The spring technology is particularely adapted for severe environment conditions such as vibration, chocks (presses, looms, etc...). Further more, the front access and the wiring ergonomy of the blocks are bringing much more flexibility of wiring in many situations where accessibility is difficult.
The ABB Entrelec range is particuliarely extensive and can meet all type of applications. A large number of functions is available from standard feed-through blocks to sensos-actuators, switch and fuse blocks.
The jumpering system offers much flexibility of use with 2 jumper locations on the blocks (possibility to make alternate, successive jumpering or to jumper two blocks of different size), and offers the same performances in terms of vibration than the spring connection. This jumper is then combining safety of use and fast mounting. A test point is available on most blocks for a quick and easy test of the wiring.
