Silicone measuring leads PP BM 10A, CAT IV 1000V, BL21S2-T4SC 105051

Safety and Flexibility in High-Voltage Measurements

Silicone-insulated test leads are a solution that combines high-temperature resistance with excellent flexibility, which is crucial when working in tight switchboards or when access to measurement points is difficult. The model designated CAT IV 1000V has been designed for environments with the highest risk of overvoltages, such as main power distribution boards or connection installations. This allows users to safely perform measurements not only in domestic installations but also in industrial settings where voltage can reach 1000 V. Silicone insulation not only protects against electric shock but also prevents material cracking even at low temperatures or with frequent bending, thereby extending the set's lifespan compared to standard vinyl cables.

Application and Connection Versatility

The set includes test probes equipped with Ø2 mm tips, which are the standard for most digital multimeters. Importantly for professionals performing diverse tasks, an additional screw-on shroud with a diameter of Ø4 mm is also included. This construction allows for quick adaptation of the leads to different types of multimeter sockets without the need to purchase separate accessories. These leads are ideal for:

• Voltage and current measurements in industrial circuits (up to 10A).
• Diagnostics of electrical installations in public buildings.
• Work in conditions requiring high-level safety (CAT IV category).

Thanks to the classic "banana" plug connection, attaching and detaching the leads from the meter is quick and secure, speeding up on-site work.

Key Construction Features and Operating Parameters

The construction of the leads has been designed to withstand harsh operating conditions. Silicone insulation provides chemical and mechanical resistance while allowing cables to be routed freely around sharp edges without risk of abrasion. The maximum working current is 10A, which is sufficient for most voltage measurements and short-term load current measurements. Safety certificates confirm compliance with standards for the CAT IV 1000V category, meaning the leads have been tested for resistance to overvoltages originating from the distribution network (e.g., from lightning strikes or network short circuits).

The insulation material is flexible, temperature-resistant silicone, and the terminal construction includes 2 mm probes with the option to mount a screw-on 4 mm shroud. The entire set carries a CE certificate confirming safety and compliance with the WEEE directive regarding the disposal of electrical equipment. These leads are designed for use with digital multimeters and offer a high level of protection in challenging environmental conditions.

By choosing this model, you receive a set proven in demanding working conditions that minimizes the risk of measurement errors resulting from poor-quality cabling or insulation damage. It is a solid choice for every electrician who values safety and tool durability.
