ANSHI Subscriber Terminal Block Module

The STB module provide a connection point between an exchange-side cablepairand a distribution pair. It incorporates a 5-point plug in moduletoprovide continuity and a range of other options. Removal of theplug-inmodule does not disturb wire connections but makes contacts tothemavailable for testing of both sides of the network.Current conducting capacity 20 A, 10 A per conductor for 10 minutes at least, without causing deformation to the module Insulation resistance Dry atmosphere: >1010 Damp atmosphere(ASTM D618, procedure F): >1010 Salt fog:(ASTM B117) >109 Immersion in water: (15 days in 3% NaCl solution) TELCORDIA TR-NWT-000975 (Formerly Bellcore)>109 Contact resistanceRmaterial + Rbridge contacts + Rwire contacts <10 m Increase in contact resistanceAfter climatic tests: <2.5 m After 50 reinsertions: <2.5 m Dielectric strength >3,000 Vdc for 1 minute Mechanical characteristics Protector ground contactTinned hard brass Continuity contactTinned hard brass Plug-in module bodyFlame retardant (UL94) fiber-glass reinforced polycarbonate Plug-in module sealantGel O ring EPDM Internal ConfigurationContinuityAS-STBSize: (mm) (H x W x D): 40 x 50 x 20 (without Protection) Environment condition: 5-40 degree Celsius ,Relative humidity <85% (+30 degree Celsius),Atmospheric pressure: 70-106KPa Pulling-out force: tin bronze and silver plating (20-40uinch), pulling-out force not less than 25N The performance of anti-burn: PBT or anti-burn PC ,Combustibility achieved GB/T 5169.7-1985 standard Type: 1) without Protection: DIN rail drop wire connector with continuity plug. The plug is grey in colour and has only the function of electrically connecting the incoming pair with the outgoing one. 2) with Protection: DIN rail drop wire connector with 3-point protection: It differs from previous one by having a RED plug, which, beside providing continuity, also integrates a 3-pole gas arrestor (GDT), rated 230V, 5A/5kA Life: durability 200 cycles (0.4-0.6 diameter), durability 50 cycles (0.6-1.2 diameter) Testing-generalElectricalMechanicalEnvironmental and so onaccording to industry standard Material and Production Stamp and Product Branding: according to Client standard Weatherproof dropwire module for outdoor applications, designed for being fitted onto DIN 35 rails – Built-in disconnection and testing function without removing the conductors – Can be equipped with overvoltage protectionIDC Type Connections drop wire connection module No wire stripping subscriber terminal block Rugged Design and Construction IDC Type Module Drop Wire Connection Module Termcon Terminal Block Subscriber Terminal Block Rugged Design and ConstructionSubscriber Terminal Block Module (STB) without Protection
