Application Range
MCTRANS Series Dual power transfer switches (ATSE MCTRANS Series Dual power transfer switches (ATSE)
are advanced products which adopted the early twentieth century technology. It can used for two-way power
source infrequently transferred switched with rated insulation voltage AC800V and DC250V, rated current 20 to
5000A, rated frequency 50 or 60 Hz.
It mainly applied in occasions where need uninterruptible power supply, such as malls & ofce buildings, post
communications, re-ghting, military, mines, ship & vessel, escalator & elevator and industrial assembly lines,
etc. in order to meet the assembly lines, etc. in order to meet the requirements of providing more reliable
power sources.
The products are characterized by its small size, easy operation, fast switching speed and high reliability.
MCQ2 Model is double segments (without Neutral Position, transfer sequence: Mains to Generator) dual
power transfer switch.
MCQ3 Model is three segments (with Neutral Position, transfer sequence: Mains to Neutral to Generator) dual
power transfer switch.
