Main line branch terminals (HLAK)

Main line branch terminals:
Cost efficiency, simplicity and safety

Main line branch terminals are the first choice for connecting mains supply conductors. HORA eTec components are also suitable for use in other application areas, such as junction boxes. Main line branch terminals feature an optimized design, with the HORA eTec range covering both A and part-safe B designs as well as C designs that are finger-safe on all sides. These last designs have since come to dominate the field in electrical engineering solutions.

Main line branch terminals in optimised design

HORA eTec main line branch terminals benefit from huge savings in costs due to the optimized design in the brass body, and simplified screw mounting cuts installation times. Dome technology keeps screws attached to the plastic casing, preventing loss. No brake screws are needed, eliminating torque loss during installation. The rounded edges ensure a user-friendly design.

The plastic casings are self-extinguishing and halogen-free. Identical design in every 25 mm² and 35 mm² main line branch terminal ensures free stacking and combination arrangements. All main line branch terminals can be horizontally and, in most cases, vertically mounted on TS 35 rails according to IEC 60715 / DIN EN 50022. The mature technology used is suitable for voltages up to 1.000V AC or DC.

Main line branch terminals in various designs

Our range covers the following C versions:

  • 25 mm² main branch terminal: single pole, single or double block; three, four or five poles
  • 35 mm² main branch terminal: single pole, single or double block; three, four or five poles
  • 70 mm² main branch terminal: single pole

The entire main line branch terminal range has been certified and approved according to IEC, VDE, UL, CSA and FI. All versions have also been subjected to independent power-loss testing at SGS Fimko. All C-versions of the HORA eTec main line branch terminals are approved for round or sector-shaped solid, stranded and flexible conductors in copper or aluminium; a specialised triple coating on the brass body makes this possible.

25 mm² version available in MCB width

HORA eTec main line branch terminals are currently the narrowest on the market. The module width of 17.8 mm on 25 mm² main branch terminals saves lots of space and therefore huge costs. HORA eTec will optionally custom-label your main line branch terminals with your customer brand on request. Delivery in custom industrial packaging is also available. All main line branch terminals fulfil the EC Directive on the Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS). Covers in the respective live, neutral, and earth colours are available.

Apart from the C-type models, HORA eTec supplies non-finger-proof A-type and the vertically finger-proof B-type main line branch terminals, each available in 25 mm², 35 mm²/25 mm² and 35 mm² versions. All the non-finger-safe main line branch terminals are available in single, double, four and five-pole versions.
