CT-T1+2+3/2+0-350-FM
Article Nr. : 960409
They provide extremely high discharge capacity with at the same time very low protection levels and they also do not need any damageable internal or external electronic trigger. Combined arrester with rare-gas-filled spark gap and very low protection level < 1.0 kV for the use in single-phase TN systems.
