Type 3 surge protector DM1-230

class IIIfor telecom applicationscombined

DM1 is the range of surge protection devices (Type 3 / Class III) for very fine protection of sensitive equipment. Complete with a built-in EMI filter. DIN rail monobloc format. Features • Suitable as the final stage of protection in panels that have Type 2 surge protection devices installed upstream, in installations with electromagnetic interference which might interrupt, degrade of limit system performance. • The residual voltage of these devices is lower (finer protection) than that of Type 1 or 2 protectors. • They should be installed as close as possible to the equipment being protected. • Series connection for applications up to 8 A rated current. • With electromagnetic interference (EMI) filter. • Combined voltage pulse with 1.2/50 μs waveform. Uoc: 6 kV. • Single-phase networks. Standards and certifications • IEC 61643-11 • EN 61643-11 Applications • Building • Industry • Telecom • Water treatment
