Two versions are available:
• as entry feeder unit for 2 × 25 A, 30 A, 40 A and 2 × 40 A,
• as end feeder unit for 2 × 25 A, 30 A, 40 A and 2 × 40 A.
The scope of supply also includes 1 end flange for each respectively.
Cable entry from 3 sides; use cable gland made of plastic,
metric, with strain relief M25 or M32 (not included in the scope
of supply).
Tap-off plugs
Insulated tap-off plugs are used for taking current from the
tap-off points on the trunking units. They can be mounted and
removed by hand. This is even possible with live busbars.
The following are available:
• 3-pole and 5-pole versions without fuse base, with halogenfree,
flame-retardant cable.
• 3-pole and 5-pole versions without fuse base, with terminal
and M20 plastic cable grommets.
• 3-pole versions with fuse base for cylindrical fuses
8.5 mm × 31.5 mm; type gG (IEC) and type gL (VDE) quick,
with halogen-free, flame-retardant cable.
• 3-pole and 5-pole versions with fuse bases for 1 or 3 cylindrical
fuses 8.5 mm × 31.5 mm; type gG (IEC) and type gL
(VDE) quick, with terminal and M20 plastic cable grommets.

The phase pick-off is factory set for 5-pole tap-off plugs.
The phase assignment of the tap-off plugs is visible from the outside.
Cables of up to 2.5 mm 2 can be connected to tap-off plugs with
terminals. The connecting cables should be supported separately
if necessary.
