### **Cons**
1. **Limited Current Rating**
- The **DILM9-10** model is rated for **up to 10A (approx. 7.5kW/10HP at 230V)**, which may be insufficient for larger motors.
- For higher power applications, a larger starter (e.g., DILM16 or DILM25) would be required, increasing cost.
2. **No Built-In Remote Control in Basic Models**
- The standard model may lack **remote start/stop** functionality without additional wiring or accessories.
- Some applications may require external pushbuttons or PLC integration for full control.
3. **Dependence on External Overload Relays (in Some Configurations)**
