B&K Precision TL37 test leads

These leads connect any multimeter, clamp meter or test instrument that accepts a standard shrouded banana plug. The set includes one red and one black lead, each three feet long. They are intended for technicians and engineers who need reliable, safety-rated connections for everyday electrical measurements.

Safety ratings and current capacity

The leads are rated CAT II 1000 V without the protective cap, CAT III 1000 V and CAT IV 600 V with the cap fitted. Maximum current is 10 A, giving headroom for typical bench and field work. Without the cap the higher CAT III and CAT IV ratings are not available, so the leads cannot be used at those levels in higher-energy environments.

Thermals and power draw

As passive test leads they generate no heat and draw no power of their own. The only thermal consideration is the 10 A current limit, which should not be exceeded during normal use. Noise is not a factor because there are no active components.

Questions about this item

Will the 0.16 in shrouded banana plugs fit the older bench meter I still use?

The right-angle shrouded banana plugs are standard 0.16 in diameter, so they mate with any meter, clamp meter or test instrument that accepts a standard shrouded banana plug.

How can I confirm the CAT III 1000 V rating is active after I connect the leads?

The CAT III 1000 V and CAT IV 600 V ratings apply only when the protective caps are installed; with caps removed the rating drops to CAT II 1000 V.

Are the two 3 ft red and black leads the only items in the package, or do I need to order caps separately?

The package includes two 3 ft test leads, one red and one black, with the protective caps already fitted for the higher CAT III and CAT IV ratings.
