High Current Terminal Blocks
Terminal blocks for high electrical current are specialized terminal blocks necessary to make terminations in circuits carrying high current and high energy. They are found in a variety of industrial and commercial settings, including wind turbines, power distribution systems, and electric vehicles. High current terminal blocks are usually constructed from sturdy, vibration-resistant materials, using reliable screw connection methods. They are intended to occupy as little space as possible while accommodating large wires and serving as an electrically safe pathway to other components.
High current terminal blocks are flexible and can be used with a great variety of conductor types and sizes. The terminal block assembly technology can secure and reliably connect three types of conductors: rigid, stranded, and flexible. Some terminal block designs even allow for up to four conductors to connect at a single point, reducing the number of terminal points required, and thereby saving space and cost.
FAQs
What type of connection technology do pluggable terminal blocks use?
Pluggable terminal blocks use screw connection or spring connection technology, allowing quick and secure plug-in wiring for flexible installations and easy maintenance.
Do high current terminal blocks come with direct mounting options for use with DIN rail or a mounting plate?
Yes, high current terminal blocks are available with direct mounting options, allowing installation on either a DIN rail or a mounting plate for flexible applications.
Do test plugs allow for flexible conductors, rigid conductors and stranded conductors with a variety of conductor cross section ranges?
Yes, test plugs are designed to work with flexible conductors, rigid conductors, and stranded conductors across a wide variety of cross section ranges for versatile testing.
Terminal Block Basics
Single Level Pass Through Terminal Blocks are used to connect two wires together with a common junction point. This is helpful when a component needs to be disconnected or isolated within a circuit. These are the most common types of terminal blocks in industrial applications.
Ground Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: they are grounded. These terminal blocks have a metal connection from where the wire is terminated, all the way to the bottom of the block where it will clamp into the panel. This allows for an electrical circuit to be grounded without running a wire to the main ground connection on a breaker or surge protector.
Fused Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: the presence of a fuse. This fuse provides protection for components from too much voltage or current.
Multilevel Terminal Blocks are used to connect two wires together with a common junction point, just like single pass though terminal blocks, but with the advantage of making two electrical connections in the same block. These blocks also incorporate fuses and can be grounded.
Disconnect Terminal Blocks are similar to fused blocks, however the disconnect stops the flow of electricity by lifting a lever on the terminal block. Unlike fuse blocks, they are a more permanent solution, but will not provide any protection in the event of a power surge.
