High End AC motor 3 Phase Capacitor Switching Contactor 32A 40A

High End AC motor 3 Phase Capacitor Switching Contactor 32A 40A

Description:

UKC1 series swithing capacitor contactor (hereafter called " the contactor " for short ) are the contactors specially used for make and break of low voltage shunt capacitors and widely used in reactive power used for make and break of capacitor up to 60kvar in electric power system of AC 50Hz and rated working voltage 380V for the purpose of improvement of power factor. We have 9A, 12A, 18A, 22A, 32A,40A, 50A,65A, 75A, 85A Contactors.

IEC utilization categories

The current rating of the AC/DC contactor depends on utilization category. Example IEC categories in standard 60947 are described as:

AC-1 - Non-inductive or slightly inductive loads, resistance furnaces

AC-2 - Starting of slip-ring motors: starting, switching-off

AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up to speed. (Make Locked Rotor Amps (LRA), Break Full Load Amps (FLA))

AC-4 - Starting of squirrel-cage motors with inching and plugging duty. Rapid Start/Stop. (Make and Break LRA)

Specifications:

Operation Condition:

1. When the switch is closed condenser must be discharged before recharged.

(Maximum residual voltage at terminals ≤ 50V)

2. In working voltage 500V (Ue=500V), 100,000 times for UKC1(D)-9C~40C and 80,000 times for UKC(D)1-50C~85C

3. To prevent short current, gG type Fuse must be 1.5~2 times than rated current.

4. It must be separated from resistant wire

5. The average temperature over a 24-hour period, in accordance with standards IEC70 and 831 is 45 degree
