UP3B-235 UltraLinx 66 Block from ITWLinx is a voice high-speed data 66 block surge protector with Sneak Current Protection which protects against fires caused by overloads and power crosses. The Single Pair Protection method protects only the lines requiring protection. The Solid-state Protection automatically resets without user intervention and provides the fastest response to transient voltages by quickly diverting damaging surges to ground. It utilizes replaceable 350mA fuse for protection and 2 indicator lights for Protection and Ground Connection indications.

These 16 AWG steel building entrance terminals feature reliable 66 block style Quick Clip connectors for both the input and output terminals. Connectors can accept up to an 18 AWG line termination. Also included are multiple external and internal ground lugs, as well as splice chambers and various types of security covers. UL approval standard on all terminals. Standard 5-pin protector modules, available in Analog and Digital versions, can be purchased separately or loaded. The CR-2606QCQC is a 6 pair 66 block. The protection modules are sold separately.

The 2650QC/QC 50 Pair lightning protected 66 block, 16 AWG steel building entrance terminals feature reliable 66 block style Quick Clip connectors for both the input and output terminals. Connectors can accept up to an 18 AWG line termination. Also included are multiple external and internal ground lugs, as well as splice chambers and various types of security covers. UL approval standard on all terminals. Standard 5-pin protector modules, available in Analog and Digital versions, can be purchased separately or loaded. The CR-2650QC/QC is a 50 pair 66 block. The protection modules are sold separately.

The 100 Pair Circa Telecom 1880ENA1/NSC-100 16 AWG powder coated steel building entrance terminal features an industry standard 110-Style Connector for both input and output terminals. Connectors can accept up to 22 AWG line terminations. Also included are multiple external and internal ground lugs.

The 6 Pair Circa Telecom 1880ENA1/NSC-6 16 AWG powder coated steel building entrance terminal features an industry standard 110-Style Connector for both input and output terminals. Connectors can accept up to 22 AWG line terminations. Also included are multiple external and internal ground lugs.

This is a premium series 5 PIN solid state protector module that is designed to provide superior transient and power fault protection for most standard telephone line applications. These solid state modules are suited to applications that require the protection of sensitive telephone equipment due to their nanosecond reaction time. The characteristics of the solid state protector are far superior to gas tube technology in speed and are virtually immune to overshoot, aging and failure due to repeated tripping. 

The 4 – Series features PTC (positive temperature coefficient) technology. These optional self-resetting current limiters provide effective protection from ‘sneak current’ faults. The PTC is vastly superior to the heat coil solution, which requires that the module be replaced after each ‘sneak current’ event.
