EGIS™ 4 Circuit 30 Amp Screw Terminal Block. Screw terminal connection pairs provide one input and one output screw connected to separate copper alloy bus bars for each matching connecting pair. Includes compatible jumpers for bridging circuits as needed. 125 Volt AC or DC Rated easily supports 12, 24, 36, and 48 VDC systems, as well as 120/240 Vac applications (ensure implementation meets applicable accessibility standards as applicable). Marine grade materials ensure long lasting reliability in harsh environment applications. Tin plated copper alloy conductors, stainless steel hardware, and high temperature insulation materials deliver a robust solution.
