OGRANICZNIK PRZEPIĘĆ DO 1500V
APPLICATION AREA
Low voltage surge arresters are designed to protect insulation of electric machinery as well as cables and conductors from possible damages caused by voltage surges that may be associated with commutations during regular operation and tripping of emergency devices in circuits with vacuum switching devices.
