Electrical cable OMY 3x0.75 300/300V black — 3 conductors 0.75 mm², 300/300 V

OMY 3x0.75 300/300V is a compact three-conductor electrical cable with each conductor having a 0.75 mm² cross-section and a black outer jacket. It is intended for low-voltage power distribution and connections where a flexible, small-diameter three-core cable is required. Typical applications include wiring of small appliances, indoor lighting fixtures, audio/video equipment and control circuits where rated voltage up to 300/300 V is sufficient.

Advantages

The cable combines a flexible conductor design with a slim outer jacket that facilitates routing through conduits, cable trays and tight installation spaces. With three insulated cores, it enables simple and tidy connections for live, neutral and earth or for signal and power combinations depending on the application. The black jacket provides a neutral appearance for visible installations and offers basic mechanical protection for everyday indoor environments.

Suitable for

• Indoor low-voltage power distribution for small appliances and fixtures
• Connecting lighting fixtures and LED installations where a compact three-core cable is needed
• Wiring for audio/video devices and home entertainment systems
• Control circuits and signal wiring in machinery or building automation (within rated voltage)

When it may not be suitable

This cable is designed for low-voltage, indoor use and is not intended for direct burial, outdoor long-term exposure, or installations that require special resistance to oils, chemicals or high mechanical stress. It is also not suitable for circuits that demand larger conductor cross-sections for higher current capacity or for installations that require specific fire-resistance or halogen-free properties unless those are confirmed separately.

Key specifications

• Number of conductors: 3
• Conductor cross-section: 0.75 mm² per conductor
• Rated voltage: 300/300 V
• Outer jacket colour: black
• Design: flexible multi-core cable suitable for routing in conduits and trays

How to use

Strip the outer jacket and individual conductor insulation carefully to expose the conductors. Connect the conductors according to the circuit requirements—typically live, neutral and earth or the appropriate signal/power assignment—using suitable terminals or connectors rated for the conductor size. Ensure all connections are secure and that the cable is supported and routed to avoid sharp bends or mechanical damage. Follow local electrical codes and safety practices, including correct overcurrent protection and grounding where required.

What to consider before purchase

• Confirm the conductor cross-section (0.75 mm²) is adequate for the intended current load and circuit protection
• Verify that the 300/300 V rating matches the installation voltage and local regulations
• Check suitability for indoor use; not specified for direct burial or prolonged outdoor exposure
• Determine whether additional properties (fire resistance, halogen-free, oil resistance) are required for your project

Usage recommendations

Use this cable for short runs and internal wiring where a flexible three-core solution is needed; avoid tight bending radii and protect the cable from mechanical damage. For higher currents or specialized environments, select a cable with a larger conductor cross-section or certificated environmental resistances.
