PCB terminal block, nominal current: 20 A, rated voltage (III/2): 630 V, nominal cross section: 2.5
mm2, number of potentials: 1, number of rows: 1, number of positions per row: 1, product range:
GKDS-EX, pitch: 7.5 mm, connection method: Screw connection with tension sleeve, screw
head form: L Slotted, mounting: Wave soldering, conductor/PCB connection direction: 0 °, color:
black, Pin layout: Linear pinning, Solder pin [P]: 5 mm, number of solder pins per potential: 2,
type of packaging: packed in cardboard. The article can be aligned to create different nos. of
positions! Every group of terminal blocks is to be provided with a GRZ 2,5V-EX (1706112) flange
plate on both sides. If there are more than 10 terminal blocks, at least one additional flange plate
must be mounted for each further group of ten. When the pitch spacer GRZ 2,5-EX (1724628) is
used, the max. working voltage is increased to 420 V.

Your advantages
• Well-known connection principle allows worldwide use
• Low temperature rise, thanks to maximum contact force
• Satisfies the more stringent safety requirements of “Ex e” protection according to IEC 60079-7 for potentially explosive areas
• Quick and convenient testing using integrated test option
• Two solder pins reduce the mechanical strain on the soldering spots
• The latching on the side enables various numbers of positions to be combined
