VOLTCRAFT MSS-140 Safety Test Probe Set 4 mm Socket CAT III 600 V Red/Black

Electricians and service technicians working on building installations, control cabinets, or industrial equipment often need reliable, safe test probes for measurements up to 600 V. The VOLTCRAFT MSS-140 safety test probe set delivers exactly that: two robust probes with 4 mm safety sockets, rated CAT III 600 V, and a practical length of 140 mm for comfortable handling. The set includes one red and one black probe, both with nickel-plated brass tips for excellent contact and a pointed tip design that penetrates oxidation or protective coatings on terminals and conductors.

Why choose it

These probes are built for daily professional use. The CAT III 600 V rating ensures safe measurements in fixed installations, such as distribution boards, circuit breakers, and industrial wiring. The 4 mm safety socket accepts standard shrouded test leads, preventing accidental contact with live parts. The nickel-plated brass tips offer low contact resistance and long-term durability, while the PVC insulation provides flexibility and protection against abrasion. The set includes both colours for easy polarity identification.

Ideal use cases

• Voltage and continuity testing in electrical panels
• Measurements on motors, transformers, and industrial controls
• Diagnostics in building installations and switchgear
• Laboratory and test bench applications

Good to know

The MSS-140 probes comply with IEC/EN 61010-031 and are compatible with all standard 4 mm safety test leads. Always verify that the connected test lead and measuring instrument meet the same or higher safety category. The pointed tips are ideal for reaching recessed contacts, but should be used with care to avoid damaging fine conductors.
