Hydraulic-Magnetic Circuit Protection for Railway Operations

carling technologies banner

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.

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.
