit installations. Available in 4-way and 8-way configurations, these blocks provide reliable mechanical strength, exceptional current-carrying capacity, and high resistance to corrosion.
Each unit is manufactured from high-conductivity Brass (CuZn39Pb3 / C36000 / CW614N / JIS C3604 / H59) with optional Nickel or Tin plating for enhanced oxidation protection and improved torque stability.
Brass 4 Way Earth Blocks
Brass 4 Way Earth Blocks are compact grounding components used in confined electrical panels or small terminal boxes. They feature four threaded ways for multiple wire terminations, machined with precision to ensure tight screw fit and minimal contact resistance.
Applications include lighting fixtures, small distribution boxes, automotive grounding kits, and electronic assemblies.

Nickel Plated Brass Earth Blocks
Nickel plating provides a durable, oxidation-resistant surface, improving appearance and mechanical integrity.
Advantages: Excellent wear resistance, low contact resistance, stable torque values, and extended service life even in coastal or humid environments.
Plating Thickness: 5–10 microns (as per ASTM B733 Type 2, Class 5)
Tin Plated Brass Earth Blocks
Tin plating improves solderability and corrosion resistance in moisture-prone installations.
Used widely in marine, solar, and industrial electrical control systems, Tin-plated variants comply with ASTM B545, BS 1872, and RoHS requirements.
Plating Thickness: 5–8 microns
Brass 4 & 8 Way Terminal Bars
Brass Terminal Bars (also known as Neutral or Earth Bars) are available in both 4-way and 8-way versions, precision machined for uniform torque control and maximum current conduction. Each terminal bar can be customized with or without mounting holes, screws, or insulating bases.
Customization:
Any hole configuration or pitch
