Product type identification:

Model number	Installed SPD	Applications
EX-JP-K3	JP-K3	Dc and Ac power superimposition circuits
EX-AP-K3	AP-K3	Dc and Ac power superimposition circuits
EX-JP-N1	JP-N1	All lines except unbalanced lines.
EX-AP-N1	AP-N1	All lines except unbalanced lines.
EX-JP-N3	JP-NM-4P	Same as type N. Particularly useful for multicircuit, multicircuit circuits.
EX-AP-N3	AP-NM-4P
EX-JP-NM-T4	JP-NM-T4
EX-AP-NE	AP-NE	Same as type N. In particular, circuits that are expected to generate interline voltages
EX-JP-NZ-1	JP-NZ-1
EX-JP-H3	JP-H3	Telemetry line etc.
EX-AP-H3	AP-H3	Telemetry line etc.
EX-JP-E1	JP-E1	ditto However, protection for equipment with high ground voltage but low wire voltage
