High-Performance Terminal Blocks Save Time, Space

Phoenix Contact’s SPT 5 pc board terminal blocks provide fast wiring of conductors for power applications in a compact form factor. These terminal blocks use a fixed, one-piece printed-circuit terminal block with a spring-cage wire termination design. A zigzag pin design allows for an unrestricted 600-V and 35-A UL capability, with a pitch of 7.5 mm. The stackable design enables any combination of position sizes, and both right-angle and vertical-pc-board-mount versions are available.

Solid conductors and stranded conductors with ferrules can be applied without the use of tools; the conductor is simply pushed into the spring-cage connection. For stranded wires without ferrules, a screwdriver is placed into the actuation shaft to open the contact termination point. The screwdriver remains in the actuation shaft during wire placement to allow “two-handed wiring” by the installer. The result is reduced labor costs and reliable wire terminations.
