Screw-on attachment
Screw-on attachment is implemented in the case of sizes S00 and S0 by
means of push-in lugs (see Section 2.4 for information on circuit-breaker
accessories).
In the case of sizes S2 and S3, the holes for screw-on attachment are inte-
grated in the mandatory rail adapter.
The following illustration shows screw-on attachment by means of push-in
lugs in the case of the fuseless load feeder of frame size S00:.

Important
In the case of screw-on attachment without a rail adapter, the feeder must
not be screwed onto a conductive surface. Insulation is necessary so that, in
the event of a short circuit of the circuit breaker, there is no short circuit to
the base plate.
