UL1953 PDB Open-Style 1000V 310A Adder 1 350-#6 in-6 #2-#14 out Box/Box
Product Description
The UL1953 Open-Style Power Distribution Block is designed for versatile applications, allowing for the safe installation and management of electrical circuits. This model, featuring an adder pole configuration, enables users to customize primary and secondary wire combinations efficiently.
Constructed to meet stringent safety standards, it is UL and CSA approved and complies with UL508A and the National Electrical Code®. The block supports a maximum operating temperature of 80 °C and is capable of managing a short circuit rating of up to 400 kA, ensuring robust performance under varying electrical conditions.
With a primary input that accommodates a wire range of 350-#6 and six secondary outputs capable of handling wire sizes from #2 to #14, this distribution block offers significant flexibility. Optional adder poles can be added without tools, enhancing ease of use in field applications.
The insulators are constructed from virtually unbreakable glass-filled polycarbonate, with optional hinged safety covers that provide additional shock resistance and ease of access for circuit testing. This block's design ensures effective spacing of 1 inch through air and 2 inches over surfaces between uninsulated live parts, fulfilling the requirements for feeder and branch circuits.
