The ABB 086329-004 is a heavy-duty industrial terminal block assembly engineered for reliable power distribution and signal wiring in industrial control cabinets, PLC systems and automation equipment. It features a high-current carrying capacity, robust metal terminal construction and flame-retardant housing, ensuring stable electrical connection and safety in harsh industrial environments with vibration, temperature fluctuations and high interference. Designed for standard DIN rail mounting, it supports tool-free fast installation and wiring, with anti-loosening screw terminals and clear labeling to avoid wiring errors. Fully compatible with ABB AC500, Advant Controller 400 and other industrial control systems, it is an essential component for neat, reliable and maintainable industrial wiring systems.

The 086329-004 terminal block assembly features a high-conductivity copper alloy terminal construction with tin-plated contacts for low contact resistance and excellent corrosion resistance, supporting a high continuous current rating for industrial power distribution and heavy-duty load connection. The screw-type terminal design provides a secure, torque-adjustable connection for various wire gauges (solid/stranded), with anti-loosening thread locking to prevent connection failure caused by industrial vibration (compliant with IEC 60068 vibration standards). It has a wide voltage rating suitable for both low-voltage control circuits and medium-voltage power distribution, with reinforced electrical insulation between terminals to prevent short circuits and cross-talk.

The 086329-004 adopts a modular design for standard 35mm DIN rail mounting, with integrated snap-in locking clips enabling tool-free fast installation and removal from the DIN rail, maximizing control cabinet space utilization and simplifying on-site wiring. The housing is made of UL94 V-0 flame-retardant engineering plastic, providing excellent fire resistance and thermal stability for operation in -40°C to +85°C extreme temperature ranges. It features clear laser-engraved terminal labeling and color-coded identification for quick and error-free wiring, with a compact form factor supporting side-by-side mounting for high-density wiring applications. The terminal block is designed with a dust-proof cover to protect live contacts from dust and accidental contact, meeting IP20 industrial safety standards.

The 086329-004 terminal block assembly is fully compatible with ABB industrial control systems including AC500 PLC, Advant Controller 400, DCS systems and industrial drive equipment, providing a unified wiring solution for ABB automation products. It is also compatible with third-party PLC, HMI and drive systems, making it a versatile wiring component for mixed-brand industrial automation setups. Ideal for power distribution and signal wiring in various industrial sectors, it withstands harsh environmental conditions including high vibration, extreme temperatures and chemical exposure, ensuring reliable operation in critical industrial processes.
