This 1PC Heavy Duty 2Poles Double Throw DPDT 2P 100A Knife Blade Disconnect Switch is a rugged, manual disconnect switch designed to isolate two independent circuits with a single device. The DPDT (twopole, doublethrow) configuration provides flexible control, allowing each pole to switch between two outputs. With a 100A rating and knife blade terminals, it is built for demanding, current applications and offers quick, secure connections for maintenance or circuit selection. Key benefits Twopole, doublethrow DPDT operation for independent control of two circuits. current capability with a 100A rating, suitable for heavyload environments. Knife blade disconnect switch design with knife blade terminals for fast, secure connections and easy disconnection during service. Heavyduty construction intended for demanding applications and repeated operation. Packaged as a single unit (1PC), ready for integration into compatible systems. Key attributes Functionality: DPDT (twopole, doublethrow) knife blade disconnect switch. Compatibility: designed for twopole, doublethrow switching in current circuits.
