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.
