The ALBS is a medium voltage air insulated, lateral load break switch designed for rated voltages from 6kV to 24kV and rated currents of 630A. Mounted within a switchboard enclosure (e.g. LCA-A) the ALBS is suitable for indoor or outdoor applications depending on the construction of the switchboards.
The ALBS is an improved version capable of higher performance. At the same time it is compactly designed using lighter and stronger engineering materials, making it an altogether smaller product.
The ALBS is a three phase air "puffer" load break switch which uses compressed air as an arc quenching medium. The improved air compression system enables a higher breaking capacity.
The spring charged driving mechanism of the ALBS is located at the front of the switch for ease of access during service.
Due to its simple and compact design the ALBS is both an economical as well as effective solution for medium voltage power distribution and protection applications.
The ALBS is designed for normal operating conditions and is type tested in compliance with IEC60265-1, IEC 60420 and IEC 60694.
