Product details

Barrier Block for Panel Power Distribution

The 387600303: Rated 15 A per circuit at 300 V, with a dual-wall barrier between each terminal position. The dual-wall means there are two insulating ribs between adjacent circuits, not one — that extra wall reduces the chance of a wire strand bridging to the next terminal in a crowded panel or under vibration.

Flange Mount and Panel Fit

The flange feature on this block lets you bolt it directly to a chassis or panel — the mounting holes are integral to the thermoplastic body, so you don't need a separate bracket. For a field retrofit, that means you can drill a new hole pattern or reuse an existing one without reworking the whole assembly. The bottom termination is closed, so there is no through-hole pin or solder tail — all connections are made at the screw terminals on top.

Frequently asked questions

Will 387600303 drop into a panel specified around 387600306?

No — the 387600303 is a 3-circuit block, while the 387600306 is a 6-circuit block. The pitch, current rating, voltage rating, and flange mount are identical, but the panel cutout and mounting hole spacing scale with circuit count. A panel drilled for the 6-circuit block will have extra mounting positions and a longer opening than the 3-circuit block requires.

What compliance documentation is available for 387600303?

The block is ROHS3 compliant and the insulation carries a UL94 V-0 flammability rating. Full compliance documentation is provided with the order.

Where can I buy the 387600303 and how is it quoted?

The 387600303 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock-holding claim is made here.
