Phoenix Contact Double-Level Terminal Block, 26 to 12AWG, 500V Maximum Voltage - PTTB 2.5 BU - 3210570


This double-level terminal block from Phoenix Contact is a safe and easy way to connect wires in a circuit where space is tight. With four connections spread over two levels, it takes up less room than a single-level alternative so is ideal for organising a crowded control cabinet. The two levels are offset to give easy access to both, even when the terminal block is fully wired. You'll find units like this used in the railway industry, machine building or process manufacturing.
As part of the PT series, this product uses Phoenix Contact’s innovative CLIPLINE complete system. This makes it bridgeable with other multi-conductor and function terminals and lets you put together a fully customised terminal block system. A straightforward push-in connection method and lateral conductor entry make wiring quick and easy, even in confined spaces.

• ATEX certification guarantees safety in environments with a potentially explosive atmosphere
• Plug-in connection method uses 50% less insertion force to reduce conductor wear
• Flame-retardant polyamide housing offers protection from fire and electrical hazards for maximum safety
