Overview
The Insta terminals incorporate up to 3 different terminal func-
tions in one enclosure of 6.2 mm width. Only two terminals are
required to set up a complete three-phase outgoing line (L
1
, L
2
,
L
3
, PE/ground, N), and each phase can be bridged and multi-
plied by the 3 cross connection links. The dimensions comply
with the requirements for mounting distribution boards in public
buildings. The neutral busbar has a different height to the neutral
isolating terminals; the 16 mm² 8WA2 011–3JG11 or 8WA2 846
feeder terminal is used for the infeed.
PE, L, NT Insta terminal
The 8WA2 011-3JG10 terminal is the basic version for AC cir-
cuits. It comprises:
• Protective conductor connection
• Through-type connection for one phase conductor (L
1
)
• Neutral conductor connection which can be isolated from the
10 mm × 3 mm neutral busbar by means of a slide.
A complete three-phase outgoing line requires an additional
8WA2 011-3JG12 (L
2
, L
3
) terminal. The three-phase feeder can
be multiplied by means of the linking system described below.
PE, L, N Insta terminals
If no neutral isolation is required, the 8WA2 011-3JG17 terminal
is used:
• Protective conductor connection
• Through-type connection for one phase conductor
• Through-type connection for the neutral conductor
PE, L, L Insta terminal
The design of the 8WA2 011-3JG16 terminal is similar to that of
the 8WA2 011-3JG17 terminal; instead of a through-type con-
nection for the neutral conductor, a through-type connection for
a second phase conductor has been provided.
L, L Insta terminal
The 8WA2 011-3JG15 and 8WA2 011-3JG18 terminals respec-
tively include one and two through-type connections for phase
conductors.
