Ergom Wire Ferrule H 4 x 15mm ERHN 100 Pieces

The Ergom Wire Ferrule H 4 x 15mm ERHN is an essential electrical accessory supplied in a convenient set of 100 pieces, designed specifically for professional wiring, control panels, and industrial maintenance applications. These insulated wire ferrules ensure secure and reliable termination of flexible stranded copper conductors in electrical installations. By neatly enclosing the wire strands, the ferrule effectively prevents strand fraying and guarantees optimal connection quality when used with both screw and spring-clamp terminals.

Advantages

Using these insulated wire ferrules significantly improves the reliability and safety of electrical connections in various setups. The durable plastic insulation provides added protection at the termination point, while the high-conductivity metal tube ensures efficient electrical performance. The design facilitates quick and correct insertion into terminal blocks, reducing installation time and minimizing the risk of loose strands causing short circuits. This pack of 100 pieces ensures an adequate supply for ongoing maintenance projects and systematic control panel wiring.

Suitable for

• Terminating flexible stranded copper conductors
• Wiring electrical control panels and distribution boards
• Industrial maintenance and repair work
• Connecting wires in screw and spring-clamp terminals
• Professional electrical installations

When it may not be suitable

This product is not designed for use with solid copper or aluminum conductors, as wire ferrules are specifically engineered for stranded wire. Additionally, it is unsuitable for wire sizes that do not match the H 4 x 15mm specification, as incorrect sizing can lead to loose connections or installation failure.

Key specifications

• Brand: Ergom
• Model: ERHN
• Ferrule type: Insulated wire ferrule
• Conductor size compatibility: 4 mm²
• Pin length: 15 mm
• Quantity per package: 100 pieces

How to use

To use the Ergom wire ferrule properly, strip the insulation from the flexible copper conductor to match the required length of the metal tube. Carefully gather all the fine strands of the wire to ensure none are left outside, and insert the stripped conductor fully into the metal barrel of the ferrule. Place the insulated collar and metal end into a suitable crimping tool designed for wire ferrules and apply sufficient pressure to secure the connection firmly. Once crimped, the terminated wire can be safely inserted into the screw or spring-clamp terminal and tightened according to standard electrical practices.

What to consider before purchase

• Verify that your conductor cross-section matches the 4 mm² size requirement
• Check that the 15 mm pin length is compatible with your specific terminal depth
• Ensure you have a correct crimping tool suitable for this ferrule size
• Confirm whether insulated ferrules meet the requirements of your specific application

Always use the correct crimping tool designed for wire ferrules to ensure a mechanically secure and electrically sound connection. Turn off all power sources before performing any electrical installation or maintenance work.
