Blackburn ASR7525 SPLICE REDUCER SLD BARRIER 250-750

The ASR7525 is a compression splice reducer for wire or cable, used to join two different conductor sizes in the 250 to 750 range. It has an internal barrier, so each conductor seats on its own side of the splice and bottoms out where it should instead of being pushed past center during crimping.

Yes. The ASR7525 is a dual-rated connector, made of aluminum with a tin plated surface, which is the standard construction for AL/CU rated compression connectors. That means it can terminate aluminum or copper conductors, including a copper-to-aluminum transition splice.

A straight splice has one continuous bore, so a smaller conductor can slide past the midpoint and leave the larger side short on crimp length. The ASR7525 has a solid barrier between the two bores and stepped sizes covering 250 through 750, so each conductor stops at the correct depth and each side gets its full set of compressions. Use it wherever you are reducing from one cable size to another; use a straight splice only when both conductors are the same size.

It does. Tin plating over the aluminum body is what keeps the dissimilar-metal contact from setting up galvanic corrosion at the copper interface, which is why this style of connector is accepted for AL/CU work rather than aluminum-only.

It is a compression connector, not a mechanical setscrew lug, so it needs a hydraulic crimper with the die series the connector is marked for. Dies, crimping tool, and any insulating cover or tape for the finished splice are separate items and are not included with the connector.

It ships as a single piece, sold each, under manufacturer part number ASR7525. Order one per splice you are making.

The ASR7525 splice reducer is made in Mexico. Worth noting if you are working a job with country-of-origin documentation requirements on submittals.
