Description

The 5-pin Protector Modules provide excellent transient protection for all telecommunications systems. Modules are designed to meet specific configurations and voltage requirements in customer premises, remote cabinets, and central office applications, protecting personnel and equipment against over- voltage and over-current induced on telephone lines or local ground by lightning and AC power system faults. Gas-Tube Protector Modules contain two/three-electrode high amperage ceramic non radioactive gas-tube surge arresters and a fail-safe mechanism. These are used in areas where frequent transient over voltages are a problem or where tightly controlled breakdown values are required. The gas-tube will recover repeatedly from the over-voltage, providing 30 to 40 times longer life than the traditional. Solid-state Modules contain state-of-the-art diodes intended for use with sensitive equipment. They are available with 4 ohm (350mA) or 20 ohm (150 mA) heat coils. The diode is a fast semiconductor switch with operating voltage nearly independent of transient rise time.

Insulation resistance ≥ 1000MΩ Contact resistance difference between a line and b line: ≤ 1Ω Lower Voltage Limit:  GDT protector (100V/s escalating rate) ≥ 190V SA protector (100KV/s escalating rate) ≥ 190V Upper Voltage Limit:  GDT protector (100V/s escalating rate) ≤ 260V (1KV/us escalating rate) ≤ 800V SA protectors (100KV/s escalating rate) ≤ 260V (1KV/us escalating rate) ≤ 400V  Alarming current ≥ 2.5 A (virtual value), with responding time ﹤15 seconds
