Overview
The Insta or three-tier terminals incorporate up to 3 different ter-
minal functions in one insulating body of 6 mm width. The width
of 3 Insta terminals corresponds to the hole pitch of 18 mm stan-
dardized in distribution board assembly. Tools are required to re-
move the terminals from the support rail.
All clamping points for incoming and outgoing cables have a
notch for an 8WA8 8 labeling plate . The protective conductor
connections are already marked green-yellow and the neutral
conductor connections blue.
The neutral busbar has the same position for Insta terminals and
neutral isolating terminals. This allows, for example, the use of a
16 mm² neutral isolating terminal as an infeed for the neutral
busbar.
8WA1 011-3JF16, -3JF17 and -3JF18 allow the neutral busbar to
be routed with a mounting depth of 42.5 mm.

The 8WA1 011-3JF20 terminal is the basic version for AC cir-
cuits. It comprises:
• Protective conductor connection
• Through-type connection for one phase conductor
• Neutral conductor connection that can be isolated from the
6 mm × 6 mm neutral busbar.
PE/ground, L, N Insta terminals
If no neutral isolation is required, the 8WA1 011-3JF17 terminal
is used:
• Protective conductor connection
• Through-type connection for one phase conductor
• Through-type connection for the neutral conductor

Design of 8WA1 011-3JF16 terminal as previous version. Instead
of the through-type connection for the neutral conductor, a
through-type connection for a second phase conductor is fitted.

8AW1 011-3JF18 terminal contains two through-type connec-
tions for two phase conductors. These are generally used for
three-phase outgoing lines.
