Triple-deck terminal block, 2002 Series, operating tool Fault-free electrical installations are guaranteed with this triple-deck terminal block (item number 2002-3221/1000-413). Conductors can only be connected to this triple-deck terminal block if their strip length is between 10 and 12 mm . The triple-deck terminal block also serves as component terminal block with led. Featuring conductor terminals along with Push-in CAGE CLAMP®, this product is highly versatile. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, offering a key advantage: It allows direct insertion of both solid and fine-stranded conductors with ferrules without needing tools. No preparation is required; for example, crimping the conductor's ferrule is not necessary. Depending on the type of conductor, this triple-deck terminal block is ideal for conductor cross sections ranging from 0.25 mm² to 4 mm².
