1777A SCR Soft Starter assembly consists of six thyristors

SCR ASSEMBLY 

Soft Starter Assembly:

Features:

The assembly consists of six thyristors.

Two anti-parallel thyristors as a single

phase AC switch.Then combine the three

AC switch to use for

soft start three phase asynchronous

AC motors.Conside soft starter start time

is short.After start the motor,

current donot through soft starter assembly.

So SCR not with additional radiator.

just radiating use conductive copper.

Applications:

Used in colliery, mining three phase asynchronous motor`s soft starter.We can customize SCR assembly according to your motor`s current,voltage.Detailed installed size,also accept customize.

Main technical parameters:

The SCR assembly`s current capacity and off-state voltage,depending on the SCR part number that you choose.

E.g: below is two KP800-40 SCRs make up one phase assembly.Parameters as below:

IT(rms)=1777A

Vdrm>=4000V

Idrm<=70mA

Vtm<=2.6V(Itm=2400A)
