AMtec Releases New UL1741-Listed Disconnecting Combiner Boxes


AMtec Solar Products, a unit of AMtec Industries, has unveiled its new Prominence Series configurable disconnecting combiner boxes, which feature disconnect ratings of up to 400 A at 1,500 V.

The company says the boxes are ETL listed to UL1741 at 1,500 V and CAN/CSA C22.2 listed at 1,500 V, and they are fully customizable with 275 A, 325 A or 400 A disconnects and up to 36 strings. Enclosures are available in NEMA 4 steel, NEMA 4X fiberglass or stainless, or 3R.

AMtec offers a range of additional configuration options, including single- or dual-hole output lugs, pre-configured pigtails, voltage monitoring, surge protection, string-level current monitoring, cable connectors and fuse ratings.

Tom Willis, AMtec’s director of sales, says, “The next generation of PV projects are already demonstrating that 1,500 V is really the new sweet spot.”

“These heavy-duty, high-capacity components allow us to continue to offer improved cost savings for our customers by reducing the number of overall components needed,” says Willis, adding, “the ETL listing to UL1741 provides a high level of assurance to our solar balance-of-system customers that these units meet the high standards of manufacturing quality that is characteristic of UL1741.”
