RUKO STB-8376-M3-m-180° 3-Conductor Lever-Actuated Terminal Block, Transparent Housing with Orange Levers

The RUKO GMBH STB-8376-M3-m-180° is a lever-actuated terminal block with three conductors, designed for secure and tool-free wiring in power distribution applications. Unlike screw-type terminals, its CAGE CLAMP® mechanism provides vibration-resistant connections and fast installation without special tools.

Highlights

• Lever-actuated CAGE CLAMP® connection for quick, maintenance-free wiring
• Supports solid, stranded, and fine-stranded copper conductors from 0.14 to 4 mm² (24–12 AWG)
• Rated for up to 450 V and 32 A, suitable for demanding electrical installations
• Transparent polycarbonate housing with orange levers for easy visual inspection and operation
• Compact design for free wiring in junction boxes, control cabinets, and distribution boards

In daily use

Electricians and panel builders benefit from the clear strip length marking of 11 mm and the colour-coded levers that indicate open or closed positions. The terminal block accommodates a wide range of conductor types, making it versatile for both solid building wire and fine-stranded flexible cables. The transparent housing allows a quick check of the connection status without disassembly.
