Surge protector for railway applications SFLM-xxx

for signal transmissionexplosion-proofbuilt-in

SFLM-xxxsignal surge protector is suitable for railway system mainly applied tO signal wiring board;Combined with lightning protection wiring cabinet，itprotect seach signal transmission line that needs protection from lightning,andprotects the subsequent system and its equipment against damage fromovervoltage and overcurrent caused by lightning,industrial interference，etc. ● The module mainly has the functions of surge absorption, potential clamping, and ground leakage. ● No leakage or after-flow, long service life. ● Built-in trip device, safe and reliable. ● The module is directly inserted into the module base of the distribution board terminal, and the lightning protection components and the transmission cable realize zero-distance connection, and the protection effect is good. ● The module can be plugged or replaced when powered, without any impact on the circuit. Installation is convenient. ● The module coating is made of high temperature resistant, aging resistant, explosion-proof and flame-retardant materials. ● The module is equipped with test points, which can test all the internal components of the module separately. ● Different models have different discriminator pins to prevent incorrect insertion.
