Reliable local stock of circuit breakers for projects and installs
When a project or site needs protective switching now, long lead times hurt schedules. Communica offers a broad range of circuit breakers - MCBs for lighting and sockets, RCBOs for combined protection, and thermal-magnetic breakers for motor circuits - stocked in South Africa to minimise delays and keep student labs, maker spaces and site installs moving. Our advantage is visible stock, branch pickup, and technical help that speaks practical application rather than sales jargon.
Why local stock matters
Local availability reduces waiting, simplifies procurement, and ensures you can collect from Samrand or a city branch the same day. For tertiary labs and engineering teams who need VAT invoices or account quotes, our processes are set up to support institutional purchases and audit trails.
What we stock and who it's for
We cater to electricians, maintenance technicians, engineering students and procurement teams. Typical offerings include DIN-rail MCBs (B, C characteristics), RCBOs for final circuits, MCCBs for distribution, and accessories such as busbars, auxiliary contacts and lock-off devices.

Specification callouts to check before you buy
When choosing a breaker, check these core specs - they determine safe fit and performance on-site:
- Rated current (In): 6A to several hundred amps depending on application
- Breaking capacity (kA): ensures the breaker can interrupt prospective fault currents
- Tripping curve (B, C, D): select B for resistive/lighting, C for mixed loads, D for motor inrush
- Number of poles and neutral handling: single pole, single pole + N, or 3P/3P+N for three-phase
Quick compatibility guidance
Match physical size (DIN modules), busbar or rail mounting, and terminal clamp style to your enclosure. For education labs where flexibility matters, choose modular RCBOs or DIN-mounted trip units so circuits can be reconfigured without rewiring. Learn about our brands and options: Shop by Brand.
