The Sefram SP 295 and SP 296 AC current clamps measure up to 3000 A, offering CAT IV 600 V / CAT III 1000 V safety and flexible sensor lengths for tight spaces.
The SP 295 and SP 296 are flexible AC current clamps designed for industrial maintenance and failure diagnostics. They can measure currents from 30 A up to 3000 A and connect to any device with an AC voltage input, making them suitable for cramped environments where conventional clamps are impractical.
The clamps feature a TRMS accuracy of ±3 % full‑scale, a bandwidth of 45 Hz–500 Hz, and output voltages of 100 mV/A, 10 mV/A or 1 mV/A. They are powered by two 1.5 V AAA batteries, include a low‑battery LED indicator, and meet IEC 1010 safety ratings CAT IV 600 V and CAT III 1000 V. Dimensions, sensor lengths and loop diameters differ between the SP 295 and SP 296 models. This manual is written in French.
