EMP protection units B84320Z0010H033 Analog communication and control lines B84320Z0010H035 General The EMP protection unit is sequenced, i.e. to use simultaneously the benefits of inert-gas-filled surge arresters (extremely high surge capability) and of varistors (fast response). They are isolated by a series inductor. The arrester is housed in a plug-in socket, so it can be removed and tested without detaching the lines. Note on voltage figures: The maximum voltage on the filter output depends primarily on the rise time until the arrester responds. For this reason the maximum voltage on the filter output is stated in the following table as a function of the rising edge dv/dt of the pulse.
