• BLW series universal changeover switch is one of the series products launched by Bruder Electric Jiangyin Co., Ltd. to meet customers.

  BLW series universal conversion switch is suitable for AC 50HZ~60HZ, voltage to 380V and below or DC 20V and below NC program control machine tool equipment and other electrical circuits used as medium gas control conversion and distribution equipment remote control, electrical measuring instrument conversion and servo motor, micro motor control. Can also be used for small capacity squirrel cage asynchronous motor control, at present, our company has 1, 2, 3, 4 series 10A, 16A, 20A and 63A four specifications to choose from, fully consider the requirements of users in all walks of life.

  Product features:

  BLW1(3)-16/WD series transfer switches are two products specially developed by Bruder Electric for distribution grid cover type FTU
   ◾Conventional heating current16A
   ◾Operating Angle45°、90°
   ◾Maximum number of contacts in the contact system5节
   ◾Product protection level up to IP67, meet the requirements of outdoor use
  Note: The BLW1-16/WD series has a smaller structure, which greatly saves the internal space of the cover FTU, and is recommended for use. Various special handles can be customized according to customer requirements.
