Hager K28N 4-napainen pääjohdon liitinrima 25/4x16 mm² harmaa

The Hager K28N main line terminal block provides a robust 4-pole connection point for distributing power from a 25 mm² main conductor to four 16 mm² branch conductors. Its compact grey polyamide housing and screw terminals suit DIN rail or screw mounting in distribution boards.

Highlights

• 4-pole design for three-phase and neutral distribution
• Accepts 1 x 25 mm² main input and 4 x 16 mm² branch outputs
• Rated for 100 A and 690 V AC
• DIN rail (TS35) or screw mounting
• Brass screw terminals with 3.5 Nm (main) and 2.5 Nm (branch) tightening torque
• Polyamide housing, IP20, UL94-V0 flammability rating

In daily use

Install the K28N in a distribution board to create a tidy and safe junction for main supply lines. The screw terminals accept rigid or flexible conductors, and the clear labelling helps identify each pole. The grey housing blends with standard electrical enclosures.
