Circuit breakers supplier: local availability you can rely on
When a board, project or site needs reliable overcurrent protection, downtime and wrong parts cost real money. Communica supplies a broad selection of miniature, DIN-rail and moulded-case circuit breakers from brands stocked in South Africa so you can get the right device quickly - whether you need a single replacement for a lab bench, a set of breakers for a teaching lab, or bulk units for an installation. Benefit from same-region availability, branch pickup in Samrand, Pretoria or Cape Town, VAT invoicing for procurement, and support from staff who understand practical installation constraints.
Why local sourcing matters
Lead times from overseas can derail project schedules. Choosing a local circuit breakers supplier reduces delivery uncertainty and helps with documentation: VAT invoices, part numbers and collection options from our Samrand warehouse save time for procurement teams and technicians.

Quick specification callouts
Use this quick reference when selecting a breaker for a panel or project:
| Type | Typical Ratings | Use |
|---|---|---|
| MCB (Miniature) | 6 A - 63 A, B/C/D trip curves | Lighting, sockets, small motors |
| RCD / RCCB | 10 mA - 300 mA sensitivity | Personnel protection, Workshop outlets |
| MCCB | up to 2500 A, adjustable trips | Main distribution, industrial feeders |
Compatibility note: match the trip curve to the expected inrush (motors and LED drivers need different curves); use correct frame and busbar spacing when replacing breakers in existing distribution boards. For hands-on help, check branch stock and opening times at Branches & Trading Hours before you visit.
