The 387217302: Top termination uses screws with a captive plate — the plate stays captured in the screw, so it does not fall out during wiring. This is a field-friendly detail for panel builders: strip the wire, insert under the plate, torque the screw. Bottom termination is a 0.187" quick-connect tab, insulated, for pre-made female spade terminals. This dual-termination style means the block can serve as a field-wiring point (top screws) while the bottom connects to a pre-assembled harness or bus bar via push-on terminals. The terminal screw is steel with a zinc, trivalent finish, and the screw finish is corrosion-resistant for long-term reliability.
Mounting and Compliance
Chassis or panel mount with the flange — two screws through the flanges hold the block in place. The block is ROHS3 compliant, covering the current EU restriction of hazardous substances directive. The terminal screw finish is zinc, trivalent, a hexavalent-chrome-free process that meets modern environmental requirements.
