PT and PTTB Pluggable Push In DIN Rail Terminal Blocks
Description
Push-in wiring with a pluggable interface
PT2.5/1P provides one level and one electrical potential. PTTB2.5/2P provides two levels and two independent potentials. Each level combines a fixed push-in wire connection with a pluggable contact interface. Both models mount on NS35/7.5 DIN rail.
