The Klein Tools CL150 is a True RMS AC flexible clamp meter with an 18-inch jaw that reaches into tight panels and around large cable bundles to measure up to 3000A. Rated CAT IV 600V / CAT III 1000V, it auto-ranges on all functions and features a backlit 3000-count LCD. Auto power-off engages after 15 minutes. Built to withstand 6.6-foot drops. This tool is designed for electricians needing access to high-current conductors in congested panels, switchgear, or conduit installations where a standard rigid jaw cannot fit. Powered by 2 AAA batteries. Covered by Klein Tools' 1-year limited warranty.
Is the CL150 still available?
No — the CL150 has been discontinued. There is no current Klein Tools flexible clamp meter in the active lineup with an equivalent 3000A range.
What made the CL150 unique?
The CL150 used an 18-inch flexible Rogowski-style clamp, allowing it to wrap around large conductors, bundled cables, and busbar configurations that a rigid jaw cannot access. Its 3000A True RMS capacity made it suitable for main service and industrial high-current measurements.
What current model is closest?
The CL910 (2000A, rigid 2.0-inch jaw) is the highest-capacity active Klein clamp meter but uses a fixed hook jaw. For large-conductor flexible-clamp work, third-party flexible Rogowski clamp adapters are the common workaround.
