STAUBLI 23.0480-21
The STAUBLI 23.0480-21 is a fork-lug adapter for fixed installation, used when creating a secure connection to, for example, screw terminals. It is made of brass and constructed to be an integral part of the installation instead of a loose transition.
At one end, there is a Ø 4 mm rigid socket in an insulating encapsulation, which accommodates spring-loaded Ø 4 mm plugs with a rigid insulating sleeve. This makes it suitable when working with standardized 4 mm connections and needing a fixed transition in the installation.
The fork-lug part can be bent once up to 90°. This provides some flexibility during installation when space or angle in the system requires it. The electrical contact surface is nickel-plated, while the contact's base material is CuZn, i.e., brass.
The stated ratings are 1000 V, CAT II, and 20 A. This makes it easy to see what electrical level the adapter is intended for in the specific setup.
