Phoenix Contact Inc: Ring lug terminal blocks
The RT-series of ring lug terminal blocks, from Phoenix Contact, includes feed-through and ground terminal blocks for cables fitted with ring lugs in sizes from 1.5 mm through 35 mm.
Special terminal blocks are available for connecting current transformers in power supply applications. Hinged flaps and built-in cap nuts make the terminal blocks touch-safe after wiring. Cap nuts are held securely in position so that wiring is easy, even in cramped control cabinets. The terminal blocks have additional marking areas on each hinged cover, as well as on the top marking channel. The lower-priced RTO version comes without a hinged cover and captive nut--designed for applications where shock protection is not required.
