Thomas & Betts Aluminum Two-Port Solid Pin Terminal Center, Tan

Two versions are made: the APA-2 for No. 2 conductor and the APA-4 for No. 4. Pick the model by the conductor you are landing, since the solid pin and ports are sized to that gauge rather than adjustable across a range.

No. The APA-2 is a solid pin power terminal center, a lug-type aluminum connector for landing large service conductors, not a control-wiring block. For DIN rail feed-through control terminals you want something like the ABB ZS4-T3 screw clamp terminal block or the Eaton XBT XB Series feed-through block instead.

No, they solve different problems. The APA-2 is an aluminum two-port solid pin terminal center rated 600V, sold under the Blackburn sub-brand, and it is a cable or wire lug type device used to terminate heavy conductors. The ABB ZS4-T3 is a feed-through screw clamp terminal block in the 1SNK5 series, a control-panel style block. Use the APA for pin-terminating a No.2 or No.4 aluminum or copper conductor, and the ZS4-T3 where small-gauge wiring is being carried through a rail-mounted block.

The Blackburn APA aluminum solid pin terminal center is rated 600V. For a higher-voltage feed-through, the Eaton XBUT-4 is an XB Series IEC terminal block rated 800V wide feed through, and the Square D GV1G09 is a TeSys GV2 top feed terminal block rated 3-pole 63A/690V for TeSys D and TeSys U starters. Note that both of those are panel-wiring blocks rather than aluminum pin lugs, so confirm the conductor you are terminating suits the style before substituting.

Yes, the Blackburn APA aluminum terminal center carries a 600V rating, which covers normal service entrance and panel work on 120/240 and 277/480 systems.

The APA-4 body is aluminum, and Blackburn aluminum connectors of this type are dual rated AL9CU unless marked otherwise, so verify the AL9CU marking stamped on the body before landing copper. The aluminum construction itself is confirmed.

Country of origin is the United States, which is what a government or institutional buyer working to a domestic-content requirement needs on the submittal.

It is a two-port center, so each unit takes two conductors of the rated size. Need more taps than that and you will have to install additional units; they are sold individually, not in multi-packs.

Not for that. The APA aluminum terminal center is a 600V two-port conductor lug. For feeding a motor starter you want a purpose-built power block such as the Square D TeSys GV2 top feed terminal block, which is a 3-pole 63A/690V block for TeSys D and TeSys U starters.

Order the Eaton 10250TA62 for that application - it is a 30.5mm heavy-duty pushbutton terminal block in the 10250T series, built to mate with 30.5mm operator hardware. The Blackburn APA-2 is an aluminum two-port solid pin terminal center for terminating a No.2 conductor and has no relationship to 30.5mm pushbutton mounting.

The Blackburn APA two-port solid pin terminal center is the aluminum one - aluminum construction, tan, rated 600V and carrying UL E63167, offered for No.2 and No.4 conductors. The comparable Eaton XBUT-4, Eaton 10250TA62, ABB ZS4-T3 and Square D GV1G09 are IEC and control-style terminal blocks rather than aluminum conductor lugs, so if the spec on the drawing calls for an aluminum pin terminal the APA is the one to match.

The tan color is how Blackburn identifies this port size in the APA terminal center line, so on a panel with several sizes installed you can tell the No. 2 and No. 4 centers apart from neighbouring sizes at a glance.
