What we stock
We carry nearly 1 000 protection products. That includes miniature circuit breakers (MCBs), large frame moulded case breakers (MCCBs), DC circuit breakers, earth leakage units, AC and DC surge protectors, isolators, change-over switches, motor protection, timers and kilowatt meters.
Brands
Choose from trusted names including Schneider, Chint, Onesto, CBI and Hager. Whatever your preference or budget, you can compare the same ratings across brands in one place.
Choosing the right breaker
Match the amp rating to the cable and the load, the pole count to the circuit (single, double, three or four pole) and the kA breaking capacity to the fault level at your board. Add earth leakage and surge protection to protect people and equipment. Our branch teams can help you match a breaker to your distribution board.
Popular ranges
Our largest ranges are regular circuit breakers (nearly 500 lines), large frame MCCBs, surge protectors, DC circuit breakers, isolators and earth leakage units. Motor protection, change-over switches, timers and LED indicators complete the board, and kilowatt meters let you monitor consumption.
Why buy from Citilec
With several brands in every rating, you can compare price and availability in one place and keep a mixed job to a single order. We can quote for the full set of breakers a board needs and have it ready for collection.
Pickup and delivery
Collect from any of our four branches, or WhatsApp your list ahead of time. Delivery anywhere in Gauteng is free on orders over R1 000. Trade customers can open a COD or credit account.
Buying tips
- Choose the breaker amp rating to match the cable size and load it protects.
- The kA rating shows the fault current the breaker can safely interrupt.
- Add earth leakage and surge protection to protect people and equipment.
Frequently asked questions
What is the difference between an MCB and an MCCB?
An MCB is a miniature breaker for final circuits in a distribution board, usually up to about 125 A. An MCCB is a larger moulded case breaker used for higher currents, such as main supplies and sub-boards.
What does the kA rating on a breaker mean?
It is the maximum fault current the breaker can safely interrupt. Choose a rating that is at least as high as the prospective fault current at your board.
Do you stock earth leakage and surge protection?
Yes. We stock earth leakage units and AC and DC surge protectors from several brands.
Do you sell DC breakers for solar systems?
Yes. We stock DC circuit breakers, DC isolators and DC surge protectors for solar installations.
Can you help me choose a breaker for my board?
Yes. Bring the details of your board and circuit to any branch, or send them on WhatsApp, and our team will recommend a suitable breaker.
