Advantages

This connector stands out due to its superior IP68 protection rating, which guarantees complete resistance to dust ingress and protection against prolonged immersion in water. The versatile design accommodates a wide range of wire cross-sections from 0.5 to 2.5 mm², providing flexibility for different electrical projects. Its high electrical capacity, supporting up to 24A and 450V, ensures it can handle demanding power requirements safely and efficiently. The inclusion of adjustable cable glands allows for a secure fit for cable diameters between 5–9 mm and 9–12 mm, ensuring a tight seal that prevents moisture from entering the connection point.

Suitable for

• Outdoor lighting installations
• Industrial electrical wiring
• Underwater electrical connections
• Garden and landscape power distribution
• Submersible pump power supply

When it may not be suitable

This connector is not intended for use with high-voltage power lines exceeding 450V or for applications requiring specialized shielded cables that do not fit within the specified diameter range. It is also not suitable for environments involving extreme chemical exposure that could degrade the housing material.

Key specifications

• Number of pins: 3
• Rated current: 24A
• Rated voltage: 450V
• Wire cross-section: 0.5–2.5 mm²
• Cable diameter range: 5–9 mm or 9–12 mm
• Protection rating: IP68

How to use

To use the NORDEL NLHC203T, first ensure the power supply is disconnected. Strip the insulation from your wires to the appropriate length and insert them into the terminal block, securing them firmly with the provided screws. Once the wires are connected, slide the cable through the sealing glands and tighten the outer caps securely to compress the internal seals around the cable jacket. Ensure all components are aligned correctly before final tightening to maintain the hermetic seal.

What to consider before purchase

• Verify that your cable diameter falls within the 5–12 mm range.
• Ensure your electrical load does not exceed the 24A or 450V limits.
• Check that the wire cross-section is between 0.5 and 2.5 mm².
• Confirm the environment requires an IP68-rated waterproof connection.

Usage recommendations: Always inspect the rubber seals for debris or damage before assembly to ensure the IP68 rating is fully maintained. Periodically check the tightness of the cable glands after installation to ensure the seal remains secure over time.
