What is a fuse terminal block?
In some applications it is useful to protect the feed through connection with a separate fuse. Fuse terminal blocks are made up of one terminal block bottom section with a fuse insertion carrier. The fuses vary from pivoting fuse levers and pluggable fuse holders to screwable closures and flat plug-in fuses.
What is disconnect terminal block?
Basic disconnect terminal blocks. Basic disconnect terminal blocks provide a uniform, universal disconnect zone, where various plugs for components, fuses, isolating plugs, and feed-through connectors can be used.
What is the use of terminal blocks?
Terminal blocks are used to secure and/or terminate wires and, in their simplest form, consist of several individual terminals arranged in a long strip. Terminals are useful for connecting wiring to a ground or, in the case of electrical power, for connecting electrical switches and outlets to the mains.
What is a knife disconnect?
Knife Disconnects Knife disconnect terminal blocks are used when a circuit needs to open in a control system without disturbing the wiring. Knife disconnect terminals – also known as wire disconnects – have a compact design that makes installation in small spaces easier.
How do you select a terminal block?
Electrical specifications The most important specification to consider when selecting a terminal block is its current rating. The three specific areas that should be considered are the conductivity of the terminals, the cross-sectional area, and the corresponding temperature rise.
Are terminal blocks connected?
Terminal blocks are available as rows, but each terminal connects to only a single wire. The most common connection method for terminal blocks is the use of a screw, wherein wires are inserted and then clamped down with the use of a single screw.
Do I need a terminal block?
Terminal blocks increase safety by grounding, isolating, and protecting the other components in the electrical circuit. Terminal blocks are available with finger-safe connections to prevent electrical shock. And, terminal blocks can also provide test points, which add even more safety to the circuit.
Why choose WDTR test-disconnect terminal blocks?
However, their use requires sufficient current protection and a reliable disconnection circuit. Our WDTR test-disconnect terminal blocks enable a safe and simple electrical isolation in confined spaces. Two potentials can be operated with only one terminal block, resulting in space-savings of 50%.
What is Weidmüller WSI 25?
The new Weidmüller WSI 25 10X85 1.5KV fuse terminal blocks protect components in 1,500 V systems from overvoltage. WSI 25 10X85 1.5KV fuse terminal blocks support operating voltages of 1,500 V and have a particularly reliable contact protection. To replace the fuse, the entire fuse holder including the fuse can be removed.
What is the Weidmüller configurator?
IN the Weidmüller Configurator (WMC) you can digitally plan, assemble, and directly order complete terminal rails – including accessories. You can also create complete parts lists and installation instructions for production. In this way, failures can be avoided and costs can be saved.
Why use A2t test-disconnect terminal blocks?
However, their use requires sufficient current protection and a reliable disconnection circuit. Our A2T 2.5 DT/DT test-disconnect terminal blocks enable a safe and simple electrical isolation in confined spaces. Two potentials can be operated with only one terminal block, resulting in space-savings of 50%.
