Common potential matrix patchboard, 726 Series, operating tool Our common potential matrix patchboard (item number 726-661) is designed for seamless electrical installations. Conductors should only be connected to this common potential matrix patchboard if their strip length is between 16 and 17 mm . Featuring conductor terminals along with Push-in CAGE CLAMP® as well as CAGE CLAMP®, this connector outperforms the competition. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, boasting a key feature: It allows direct insertion of both solid and fine-stranded conductors with ferrules without needing tools. No preparation is required; for example, crimping the conductor's ferrule is not necessary. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all conductor types without having to prepare the conductor. For example, you don't need to crimp ferrules. The dimensions are (34.6 x 132 x 80.7) mm (width x height x depth). This common potential matrix patchboard is suitable for conductor cross sections ranging from 0.2 mm² to 16 mm² on one side and for conductor cross sections ranging from 0.08 mm² to 2.5 mm² on the other side.
