Circuit Breaker Industries (CBI-electric: low voltage), located near Johannesburg, South Africa, is a major manufacturer of electrical distribution and protection components for low voltage electrical distribution systems.
The foundations of CBI-electric: low voltage were established in 1949 as a joint venture with the Heinemann Electric Company in Trenton, New Jersey, USA. During 1986 Fuchs Electrical Industries was acquired and merged into a new company called Circuit Breaker Industries Ltd (CBI). CBI-electric: low voltage is a wholly owned company of Reunert Limited. Reunert focuses primarily on the fields of electronic and electrical engineering and is a privately owned company listed on the Johannesburg Stock Exchange.
With an exciting background of South African pioneering achievements, Circuit Breaker Industries has prospered for more than five decades to become a leader in the design and manufacture of circuit breakers for equipment (hydraulic-magnetic), miniature circuit breakers (hydraulic-magnetic), residual current devices (RCD's), moulded case circuit breakers (thermal-magnetic) and metering products for electrical applications in supply authorities / utilities, mining, original equipment manufacturers, industrial sectors and millions of households.
CBI-electric: low voltage is the only African manufacturer of circuit breakers and residual current devices. CBI-electric: low voltage has achieved international recognition for its competence and continues to represent the South African Bureau of Standards on the technical committees of the International Electrotechnical Commission (IEC), thus being instrumental in the development of international electrical safety standards.
From the early 1960s CBI-electric: low voltage began to invest in its own product development, resulting in locally developed sensitive residual current devices, circuit breakers for equipment, miniature circuit breakers and, more recently, moulded case circuit breakers utilising the Hydraulic Magnetic operating principle.
CBI-electric: low voltage has a substantial design and development capability with approximately 4% of the staff being employed in the R&D department. They include highly skilled professional engineers, technologists and technicians, who have won many national design awards over the last two decades.
Situated at the Southern tip of Africa and remote from the technical and industrial hubs of the world, it has always been necessary for CBI-electric: low voltage to be a fully vertically integrated company that manufactures most of the components, sub-assemblies and requisite tooling in-house. The resulting depth of manufacture has afforded CBI-electric: low voltage full control over the quality of its products.
This includes the design and manufacture of specialised tooling for press parts and mouldings, as well as purpose-built automation equipment. All manufacturing facilities are maintained using state-of-the-art technology.
All CBI-electric: low voltage products are markbearing and approvals are audited periodically by local and international standards authorities, such as the South African Bureau of Standards (SABS), VDE, UL, CSA, BS, CCEE, AS etc.
