What the ratings mean for the fit
The 0399700104: Tin-plated copper contacts and nickel-plated brass clamp are standard for industrial power bus terminations. The PBT housing sets the 130 °C continuous ceiling; above that the clamp torque and contact normal force both degrade. Horizontal orientation places wire entry perpendicular to the PCB.
Where Eurostyle 39970 fits
The Eurostyle 39970 series is used as a board-level power distribution block in industrial control panels and machine tool wiring — the heavy pitch and current rating make it a permanent termination point for field-run power conductors on the PCB side of the harness. The through-hole soldertails anchor the block mechanically during thermal cycling, which matters in panels that see repeated thermal excursions.
Sourcing and lifecycle
The 0399700104 is Active and ROHS3 Compliant. Sourced to order against the BOM quantity — confirm the 4-position count against the circuit count before committing. No official successor order code is on record.
