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.
Introduction
The LBS type NAL/NALF is based on a modular principle. The basic unit consists of a framewith insulators and current carrying parts. Two different types of operating mechanisms.snap action mechanism type K or stored spring energy mechanism type A, can be mounted onthe frame. Fuse bases type F, with or without fuse tripping mechanism, and an earthing switchtype E/EB, suitable for both direct mounting and free standing components, complete thebasic equipment of a switch disconnector. These modules can be easily configured accordingto customer expectations. Accessories, such as shunt trip, under-voltage release, auxiliaryswitches, motor operation and various systems for manual operation can easily be added.
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.
Operating conditions
Ambient temperature:
 Maximum +40ºC Maximum 24 hour average +35ºC
 Minimum (according to "minus 5 indoorclass" )-15ºC·
Humidity:
 Daily average ambient air relative humidity ≤ 95%, on average ≤ 90%;
 Saturated vapor pressure of daily mean values s 2.2 x 10-3Mpa, on averages 1.8 x10- 3Mpa;
 Maximum site altitude:≤ 1000 M above sea level,

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.
