Phoenix Contact 3210923 PTTB 2.5-DIO/O-U 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

Use this terminal block from Phoenix Contact to make quick and secure connections between wiring and components in your equipment. It's designed to be mounted on a standard DIN rail, making for speedy installation and compatibility with common fittings.
The terminal block's push-in termination method lets you remove and rearrange your circuitry rapidly with no tooling required. This cuts down on maintenance and repair time and makes it easy to adapt or update your electrical system.
As it has a surge voltage rating of 6kV, this device will protect your equipment in case of over-voltage or short circuits, increasing workplace safety. The grey PA (polyamide) housing material offers excellent durability and strength, ensuring reliable performance over a long service life.
