2440 Series 5-Pin Surge Protector
Bourns
®
5-Pin Model 2440 series is a new generation of Bourns
®
telecommunications protectors for superior performance and long life.
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.
