Carling Technologies

Carling Technologies is a leading manufacturer of miniature hydraulic-magnetic circuit breakers offering maximum circuit protection for signalling and infrastructure applications in the railway industry.

With more than nine decades of product development and manufacturing experience, Carling’s products are optimal for applications with specific and stringent requirements.

Temperature stable circuit breakers for rail infrastructure

Carling’s hydraulic-magnetic circuit breakers provide significant advantages when compared to thermal circuit breakers.

Their hydraulic-magnetic design and precision mechanisms are temperature-stable within the range of -40˚C to 85˚C, enabling high-quality performance in even the most extreme operating environments.

Carling’s A-series is a compact and reliable circuit breaker unit with simple front panel operation that is well-suited to full-load amp applications.

The C-series circuit breaker is designed for high-voltage and high-amperage processes and employs a unique arc chute design, allowing it to achieve interrupting capacities of up to 10,000A.

E-series circuit breakers offer front and back mounting and heavy-duty box wire connectors with screw and stud terminals, and are ideal for high-current and high-voltage scenarios.

Carling's F-series units are intended for high-current functionality in harsh weather conditions, remaining fully operational in harsh temperatures ranging from 40°C to +85°C.

G-series circuit breakers contain a unique terminal bus connection system and common trip linkage between poles, features that are specifically designed to provide maximum protection and unit longevity.

Carling’s remote operation circuit breaker (ROCB) unit means that service, diagnostics and power distribution control operations can now be carried out in remote areas that were previously inaccessible.

The circuit breakers’ overcurrent sensing mechanism reacts only to changes of current in the circuit being protected and no heat induced tripping or cool down is necessary for resetting the breaker.

These breakers also provide common trip linkage ensuring all poles trip during overcurrent scenarios.

Safety-compliant circuit protection for railways

Carling’s line of circuit breakers are designed to comply with the latest safety regulations for electro-technical equipment in the railway industry: EN 60077, EN45545-2, NF F16-101 and IEC 61373.

Current-optimised circuit breaker systems for rail operations

Carling’s hydraulic-magnetic circuit breakers deliver accurate, dependable and cost-effective results for signalling and infrastructure railway applications.

The company is able to supply a number of different circuit breaker units, which are optimised for use with currents ranging from 0.02A-700A depending on customer needs and specifications.

Carling’s product range includes:

• The A-Series is a compact unit ideal for full-load amp applications with ratings from 0.02-50 amps, up to 80VDC, 250VAC. It is available in one to six poles and offers UL 489, UL 1077, TUV, VDE and CSA approvals.
