Phoenix Contact PTN 2,5 N-scheidingsklem, Push-in, blauw, 2,5 mm², 500 V, 24 A

For installations where safe isolation of the neutral conductor is non-negotiable, the Phoenix Contact PTN 2,5 N-disconnect terminal block delivers a compact, tool-free solution. Its push-in connection technology accepts solid and flexible conductors without ferrules, cutting wiring time by up to 50% compared to screw terminals. The integrated knife disconnect allows the neutral path to be opened with a standard screwdriver, enabling quick testing and fault isolation without removing any wiring.

Highlights

• Push-in connection: direct insertion of solid conductors and flexible conductors with ferrules
• N-conductor knife disconnect for safe isolation and testing
• Rated cross section 2.5 mm², supports up to 4 mm² solid
• 500 V rated voltage and 24 A rated current (IEC)
• Blue housing for clear identification as neutral conductor terminal
• Mounts on standard DIN rail NS 35/7,5 or NS 35/15
• Flammability rating UL 94 V0, operating temperature -60 °C to 105 °C

In daily use

The PTN 2,5 excels in control cabinets and distribution boards where neutral disconnection is required for maintenance or safety checks. Its slim 5.2 mm width saves rail space, while the transparent cover over the disconnect point prevents accidental operation. The polyamide housing withstands harsh industrial environments, and the push-in design eliminates the risk of loose screw connections over time. Simply strip the conductor to 8–10 mm, insert, and the spring clamp holds it securely.
