The clamping yoke, tension clamp, insulation displacement
and the PUSH terminal block system offer increased
protection against accidental loosening and have been
designed such manner that the ends flexible wire
conductors need preparation. According 60079-0 modular
terminals for explosive conditions are so-called explosion-
proof components.26 1282250000 2012/2013
