Safe and reliable material: These automatic connection terminals are composed of insulating and flame retardant materials. The clamps are resistant to corrosion, aging and reusable. Inner conductor material is nickel-plated copper, has a good high conductivity. and reliable. Easy to use: No tools are necessary.nut first 9 to 10 mm cable sheath, lift the lever up to 90 , insert the wire, then press the lever. Each clip has a test hole, an electric pen can be used to check if the terminal is powered.This makes it convenient for testing and maintenance. Universal connectors: These connection terminal are adapted. For solid and twisted conductors of 0.08 to 2.5 mm and the flexible conductors of 0.08 to 4 mm.2 holes, 3 holes, 5 holes meet different types, which is very convenient, meet your needs different. of large applications: These compact connection terminal are ideal for the construction of cables connected in parallel. They can be used in the house and workshop. Ideal for lighting systems, construction cables, communication systems and security alert systems. The packet contains: these set of wire connectors have total 60 pliers , 20 2-way clips, 30 3-way clamps, 10 5-way clamps. Specifications: Material: Nylon Pa6.6 Flame retardant insulating materials Indoor conductor material: nickel-plated copper Nominal voltage: 250 V Nominal overvoltage voltage: 4 kV Nominal current: 32a Cross section (solid conductors and strands): 0.08 - 2.5 mm Cross section (flexible conductors): 0.08 - 4 mm Length of the band: 9 - 10 mm Large application: these compact connection terminal are ideal for the construction of cables connected in parallel.Perfait for the house, the workshop, the lighting systems, the construction cables, Communication systems and security alert systems. How to use: 1. Distribute the 9 -10 mm cable sheath. 2. Lift the lever at 90 . 3. Insert the wires. 4. Push the lever down to close the pliers. Safety tips: 1. Cut the power supply before installation so that the cables are turned off. 2. Since the copper spring is very elastic, it must be avoided that it does not attract your fingers when opening and closing the orange lever switch. 3.Seck clipper Connection terminals Has a test hole, an electric pen can be used to check if the terminal is powered.This that makes it convenient for tests and maintenance. the Set of connection terminals includes: 20 2 hole pliers (PCT-212: 2.1 x 1.3 x 1.5 cm) 30 3 hole pliers (PCT-213: 2.1 x 1.7 x 1.5 cm) 10 5 hole pliers (PCT-215: 2.1 x 2.7 x 1.5 cm)
