Terminals with Spring-Loaded Connection
8WH isolating blade terminals
■ Overview
Through-type terminals with isolating blade capability are the
most commonly used terminal types in instrumentation and
control.
Key features of these isolating blade terminals with a nominal
cross-section of 2.5 mm² are their narrow width of only 5.2 mm
and their high current carrying capacity of 16 A. In addition, the
terminals provide a test pick-off parallel to the isolating point for
2.3-mm ∅ test plugs. Potential distributors can be conveniently
built with connecting combs.
Terminals with three and four clamping points are available for
multi-conductor connection. With their compact design these
terminals can also be used in small terminal boxes and their front
connection arrangement enables user-friendly wiring.
The isolating blade is secured to the terminal so that it cannot be
lost.
