June 19, 2016 – CONTA-CLIP introduced the PushIn terminal series PRK. The range is designed to provide users with a number of design improvements on conventional PushIn terminals and satisfy demanding requirements regarding ease of use and mechanical stability. The PushIn connection ensures a safe insertion of rigid wires or wires with end sleeves.
For a quick release of inserted wires, the terminals are equipped with a pusher that requires slight pressure and no special tools, although the PushIn-springs provide high contact force for the wire connections. Accidental incorrect insertions of wires are made impossible due to the physical separation of the insertion channel and pusher. The internal layout with large contact surfaces and fixed metal parts ensures a high current-carrying capacity with low heat build-up, mechanical toughness and an absolutely secure hold of the compact terminals. All potentials have a test point for measurement.
PRK range feed-through and PE terminals are available for six nominal cross-sections from 1.5 mm² to 16 mm² in versions with two, three and four-wire connectors suitable for wire cross section from 0.34 mm2 to 25 mm2. The protective-conductor terminals are equipped with a foot contact on both sides to ensure electrical and mechanical reliability.
In addition, CONTA-CLIP offers the plug-in cross-connection system PQI for potential distribution. Standard terminals with rated cross-sections from 1.5 mm2 to 10 mm2 can route two potentials within the two cross-connection channels. All insulating materials used in the PRK series are free of harmful substances and meet the V-0 self-extinguishing fire classification according to UL 94.
