What the key ratings mean for the fit
The 398800504: The 5.08 mm pitch and 2-position count define the board footprint — match this against the circuit count in the harness BOM before committing. At 13.5 A per circuit the block sits in the low-to-mid power range; the copper-tin contact plating is standard for industrial signal and control wiring rather than high-cycle field mating. The interlocking feature on the side allows multi-pole assemblies to gang together — useful when panel layouts need a wider bus bar built from discrete blocks rather than a single multi-position part. Operating range is -40°C to 105°C with a PA/nylon housing; the M3 screw clamps with a brass-nickel plated clamp body and bronze-nickel screw, which handles the torque requirement without corrosion concern in panel environments. The 0.68 Nm torque figure is the setting to dial on the assembly driver — under-torque risks high resistance at the clamp, over-torque risks cracking the housing on insertion.
Sourcing and compliance
Production status is Active and the part carries ROHS3 Compliant designation. Quoted to order against BOM quantity — confirm lead time for volume requirements. No official successor or cross-reference order code is listed for this MPN.
