Board fit and routing
The 398800404: The 35° (145°) board-angle orientation is the dominant layout constraint — it places the wire-entry axis above the PCB plane, which affects wire routing geometry in enclosed panels and dictates how much vertical clearance the enclosure must provide above the board. Through-hole legs pin the block to the board at the standard Eurostyle footprint; verify that your drill/via pattern matches before committing the layout.
What this class is for
Eurostyle 39880 terminal blocks are used as wire-to-board power interconnects in industrial automation, PLC I/O modules, motor drives, and power supplies — anywhere a discrete conductor must land on a PCB under field wiring without soldering. The 300 V rating covers single-phase industrial control circuits; the 17.5 A per circuit handles most low-to-medium power distribution roles within that envelope.
What to check before you commit
The 398800404 is a single-level block — confirm your circuit count is exactly four or that your panel design accommodates the 4-position module in a daisy-chained bank of multiple blocks. The screw torque spec of 0.79 Nm is the clamping limit; over-torquing the M3 screw risks deforming the cage spring, which is the most common field failure mode on rising-cage clamps under vibration. Re-torque confirmation is a standard pre-commissioning step in industrial panel builds.
