Barrier Blocks terminal strips are widely used for many applications in various industries and arenas, especially in the electrical or electronics industry for interconnection of various components. The SEFCX-1 is a type of Barrier Block which offers solid performance and durability in most applications.

Introduction

The SEFCX-1 Barrier Block from Siemens is designed for wiring and interconnecting a variety of electrical components with a maximum wire current of 14A. The 6 mm spacing between the feed-through of the terminal offers a larger number of connections per block allowing more advantageous wiring and connections. The SEFCX-1 is UL listed and CSA certified to UL498, 60898-1, and C22.2 No.14 standards. This ensures a high quality product, certified for use in a variety of governmental, industrial and consumer applications.

Design and Construction

The SEFCX-1 Barrier Block utilizes a strong polyamide terminal body with a black finish. It brings together 30 screws with close pitch location which makes the terminal block very rigorous and stiff. The terminal blocks terminal is surrounded by a V-shaped plastic bar, and the inserted screw is made of brass. It is widely used for panel and DIN rail mountable enclosures due to its high strength and excellent electrical insulation. The integrated integrated snap-on adapter with Click & Safe feature is designed to ensure correct assembly and allow wire entry with a single-hole knockout.

Working Principle

The working principle of the SEFCX-1 Barrier Block involves the connection of electrical components such as wires and terminals to its feed-through connection points, with the wires passing through a hole drilled in the barrier block body. This terminal block provides a secure connection of two or more wires with the required current rating by the interconnection holes and the screw head of the terminal block. The unique design of this terminal block ensures that all the wires are well secured and insulated against any risk of electric shock. This terminal block is also equipped with a patented Easy-Installation feature which allows the user to quickly add, remove, or replace the connectors without tools.

Applications

The SEFCX-1 Barrier Block can be used in a variety of industrial and domestic applications. It is suitable for junction boxes, control panels, electrical enclosures, etc. Further, this terminal block is also used in telecom systems, fire and security systems, automotive and electronic equipment, audio/video equipment, power supplies, solar energy systems, switch cabinet and junction box manufacturing, etc.

Advantages and Benefits

The SEFCX-1 Barrier Block offers several advantages in most applications. It is designed with a push-in connection angled terminal strip which reduces overall height of the junction box and material costs due to its small footprint. The terminal block ensures better heat dissipation and electrical insulation due to its V-shaped plastic bar design. It requires just one hole for the placement of the screws which reduces time-consuming labor during set-up and installation. The terminal block is also UL-listed and CSA-certified, and is suitable for use in industries with strict safety standards.
