The document introduces the ERTD series disconnect terminals, including their electrical ratings and connection data. The terminals are available for different types of conductors and feature a screw connection for secure connections. The terminals are made of polyamide 6.6 material and have high insulation performance. They are suitable for 500V voltage and 24A current, and are compatible with conductor cross-sections ranging from 4mm2 to 10mm2.
The ERTD series disconnect terminals from IMO allow circuit interruption without removing conductors, using a removable busbar that can be replaced with a fuse. The ERTD4 model disconnects by lifting a knife‑type contact, providing easy operation for devices with utility instruments and transformers.
The document lists electrical ratings, insulation stripping lengths, connection options, mounting rail dimensions and ordering codes for the ERTD2, ERTD3, ERTD3M and ERTD4 variants, with both English and Italian descriptions.
