General
The air insulated type switch disconnectors(Load Break Switches) of NAL and NALF areintended for indoor installation in air-insulated switchgear systems. With switching,disconnecting and protection (Combinated with Fuses) for medium voltage network such asdistribution transformer, motors, capacitor banks, etc.
Standard
The LBS complies with the following specifications in accordance with DIN VDE and therelevant IEC publications:
60129, 60265, 60694, GOST 1516.3-96, GOST 17717-79, and CSA Standard No.C22.2, No. 193, and IEC62271-105, all of which consider switches for general use and ensurethere is safe switching coordination between a switch disconnector and a current limiting fuse.
Product features
A NAL Load Break Switch (which interrupts load currents up to 1,250 A) and a small fault-current circuit combined with a fuse base (F) and current limiting fuses (which break largeshort-circuit currents) create a NALF-type Load Break Switch that provides protection againstamajority of fault types in a modern electric network.
Technical data
The NAL&NALF Load Break switch complies with IEC standards 60129, 60254 and 60694concerning general purpose switches and IEC Standards 420 and 62271-105 regarding correctco-operation between switch disconnector and fuse.
