Description
OEX ACX3210 150A Distribution Block 4x M8 Stainless Steel Terminals Black Tin Plated Copper Bus Clear Cover 48V DC
The OEX ACX3210 is a 150A distribution block with four M8 terminal studs, combining a tin plated copper bus, stainless steel terminals and hardware, nylon base and clear protective cover in a single compact unit. It allows a single heavy gauge input cable to feed multiple output circuits through four independent M8 studs, eliminating complex wire splicing and reducing connection points. Rated to 150A continuous and 48V DC maximum, it suits 12V, 24V and 48V DC systems. ISO 9001 certified manufacturing with in-house testing at OEX's Brisbane facility. Covered by a one year warranty.
Product overview
A distribution block simplifies wiring by providing a central point where one heavy gauge supply lead connects and multiple output circuit cables distribute from independent terminals. Rather than running multiple heavy cables from the battery or splicing wires, the ACX3210 accepts a single input and distributes it across up to four circuits via separate M8 stud terminals. This reduces connection points, keeps wiring organised and makes future circuit additions, removals and troubleshooting straightforward.
The 150A continuous rating and 48V DC voltage rating cover 12V passenger vehicles, 24V commercial trucks and heavy equipment and 48V specialised systems. Stainless steel terminals and nuts resist corrosion in marine, off-road and industrial environments. The tin plated copper bus provides good conductivity and corrosion resistance compared to bare copper. The nylon base provides electrical insulation and mechanical strength, and the clear protective cover shields the terminals from accidental short circuits, debris and moisture while allowing visual inspection of connection integrity without removing the cover.
Features and benefits
150A continuous rating: Accommodates high-current auxiliary circuits including lights, winches, compressors and inverters without exceeding safe operating limits.
4x M8 terminal studs: Four independent terminals allowing one input to distribute to up to four output circuits. Accepts cable terminal lugs compatible with M8 studs across a range of cable gauges.
Stainless steel terminals and hardware: Superior corrosion resistance in marine, off-road and industrial environments exposed to moisture, salt spray and chemical contaminants.
Tin plated copper bus: Better conductivity and corrosion resistance than bare copper, minimising contact resistance and voltage drop across all terminal connections.
Nylon base with clear protective cover: Electrically insulating nylon base with a clear cover protecting terminals from accidental short circuits, debris and moisture. Visual inspection of connections possible without removing the cover.
48V DC maximum operating voltage: Compatible with 12V, 24V and 48V DC systems including passenger vehicles, commercial trucks and specialised equipment.
ISO 9001 certified manufacturing: In-house product testing at OEX's Brisbane facility to standards developed for Australian and New Zealand conditions.
One year warranty: Covered by a one year OEX warranty.

Frequently asked questions
What is a distribution block used for? A distribution block allows one heavy gauge input cable from the battery or main power source to feed multiple output circuits through independent terminals. This eliminates complex wire splicing, reduces the number of connection points and provides organised, centralised power distribution for auxiliary lights, accessories and equipment without running multiple heavy cables directly from the battery.
What size cables suit the M8 terminal studs? M8 terminal studs accept cable terminal lugs across a range of cable gauges. For the 150A total rating, match cable gauge to the current draw of each individual circuit: typically 8 to 10 AWG for circuits under 40A, 6 AWG for circuits up to 60A, and 4 AWG or heavier for higher current circuits or longer cable runs to minimise voltage drop.
Can this distribution block be used on 12V and 24V systems? Yes. The 48V DC maximum operating voltage makes the ACX3210 compatible with 12V passenger vehicles, 24V commercial trucks and heavy equipment and 48V specialised systems. The rating reflects the maximum voltage the insulation can safely handle.
How should this distribution block be installed? Mount the block in a location protected from direct water spray and excessive heat, securing the nylon base firmly. Connect the input cable from a fused power source to one terminal, then connect output circuits to the remaining terminals. Install appropriate fuse or circuit breaker protection between the battery and the distribution block input, and fuse each output circuit to match the connected load and cable gauge.
What makes this distribution block suited to Australian conditions? OEX conducts in-house product testing at its Brisbane facility to standards developed for Australian and New Zealand conditions. Stainless steel terminals and tin plated copper bus provide corrosion resistance in moisture, salt spray and chemical exposure. The nylon base and clear cover protect connections from debris and moisture. ISO 9001 certified manufacturing ensures consistent quality.
