Features
- Features overload given time protection (on/off ), inverse time overload protection, open-phase, three-phase current unbalance protection function;
- Built-in 4 overload curves are available to meet different occasions;
- Panel with start and stop buttons, terminal block can be external connected with start and stop buttons with simplified wiring;
- Auto-start function can open the auto-start function and set the start-up delay. In case of power resumption or reset after power failure, the protector start automatically as per the set auto start delay, free of any human intervention;
- Fault memory and its indications: In case of motor failure, the indicator displays the fault type, while the bottom row LED flashes and displays the fault code;
- Mouning mode: screw mounting.
Application
- Motor protection and control for a variety of drives
- Application-specific standard configurations resulting in a shorter relay setup and commissioning time
- Preconfigured solutions for utility distribution and industrial applications
Specification
1.Altitude: should not exceed 2000m;
2.Ambient tempeature: -5℃~+40℃, and the average temperature in 24h should not exceed +35℃；
