The Megger 100A-KC-R 100A Kelvin Clamp, Red, is designed for use with any electrical test instrument. The clamp connects to a multimeter using safety banana leads and built-in banana posts (hardware not included); alternatively, users can upgrade hard-wired lead sets (not included) by removing the dust cover to expose a 100A stud and flying potential lead. The expandable metal jaw provides unparalleled versatility, allowing for connection to any size test specimen. With a limited lifetime warranty, this shatterproof plastic clamp is built to last.
