Eurostyle 39910 Terminal Block — 2-Position, 60 A Power Distribution Point
The Wieland Electric 399100102 is a 2-position, single-level terminal block from the Eurostyle 39910 series, designed for through-hole PCB mounting with horizontal (side-entry) wire orientation. It carries a 60 A current rating and a 600 V voltage rating — bus-level power for a two-circuit distribution point, not a signal line. The 0.400" (10.16 mm) pitch gives the creepage distance needed for that 600 V rating without forcing an oversized board footprint, and the M4 screw with a 1.36 Nm (12 Lb-In) torque spec means you can cinch down 6 AWG wire without stripping the clamp.
Termination and Wiring — Rising Cage Clamp for 6-18 AWG
Wire termination is screw-rising cage clamp — the screw lifts a brass-nickel plated clamp plate against the conductor, capturing the full cross-section without cold flow. The clamp material is brass with nickel plating, the screw itself is bronze with tin plating, and the contact is copper with tin plating. Accepts 6-18 AWG stranded or solid wire; the M4 thread gives enough clamping force for the heavy 6 AWG cable that matches the 60 A rating. The torque spec of 1.36 Nm (12 Lb-In) is a field-service number — over-torque strips the clamp, under-torque lets the wire back out under thermal cycling.
This is a board-level power interconnect for industrial control cabinets, motor drives, power supplies, and distribution panels. The 60 A / 600 V rating puts it in the main DC rail or AC line input position, not a signal bus. Through-hole mounting gives the mechanical strength to handle the M4 screw torque without tearing PCB pads — surface mount would not survive the first field termination.
No official successor or cross-reference is on record — this is the current production part for the 2-position, 10.16 mm pitch, 60 A position in the Eurostyle 39910 series.
