Multiple sources can cause damage to the telephone communication equipment, including lightning, electrostatic discharge (ESD), AC line power contacts and induction. 2Pro TM2P-10271 element contributes to the current overload situations provide current limit, voltage clamp in voltage under overload conditions. After the lifting of the fault, power recovery, 2Pro components will be reset to the continuous operation of the equipment.

The 2Pro element is helpful to meet the cost sensitive PSTN (public switched telephone network) and VoIP (IP phone) that may need to reset circuit protection components in telephone equipment. The VoIP gateway is used widely in household and business environment as well as the main voice transmission mode needs to safety and reliability of equipment with high. 2Pro circuit protection components helps manufacturers to comply with global safety standards, including UL 60950, TIA-968-A, IEC 60950 and ITU-T K.20/K.21. The protector UL 497A authentication can also help provide ESD protection.
