## Long description

PHOENIX-CONTACT PT 2,5-QUATTRO BU is a light-blue feed-through terminal block designed for conductor cross-sections from 0.14 to 2.5 mm². Intended for DIN-rail mounting in control cabinets, it offers a compact solution for secure electrical connection and insulation of signal and power wiring. The quad terminal arrangement allows space-efficient multi-wire termination while maintaining clear conductor separation and reliable contact integrity.
Advantages
The terminal block supports a wide conductor range, enabling connection of fine-stranded and solid conductors within the same device. Its compact QUATTRO design reduces required DIN-rail space compared with multiple single terminals while preserving individual circuit isolation. The light-blue color provides visual distinction for identification in wiring layouts. The robust construction and proven screw connection method ensure consistent contact pressure and long-term electrical continuity in control cabinet environments.
Suitable for
DIN-rail mounted control cabinets in industrial automation
Electrical distribution and machine wiring with multi-conductor terminations
Signal wiring and low-power circuits requiring clear separation of conductors
Panel wiring where space-saving quad terminals improve layout density
Key specifications
Conductor cross-section range: 0.14–2.5 mm²
Terminal type: feed-through, quad arrangement
Mounting: DIN-rail
Connection method: screw connection for secure clamping
Color: light blue for visual identification
How to use
Mount the terminal block on a standard DIN rail and tighten the mounting clip according to the rail specification. Strip conductors to the recommended length for the clamp type, insert each conductor into its respective terminal point and tighten the screw to the torque recommended for the conductor range to ensure reliable contact without damaging the conductor. Observe correct polarity and routing when terminating signal and power wires, and keep design documentation updated to reflect the quad terminal assignments.
Usage recommendations
Use appropriate wire ferrules for fine-stranded conductors to improve contact reliability. Regularly inspect screw torque in maintenance intervals and follow applicable electrical standards for conductor sizing and insulation. Avoid exceeding the specified conductor cross-section range and ensure correct labeling to maintain clear circuit identification.
