Push-in knife disconnect terminal from Phoenix Contact’s PTTB range. Two connection levels, two separate potentials — suits plant engineering panels where in-circuit disconnection is needed without pulling conductors.

Knife disconnect lets you isolate circuits cleanly. Both levels use push-in connection; no screwdriver needed for conductor insertion on direct plug-in sizes.
