رله های اندازه گیری EMR4-EMR5
رله های اندازه گیری EMR4-EMR5 ایتون (مولر) جهت انداژه گیری و نظارت طیف گسترده ای از برنامه های کاربردی در تکنولوژی تابلو های ،اتاق های کنترل و فرمان طراحی شده اندو در انواع زیر موجود می باشند:
Applications:
- Current monitors for universal use
- Phase monitors for monitoring destruction/damage protection for individual system sections
- Phase sequence relays monitoring the rotating field
- Unbalance relays for reliable phase loss detection
- Multifunctional three-phase monitors
- Asymmetric phase monitoring relays in a single device
- Level monitoring relays for monitoring fill levels
- Earth leakage monitors for enhanced operational safety
Versions:
