<h2>Double potential terminal block, 279 Series, light gray</h2><br/><br/>This double potential terminal block (item number 279-989) provides hassle-free electrical installations. Conductors should only be connected to this double potential terminal block if their strip length is between 8 and 9 mm . Our double potential terminal blocks feature two independent potential current bars on one level to save space. Each side of the terminal block can be used to separately through-wire one potential. This product features conductor terminals and utilizes CAGE CLAMP®. Our renowned universal connection known as CAGE CLAMP® is the industry standard when it comes to connection technology and electrical interconnections. Depending on the conductor type, this double potential terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 1.5 mm².<br/><br/><h3></h3><br/><br/>This through rail-mount terminal block is operated with an operating tool.<br/>
