ATEX Approved Variants of DC Circuit Breakers for Chemical, Oil and Gas Industries

Scattergood & Johnson, renowned in the electrical engineering distribution industry for high levels of stock, service, technical support and customer satisfaction, now stocks DC electronic overcurrent protection products for automation applications from E-T-A Circuit Breakers (Germany).

According to Robert Hargreaves, Managing Director of Scattergood & Johnson: “E-T-A is a quality designer and manufacturer of electronic products for DC circuit protection in industrial applications. The company’s ESX10 family of electronic overcurrent protection products have proved themselves in a number of UK companies by reducing costly downtime and reducing danger to personnel in automation applications: some versions have ATEX approval for Ex zone 2, making them particularly useful for applications in the chemical, petroleum and gas industries.”

Albert Pipe, General Manager of E-T-A Circuit Breakers, added: “Scattergood & Johnson are well respected as a key distributor of plant and machine safety products to heavy industry and we are delighted that their customers will have ready access to stock of our ESX10 family which offers variants for plug-in to rail mounted modules or for direct rail mounting. These provide the best possible protection for loads, such as controls, sensors, transformers and solenoid valves, which are fed by switch-mode power supplies or battery-buffered power supplies.”

E-T-A circuit protectors prevent costly downtime and speed fault diagnosis. If a piece of plant equipment becomes faulty, the E-T-A circuit protector trips and isolates that specific piece of equipment, allowing the rest of the plant to continue operating normally. For processes powered by 24V DC switch-mode power supplies without circuits protected by a device such as the ESX10, an overload in a single circuit will cause the power supply to shut down the output to all the circuits it supplies. ESX10 options include remote reset and status indication.
