The Terminal Blocks B 310 and B 318, with capacity for up to 100 pairs, have been developed for outside plant conductors and they offer protection against voltage and current surges when equipped with the MP 5 pins electrical protection modules from Bargoa. These blocks use the “wire wrap” technology and can be supplied with or without a previously connected cable. The B318 Block has a more compact format than the B310 due to the absence of the testing area.
