Brass Terminal Block — T003 Series
High-conductivity brass bar on insulated nylon base for neutral/earth distribution.
4–18 ways; 6×9 mm (M4) or 8×12 mm (M5) bores.
Compact footprint, low resistance, easy inspection and re-torque.
Ideal for distribution boards, control panels, and OEM switchgear.
Overview
The brass terminal block T003 is a compact, low-resistance solution for consolidating neutral and earth conductors in distribution boards and control panels.
Machined from solid brass and seated on a rigid insulated base, brass terminal block T003 keeps wiring short, labeling clear, and service checks fast in tight enclosures.
With bore options of 6×9 mm (M4) and 8×12 mm (M5) and way counts from 4 to 18, the brass terminal block T003 adapts to residential, commercial, and light-industrial layouts.
When panel builders require repeatable torque and stable contact quality, brass terminal block T003 provides a dependable footprint that integrates with standard accessories.

Dimension
Applications
Use brass terminal block T003 in consumer units, OEM control cabinets, machine panels, and PV sub-assemblies where a compact neutral or earth consolidation point reduces clutter and speeds commissioning.
Selection Guide
Pick 6×9 mm with M4 screws for compact conductors; choose 8×12 mm with M5 when cable size or current margin is higher.
For boards with many branch circuits, brass terminal block T003 in 16–18 ways minimizes jumpers and shortens runs.
Installation
Mount the base on a flat surface, confirm earthing strategy, and route feeders before tightening.
When space is tight, brass terminal block T003 can sit near the incoming neutral or PE stud to simplify labeling and testing.
Maintenance
Re-torque terminal screws on scheduled intervals, inspect contact surfaces, and verify base fasteners.
With these simple checks, brass terminal block T003 maintains consistent performance over years of thermal cycling.
FAQ
What conductors fit the T003 series?
Use 6×9 mm bores with M4 screws for compact cross-sections, and 8×12 mm with M5 screws for larger conductors.
Neutral or earth?
Both. The bar can be wired as a neutral link (N) or an earth bar (PE) depending on the panel design.
Any torque guidance?
Apply manufacturer-standard torque for M4/M5 screws and re-check after initial thermal cycles as part of routine maintenance.
