Cable for potentially explosive atmospheres OZ-BL 25x1 mm² blue, black numbered cores acc. to DIN VDE 0293-334 14018

Cable for hazardous areas – safety and flexibility in intrinsically safe installations

This blue OZ-BL cable, with a cross-section of 1 mm² and 25 cores, is specifically designed for use in areas at risk of explosion. It meets the requirements of DIN VDE 0285-525-2-51 / DIN EN 50525-2-51 standards, guaranteeing its reliability and safety in harsh industrial conditions. This cable is ideal for applications where flexibility and resistance to medium mechanical stress are required, while maintaining protection against sparking.

The cable is characterized by high-quality workmanship – the copper cores are stranded and flexible (class 5), which facilitates installation and ensures durable connections. PVC insulation (type Z 7225) and an external coating of the same material provide good protection against external factors. The cores are black and marked with white numbers according to DIN VDE 0293-334, which simplifies the identification of individual wires in the installation.

Key features and applications

The OZ-BL cable is not only safety but also practical solutions for installers and users:

• Application: Ideal for control and measurement systems in hazardous areas (type -i-), where protection against sparking is required.
• Flexibility: The construction with stranded cores ensures easy routing of cables even in tight spaces.
• Temperature range: It can be used in a wide temperature range – from -40°C to +80°C during permanent installation and from -15°C to +80°C during assembly.
• Rated voltage: Designed to operate at 300/500 V AC.
• Resistance: It has a fire reaction class of Eca according to EN 13501-6, which increases safety.
• Durability: The cable is resistant to UV radiation and weather conditions, allowing it to be used in outdoor installations as well.
• Identification: Core marking with numbers facilitates correct cable connection.
• Outer diameter: The approximate outer diameter is 15.4 mm, which should be taken into account when choosing appropriate connectors and accessories.

This cable is not suitable for laying in the ground, so it should be used as intended – indoors or in places protected from direct contact with the soil. It is a reliable solution for professionals who value safety, quality and ease of installation.
