RT18-125
A cutout fuse for electrical distribution systems, designed to protect circuits from overcurrent. It fits into standard cutout fuse holders and is used in outdoor or indoor distribution panels where a simple, reliable fuse solution is needed. The product is suitable for general electrical distribution and protection applications in residential, commercial and light industrial settings.
- Provides circuit protection against overcurrent in distribution panels
- Designed to fit standard cutout fuse holders, ensuring compatibility with existing installations
- Simple and reliable operation for routine electrical protection
- Suitable for use in both indoor and outdoor electrical distribution systems
- Supports straightforward replacement and maintenance in field or panel environments
Where It Is Used
- Protecting low-voltage distribution circuits in outdoor electrical panels
- Replacing blown fuses in industrial control panels or switchgear
- Maintaining electrical safety in commercial building distribution systems
- Field repairs where a quick and standard fuse replacement is required
- Panel builders integrating standard protection devices into custom distribution boards
Who It Is For
- Electrical wholesalers and importers stocking protection devices
- Panel builders and electrical contractors installing or maintaining distribution systems
- Electrical distributors serving industrial and commercial clients
- OEM and private-label buyers who need their own brand printed on the product
- Solar lighting project buyers requiring basic circuit protection in off-grid systems
Problems It Solves
- A blown fuse can leave a circuit unprotected; this device offers a direct replacement with standard fit
- Standard cutout fuses are needed in older or legacy systems where modern breakers are not used
- Field technicians need a reliable, off-the-shelf fuse that fits common holder types
- Buyers who need a simple, low-cost protection device for non-critical circuits
- Private-label buyers require a product that can be branded and sold under their own name

- Product can be mixed with other items in a container for multi-product orders
Compared With The Alternatives
| Compared With | How This Product Differs |
|---|---|
| Miniature circuit breaker | A circuit breaker offers resettable protection but is more complex and costly. The cutout fuse is simpler and lower cost for non-critical or infrequent protection needs. |
| Cartridge fuse | Cartridge fuses are enclosed and often used in higher current applications. The cutout fuse is designed for lower current, open-air protection in standard holders. |
| HRC fuse | HRC fuses are for high interrupting capacity and are used in industrial switchgear. This cutout fuse is for general distribution use, not high fault current environments. |
Use Guide
- Ensure the fuse is rated for the circuit voltage and current before installation
- Check that the fuse holder is clean and free of debris before inserting the fuse
- Replace the fuse only after the circuit is de-energized and safe to work on
- Verify the correct fuse rating matches the circuit protection requirement
- Do not use a fuse with a higher rating than specified, as it may not protect the circuit

Utility and network buyers order protection and metering hardware in volume against a written specification. This range covers the low-voltage end of that list.
What A Cutout Fuse Does And How To Specify One
Cutout fuses sit at the service connection where nobody looks until something fails. The material of the body matters as much as the current rating.
RT18-125 FAQ
Can we have our own brand printed on the fuse?
Yes. The product supports own-brand printing for OEM and private-label buyers. Send us your logo and brand details for confirmation.
Can this be mixed with other products in one container?
Yes. The cutout fuse can be included in mixed container orders with other items from the range, such as enclosures, tools, or solar lights.
Can we get exact dimensions and a datasheet before ordering?
Dimensions and technical details are confirmed on enquiry. Please contact us with your request and we will provide the information.
How are the fuses packaged and marked on cartons?
Standard packaging is in bulk boxes with carton marking. Custom carton marking is available for private-label and distributor orders.
Can we request a sample before placing a bulk order?
Yes. Samples are available on request. Contact us with your shipping details and we will send one for evaluation.
Which product should we choose instead if we need higher interrupting capacity?
For higher fault current protection, consider HRC or cartridge fuses. The RT18-125 is intended for general distribution use, not high-interrupting applications.
