The 2440 Series protector provides highly reliable overvoltage and self-resetting sneak current protection for copper pair voice-band and high speed data circuits. Bourns’ high-efficiency balanced Gas Discharge Tube (GDT) is UL approved for use without a Back-Up Gap (BUG). Its Switch-Grade Fail-Short mechanism ensures superior thermal protection with fast acting, highly reliable response to thermal overload conditions. This combined technology provides lower capacitance, higher reliability and long life. Bourns® PPTC Resistors are used for sneak current protection, providing reliable and self-resetting performance with less than four ohms of resistance. Bourns® 2440 protectors can be used universally for broadband voice and data circuits including ADSL, ADSL2+, VDSL, VDSL2 and high-speed ethernet. The 2440 Series is an innovative, reliable and effective choice for 5-pin protection of copper pair circuits. Characteristics Tested per UL 497, CSA C22.2, Telcordia GR 974, 1361 and SBC SR 5165.
