E-T-A introduces compact, high-capacity DC disconnect switch
E-T-A Circuit Breakers, quality designer and manufacturer of a broad range of electro-mechanical and electronic products for circuit protection, has introduced a new high-capacity DC disconnect switch providing physical isolation for up to 1500V DC in a very compact design.
Originally developed for photovoltaic systems, to be fitted between solar power modules and the power inverter, the double pole E-T-A DC Disconnect switch can also be used in many other DC circuit protection applications including ungrounded systems. Measuring 99mm x 90mm x 92.5mm the enclosure is DIN-rail mountable, ideally suited for installation in distribution enclosures. The hybrid technology requires no external power supply, allows reliable disconnection in the event of low currents and ensures a low-wear contact system.
E-T-A designs and manufactures a broad range of electro-mechanical and electronic products for circuit protection, control and instrumentation, including the world’s largest range of circuit breakers for equipment (CBEs). E-T-A equipment is specified and installed by a wide variety of industrial OEMs and end-users, with key markets including air, sea and land transport, process control, computers and communications, medical equipment, domestic appliances, machine tools and robotics.
E-T-A is an international company with headquarters in Altdorf, Germany and production facilities in several other countries, together with marketing, sales and technical operations throughout the industrial world. Its European, North American and Far Eastern markets are served by some 1,500 employees.
