<p>The termination rail has a number of knife blade contact elements supported by a pair of insulating blocks (3,4) arranged at an angle to one another, so that the knife blade contacts form two rows of relatively angled terminal strips (1,2), e.g. at 90 degrees to one another. One of the insulating blocks has ratchet elements (5) allowing it to be secured to a mounting frame in 2 alternate positions, via corresponding ratchet openings. The mounting frame may be fitted with a dust cover for protecting the knife clamp contacts.</p> |
