The M3 screw applies the clamp force at a specified torque of 0.68 Nm (6 Lb-In), which sets the contact resistance and pull-out repeatability for field wiring. The black polyamide (nylon) housing carries a 300 V rating and accepts a 13.5 A per-position load — the current limit is set by the wire gauge and the ambient temperature inside the enclosure, not the terminal block itself. ## Wiring the rising cage clamp The rising cage clamp captures the stripped wire between the nickel-plated copper clamp and the conductor path. The M3 screw, also nickel-plated copper alloy, drives the clamp upward — the wire is not wrapped around the screw. Strip length should match the clamp depth; the datasheet drawing gives the insertion depth. The side interlocking feature lets multiple 0398900304 blocks snap together side-by-side to build a multi-pole strip on a common PCB footprint, sharing the 5.00 mm pitch across all positions.","metaTitle":"Molex Eurostyle 0398900304, 4-Position 5.00mm Terminal Block","metaDescription":"Molex 0398900304 Eurostyle terminal block, 4 positions, 5.00mm pitch, 13.5 A, 300 V, rising cage clamp, M3 screw.
