Terminal blocks are components used for connecting and consolidating electrical wires and cables, making it easier to manage the electrical circuitry in an application. The ATB35R from Phoenix Contact is a 35mm installation height power terminal block designed to provide a high level of insulation between power circuits.

Overview

The ATB35R is a 3.5kV power terminal block with 900V conduction insulation and features twin wiring on opposing sides. It supports a connection capacity of 1-4 AWG conductor cross section with an 8 mm² wire braid, and is designed as a small base terminal block to provide enhanced wiring. The ATB35R is also highly resistant to chemicals, which makes it suitable for a wide variety of industries, such as:

• Automotive
• Aerospace
• Medical
• Industrial controls
• Food and beverage

The ATB35R is available with either the standard aluminum or stainless steel housings, and is an ideal choice for the continuous operation up to 100A.The terminal blocks are available in a variety of colors to make it easier to find the right connection for the application, making it easy to identify circuits quickly.

Design and Mounting

The ATB35R terminal block can be mounted on a variety of standard and customized Din Rail chassis, including the Phoenix Contact style U19, U25, and U32, and has a current rating of up to 95 A.For easier installation during aftermarket repairs or upgrades, the terminal blocks also feature removable locks, enabling the easy removal of a section of wiring without cutting or exposing any additional wiring.

The terminal blocks also feature integrated push-in connections, which significantly reduce the wiring time and costs associated with installation. This helps to reduce overall installation complexity while also eliminating the need for tedious and costly soldering or rustproofing processes.

Working Principle

The ATB35R power terminal block achieves its high level of insulation through a two-level braid system that provides superior grounding and insulation on both sides of the connection. The first level of the braid, known as the terminal connection, consists of a crimped stainless steel sleeve that fits around the terminal with a locking connection, helping to prevent accidental disconnection of the wires. The second layer of the braid is a mesh-like sheet, which serves to make the connection watertight and seal off any exposed wiring.

The ATB35R terminal block is designed for use with any wiring system that requires a safe connection between power circuits in applications that require high voltage or electrical insulation. The terminal block is also designed for use in a wide variety of hazardous environments, making it suitable for use in a variety of industries.
