tightening reliability: the reliability the connection (cable-lugs bars) guaranteed screw and nut clamping, with one flat and
one spring washer, having the function counteracting the effects high dynamic stress. Every insulating body, made thermoplastic material, manufactured two specular half-shells which fit into each other means centring pins. The conducting bar also manufactured with equivalent concave housing increase the clamping effectiveness the conductors. The side walls the half-shells are stiffened and box like; this not only improves the aesthetic aspect these large terminal blocks, but also guarantees improved stability and linearity the entire installation. mounting: due their large dimensions and they bear high strain caused the stress generated the conductors, new rail mounting system has been researched into and designed for them. the rails themselves are installed straight wall, the size GPM terminal blocks make the use flat rail supports indispensable that the terminals can adequately distanced from the surface. The spring reaction the pressing force the conductor works block under the head the tightening screw, avoiding unloosening, even presence vibrations.cabur

The different versions, obviously, have different but always innovative and original solutions the problem guaranteeing the IPXXB protection degree. Even when the cross-connection place, the assembled terminal board provided with these accessories guarantees IPXXB protection degree, without the need any further cover. cross-connection: with this series products also possible create cross connection between two three adjoining terminal blocks using the appropriate jumper. For each terminal block, /FIX version for the direct panel-mount available. addition, the contact surfaces both the pressure plate and the concave housing the conducting busbar are provided, their whole length, with cross grooving which improves the connection characteristics. marking: identification both sides can made all the terminal blocks GPM series, despite the size, with either CNU/8 type elements) CSC (up elements) marking tags. warning protection: all the versions are contained particularly articulated insulating bodies which guarantee IPXXB degree protection, without the need any further accessory. The mechanical retention the conductors guarantees low resistance the resulting electrical contact. this way, access can guaranteed into the connection unit and for all the cable lugs bars for tightening and loosening operations, protection for the “cable” versions: this case the protection fixed and has click insertion. orthogonal the axis the terminal block and protects the wire clamping collar, the pressure plate and the tightening screw. fact appropriate seats inside the side walls the half-shells the following may inserted:
• protection for the “bar” versions: this protection, which normal installation conditions longitudinal position respect the
axis the terminal block, can easily rotated with the simple aid screwdriver (as mentioned the safety regulations).

This type protection provided with “sliding gate” device, which vertical the terminal block protection and line with the conductors insertion hole; allows, with manual action with the best safety conditions, close partially totally the hole itself and protect the live parts, when using conductors having cross-section much lower than the rated one when wiring the terminal block only one side.
