Detailed content
- Functional Features:
- Bimetallic strip technology provides precise, temperature-dependent overload protection that matches motor thermal characteristics.
- Phase loss detection prevents motor burnout from unbalanced currents, a common cause of premature motor failure.
- Adjustable current setting allows calibration to specific motor ratings for optimal protection.
- Trip indicator light and auxiliary contacts signal overload events for integration into control or alarm systems.
- Lockable reset button prevents accidental restarting after a trip, enhancing operational safety.
- DIN rail mounting simplifies installation alongside AEG contactors and other control components.
- Application Scenarios: Industrial pump systems for protecting water circulation and chemical transfer pumps; HVAC systems safeguarding large air handler and chiller motors; Manufacturing lines protecting conveyor, mixer, and compressor motors; and Mining equipment shielding heavy-duty ventilation and material handling motors.
