RS PRO Q Series Cross Connector for Terminal Block, Copper, 10 Pole, Natural, 800V, 20A, Screw Mount 399-105

RS PRO 399-105 Q Series Cross Connector is a high-performance accessory engineered to provide reliable electrical cross-connections in DIN rail terminal blocks. This model features a robust copper material with a tin-plated surface, maximizing electrical conductivity and corrosion resistance over extended use in demanding industrial environments.

Offering 10 poles, the connector is preassembled for rapid deployment. Users can cut it down to the required length, allowing flexibility for varied installation requirements. Screws and collars are removable to accommodate skip-over terminals, making the cross connector suitable for both consecutive and non-consecutive terminal block connections.

The screw mounting type employs M2.5 slotted screw heads, supporting secure installation. Its compact width of 49.9 mm and length of 4 mm fit easily into panels where space is limited. With a hole diameter of 2.8 mm, hole height of 2.5 mm, and pitch size of 5 mm, the connector is compatible with a wide range of terminal blocks.

Electrical ratings include a maximum voltage of 800 V (with partition) or 400 V (without partition), and a rated current of 20 A. The cross-sectional area of 2.5 mm² ensures adequate capacity for typical wiring requirements. A tightening torque range of 0.4 to 0.8 Nm provides a secure mechanical and electrical connection.

Elaborate contamination degree 3 rating ensures reliability in industrial conditions. The product supports easy adaptation in control cabinets, automation panels, power distribution systems, and manufacturing applications, where efficient bridging of terminal block circuits is essential.

RS PRO accessories maintain high standards for performance and durability, trusted worldwide in professional environments. This cross connector is an essential asset for installers, panel builders, and maintenance engineers requiring modular, safe electrical connectivity within complex assemblies.

Designed for efficient cross-connection in DIN rail terminal blocks. Supports flexible branching with up to 10 poles preassembled, cuttable as needed. Copper-tin plated for premium conductivity and corrosion protection. Rated for demanding conditions - 800 V max voltage (partitioned) and 20 A current.

Screw mounting with M2.5 threading provides reliable installation. Hole, pitch, and size dimensions match common industrial terminal block standards. Slotted screw heads and adjustable torque range facilitate safe, secure usage.
