Part Number:	ULO	-	TB365	-	USLKG10N
Explanation:	Brand		Series Code TB365 - USLKG10N TB363 - USLKG16N; this ordering breakdown covers these two models only		PE Terminal Model USLKG10N - TB365; 10mm² nominal cross-section USLKG16N - TB363; 16mm² nominal cross-section; both are green/yellow PE terminals

Description

Protective-earth connections on a DIN rail

USLKG terminal blocks provide two screw connections at one level and a metal grounding foot for the protective-earth connection to the rail. Green/yellow insulation identifies the PE function. The two conductor connections share one potential; the central rail-clamp screw is not an additional conductor connection.
