OMY 3x1 300/300V black is a three-core flexible power cable with a conductor cross-section of 1.0 mm², intended for low-voltage electrical connections up to 300/300 V. The cable features PVC insulation around each conductor and an outer PVC sheath that gives basic mechanical protection and electrical insulation. Its compact construction and flexibility make it suitable for internal wiring, appliance connections and fixed installations where a slim, pliable supply conductor is needed.
Advantages
The cable combines a small conductor cross-section with three insulated cores, allowing space-efficient routing and reliable low-voltage power distribution. PVC insulation and outer sheath offer resistance to abrasion and provide basic protection against moisture and chemical exposure typical in indoor environments. Its flexibility facilitates installation in conduits, trunking and tight spaces without special tools.
Suitable for
- Internal household wiring and branch circuits
- Connection of small appliances and equipment requiring up to 300/300 V
- Fixed installations in residential and commercial buildings
- Routing through conduit, cable trays and surface-mounted channels
When it may not be suitable
This cable is not designed for use in exposed outdoor installations where prolonged UV exposure, direct sunlight or severe weather conditions occur, and it is not rated for direct burial in ground. It is also unsuitable for applications requiring high-temperature resistance, halogen-free materials or enhanced fire performance beyond basic PVC properties.
Key specifications
- Number of cores: 3 (three conductors)
- Conductor cross-section: 1.0 mm²
- Rated voltage: up to 300/300 V
- Insulation material: PVC around each conductor
- Outer sheath material: PVC
- Colour: black
- Flexibility: flexible type suitable for routing in confined spaces
How to use
Strip the outer sheath and individual conductor insulation the appropriate length for the intended terminals or connectors, taking care not to nick conductor strands. Connect the conductors to the corresponding terminals following local wiring colour conventions and electrical codes. Secure the cable with appropriate clamps or supports to avoid mechanical strain at termination points. For fixed installations, run the cable through suitable conduit, trunking or cable channels and ensure it is protected from sharp edges and heat sources.
What to consider before purchase
- Confirm that the 1.0 mm² conductor cross-section and 300/300 V rating meet the current-carrying and voltage requirements of your application.
- Verify that PVC insulation and sheath properties (temperature range, flame behaviour) are acceptable for the installation environment.
- Check local electrical regulations for required cable types and installation practices.
- Measure cable runs and allow extra length for terminations and routing.
Usage recommendations
For safe and code-compliant installations, use correct terminal crimping or screw connections, protect the cable from mechanical damage with conduit or trunking where needed, and follow local electrical standards. When in doubt about suitability for a specific load or environment, consult a qualified electrician.
