The SMH-TC surge arresters are designed for low power DC signal lines up to 1 A and wired in series. These are especially suitable for analog signals such as 0-10 VDC and 4-20 mA. The units provide longitudinal and transverse protection. Initial protection comprises a 3 pole gas discharge tube and diverts the primary surge energy. Fine protection is achieved by the use of fast bi-directional silicon avalanche diodes. Series line impedance ensures energy coordination between the coarse and fine protection stages at all levels of the surge. To protect against electric shock and fire which can occur when power frequency occurs between the power and signal lines (mains incursion) a thermal clip is used on the primary protection stage to divert the surge current to ground.
