Our 20A to 50A Circuit Breakers & Electrical Accessories collection covers a practical range of protection and supporting components for low voltage installations. Designed to suit a variety of domestic, commercial and light industrial setups, these products help manage higher current circuits safely and efficiently. Whether you are upgrading an existing board or planning a new install, you will find reliable options here.
This collection brings together circuit breakers rated from 20 amp through to 50 amp, alongside essential electrical accessories that support installation and maintenance. It is well suited to trade electricians, electrical contractors and knowledgeable DIYers working within consumer units and distribution boards where higher load circuits are required.
Common applications include dedicated circuits for showers, cookers, EV chargers, workshops and small commercial equipment. These ratings are often used where standard lower amp devices are not suitable, helping to protect cabling and connected loads from overcurrent in a wide range of property types.
When choosing a circuit breaker in the 20A to 50A range, it is important to match the current rating to the circuit design and cable size. You should also check the breaker type and format needed for your consumer unit or distribution board, as not all accessories are interchangeable.
The electrical accessories within this range are intended to complement circuit protection components, helping create a tidy and functional installation. Always ensure compatibility with the existing system and follow current wiring regulations. If you need other ratings, you can explore related categories across the SND Electrical website.
If you would like guidance on selecting the right 20A to 50A circuit breakers or accessories for your project, our team is here to help. Get in touch for straightforward advice and product support by fill out our contact form.
