Phoenix Contact 1708378 PCB headers come with a nominal cross-section of 6mm², typically black in color and can handle up to 76A of current when used individually. When paired with the PC 6 plug, the combined current limit drops to 41A. Rated for a voltage of 1000V (Class III/II), these headers feature a silver contact surface and use a pin connection type. With four potential connections, they are mounted using wave soldering and have a linear pinning layout, with each pin spaced 5mm apart and having three solder pins per connection. They can be used in the COMBICON PC 16 plug-in system and do not require any locking mechanism or special packaging as they come pre-packaged in cardboard.
