Phoenix Contact 3211430 PTTB 2.5-2DIO/O-UL/UR-UL Series Grey, 0.14 → 4mm², Double-Level, Push In Termination

Using the diode terminal blocks of the PT push-in connection terminal blocks makes it possible to solve a variety of switching tasks. The diode is integrated either from left to right or vice versa in the terminal housings. Three and four-conductor terminal blocks are also available for multi-conductor connections.

Integrated diodes (1N 4007) and lamps on certain parts
Push-In technology with 50 % less insertion force for direct plugging from 0.34 mm²
Configurations include lamp test circuits and fault message circuits

This double-level feed-through terminal block from Phoenix Contact is an easy way to safely connect wires in a circuit. It features a robust polyamide insulator to protect your equipment from short circuits and current surges. An additional level of security against electrical incidents comes with the integration of blocking diodes to prevent reverse currents or resistance. This makes the unit suited to demanding industrial use, especially in current and voltage limitation and distribution applications.
The block benefits from push-in connection technology for easy, tool-free wiring and a secure contact between conductors. It can handle wire gauges from 26 to 12AWG, giving you a high degree of flexibility over input and output wiring. Because it uses Phoenix Contact’s innovative CLIPLINE complete system, it can be connected easily to other terminals, allowing you to customise the system to your needs.

• Flame-retardant thermoplastic housing offers protection against fire hazards
• DIN rail-mounted for easy installation
• Plug-in connection method uses 50% less insertion force, reducing wear and tear on conductors
• CSA, cUL, UL and GOST certification guarantees it meets the highest international safety standards

Push-In Connection Terminal Blocks

The PT series is characterised by easy, direct conductor connection, and it consistently uses the advantages of the CLIPLINE complete system. The up to 50% lower insertion forces of the PT push-in connection method also allows easy and direct plugging of solid and stranded conductors with ferrules of 0.34mm² and up.
