Phoenix 3248126 MPT 2,5 BU Mini Feed-Through Terminal Block, Screw Connection, Blue

In control cabinets and junction boxes, space is always at a premium, and traditional terminal blocks often consume more room than necessary. The Phoenix 3248126 MPT 2,5 BU mini feed-through terminal block solves this by offering a compact, high-density solution for connecting two conductors in a single position. Its screw connection ensures a secure, vibration-resistant joint, while the blue housing provides clear visual identification in complex wiring setups.

Who is it for

This terminal block is ideal for panel builders, machine manufacturers, and electrical installers who need reliable wire termination in confined spaces. It suits applications in industrial control systems, building automation, and any project where DIN rail space is limited but performance cannot be compromised.

Main features

• Miniature design saves valuable rail space without sacrificing current capacity.
• Screw connection with M3 thread accepts solid conductors up to 4 mm² and flexible up to 2.5 mm².
• Rated for 500 V and 24 A, making it suitable for a wide range of power and signal circuits.
• Polyamide (PA) insulating body with UL 94 V0 flammability rating ensures safety.
• Wide operating temperature range from -60 °C to 105 °C for harsh environments.
• Supports direct mounting or DIN rail installation with an adapter for flexible integration.

Tips

When installing, ensure the conductor is stripped to exactly 8 mm to achieve optimal contact and prevent strand breakage. Use a torque screwdriver set to 0.5–0.6 Nm to avoid damaging the terminal or causing loose connections. For DIN rail mounting, pair with the appropriate Phoenix adapter to maintain proper alignment and spacing.
