The AS2.5BK is a 2.5 sq.mm angular feed-through spring clamp terminal block in black colour, designed for secure electrical wiring in industrial control panels, switchgear assemblies, PLC systems, machine wiring, and compact electrical installations. This terminal block is specially built for applications where space-saving wiring, secure conductor clamping, and organized cable routing are essential. Its angular wire entry design makes it highly useful in compact control cabinets and junction boxes where standard top-entry terminals may create wiring congestion.
One of the key advantages of the AS2.5BK is its angular wire entry orientation, which allows conductors to enter from the side at an angle rather than from the top. This helps reduce wire bending stress, improves cable routing, and keeps panel wiring neat and organized. In industrial applications where multiple wires are packed into limited space, angular terminal blocks simplify installation and reduce mechanical strain on conductors.
The black colour (BK variant) is used for circuit identification, negative DC wiring, control circuits, signal return wiring, or colour-coded electrical systems. Colour-coded terminal blocks help electricians and maintenance engineers quickly identify circuits, reducing troubleshooting time and minimizing wiring errors in industrial control panels.
The spring clamp connection system provides secure conductor retention without the need for screw tightening. The wire is inserted after operating the clamp with a screwdriver, and the spring mechanism automatically maintains constant contact pressure. This technology ensures vibration-resistant electrical connection and eliminates the risk of loose terminals caused by temperature changes or continuous machine vibration. This makes the AS2.5BK ideal for long-term industrial use.
The feed-through terminal design allows direct conductor-to-conductor electrical continuity, making it suitable for control circuits, signal wiring, machine panels, automation systems, and compact junction box installations. Instead of using loop wiring methods, the AS2.5BK provides a clean and secure conductor termination point inside industrial electrical cabinets.
Manufactured using high-quality polyamide insulated housing, the AS2.5BK provides excellent dielectric strength, heat resistance, and mechanical durability. The insulated body improves operator safety by reducing accidental contact risks and ensures reliable long service life in demanding industrial environments.
The terminal block supports conductor sizes from 0.34 mm² to 2.5 mm² stranded wire and up to 4 mm² solid conductors, with a rated voltage of 800V and current rating of 24A, making it suitable for industrial signal circuits, machine wiring, automation systems, and compact electrical distribution applications.
Its DIN rail mounting compatibility (DIN 35 / DIN 35-15) ensures quick installation in industrial control cabinets and modular electrical panels. The compact angular profile makes it an excellent choice for space-constrained wiring systems where neat cable routing is important.
The AS2.5BK is widely used in:
With its angular wire entry, spring clamp technology, black circuit identification colour, and compact feed-through design, the AS2.5BK is a practical and reliable terminal block solution for professional industrial electrical installations.
