What is 1 Pair MDF Protector Used for? 


   DESCRIPTIONS   

1 pairs MDF protector (TP-1501-1EGP) is used for LSA modules, which forms the protection circuit for the protection of exchange room equipments and personnel against over voltage and over current, for mainly as follows:

• The surge voltage caused by lightning on or around the outside lines.
• The short-time AC voltage inducted on external lines, when the power line, the power system or the electric railway system is broken down in the neighborhood of the outside line.
• The outside line directly collides against a 220 V power line.

 
The housing of the protector is flame retardant, high temperature resistance and aging resistance. It is 1 pair modular design protector. Its compact form factor ensures compatibility with high-density cabling environments. Reliable, field-tested, and compliant with major telecom standards, this protector supports network integrity across a wide temperature range and is suitable for both indoor and sheltered outdoor environments.

    MAIN FEATURES    

• Modular single pair design: The protector is engineered as a modular unit that covers only one telecom pair, enabling precise and selective protection.
• Easy installations: The device can be inserted directly into standard LSA disconnection modules without tools, thanks to its plug-in form factor.
• Maintenance free: Built using high-quality components and solid-state technologies where applicable, the protector requires no periodic maintenance or calibration.
• Graded 5 point protection: Incorporates a multi-stage protection mechanism.
• Flame retardant performance: The housing is molded from UL94-V0 rated thermoplastic, which self-extinguishes in case of fire.
• Total front operations: All insertion, removal, inspection, and replacement can be performed from the front face of the frame or module bay, eliminating the need to access the rear or dismantle adjacent units—ideal for quick maintenance in high-density racks.
• Over-voltage and over-current protection: Protects lines from dangerous voltage spikes and current surges due to lightning or power induction.
• Integrated with GDT technology: Utilizes gas discharge tubes to quickly discharge over-voltage conditions to ground.
• LSA module compatibility: Specifically designed to plug into standard 10-pair LSA disconnection modules.
• Fail-safe operation: In the event of catastrophic surge, unit will short and ground line to prevent equipment failure.
• Compact dimensions: Space-saving form factor for high-density MDF racks.
• Replaceable design: Easy field replacement of failed protectors without rewiring.
