THT8-ST Delay on Motor Star Delta Timer Soft starter AC230V 415V AC/DC12V-240V Delta Relay Motor Starter
****This is a time relay for delay on starting motor star triangle, to protect motor. It does not drive motor directly. Relay need connect with ac contactor, then ac contactor connect with motor to control.
General
Applications
-Designated for delay ON of motors star delta.
Function Features
-Time t1 (star) :
time scale 0.1 s - 10min devided into 4 time ranges
rough time setting by rotary switch.
-Time t2 (delay) :
time scale 0.1 s - 1 s
time setting by potentiometer
- Relay status is indicated by LED.
- 1-MODULE,DIN rail mounting.
