Thank you for viewing. Easy to install in the panel. Peace of mind even when deteriorated. Excellent responsiveness, no continuous current. With terminal cover to prevent electric shock. Protects between lines and to ground with one unit. ■ No deterioration contact output terminal Characteristics [Maximum continuous operating voltage (50/60Hz) Uc] Single-phase 2-wire 130V, 250V AC *1 Single-phase 3-wire 110V/220V AC Three-phase 3-wire 250V AC [Nominal discharge current (8/20μs) In] Between lines, to ground 5kA [Maximum discharge current (8/20μs) Imax] Between lines, to ground 10kA [Voltage protection level (Note 1) Up] Between lines: 1300V or less To ground: 1500V or less [Operating start voltage (Note 2) Between lines] 540V ± 10% [Operating temperature range T] -20℃ to +50℃ [Enclosure protection rating (Note 3)] IP20 [Applicable wire range (Note 1)] 5.5mm^2 to 14mm^2 [Weight (approx.)] 260g ● Compliant with JIS C 5381-1.
