Knife-disconnect terminal block, nom. voltage: 500 V, nominal current: 28 A, 1 level, connection method: Push-in connection, Rated cross section: 4 mm2, cross section: 0.2 mm2 - 6 mm2, 2nd level, connection method: Push-in connection, Rated cross section: 4 mm2, cross section: 0.2 mm2 - 6 mm2, mounting: NS 35/7,5, NS 35/15, color: gray
- The Push-in connection terminal blocks are characterized by the system features of the CLIPLINE complete system and by easy and tool-free wiring of conductors with ferrules or solid conductors
- The compact design and front connection enable wiring in a confined space
- In addition to the testing option in the double function shaft, all terminal blocks provide an additional test pick-off
PTTB
The Phoenix Contact PTTB Series comprises double-level terminal blocks that utilize Push-in connection technology, designed to optimize wiring efficiency and space utilization in industrial applications. These terminal blocks are engineered to provide reliable and maintenance-free connections, making them suitable for various control and automation systems.
Key Features:
Double-Level Design: The PTTB Series features a double-level configuration, allowing for higher wiring density by accommodating two separate potentials within a single terminal block. This design conserves space in control cabinets and facilitates organized wiring layouts.
Push-in Connection Technology: Employing Phoenix Contact's Push-in technology, these terminal blocks enable tool-free and secure insertion of solid conductors or conductors with ferrules. This connection method reduces installation time and ensures a reliable contact.
Compact Form Factor: With widths as narrow as 5.2 mm, the PTTB terminal blocks are designed to maximize space efficiency without compromising performance.
High Electrical Ratings: Depending on the specific model, the PTTB Series supports nominal voltages up to 500 V and nominal currents up to 28 A, accommodating a wide range of industrial electrical requirements.
Versatile Conductor Compatibility: These terminal blocks support a range of conductor sizes, typically from 0.14 mm² to 6 mm², providing flexibility for various wiring applications.
