Microprocessor-based time-overcurrent relay - MICRO-51
MICRO-51 microprocessor-based overcurrent relays are used for phase and ground overcurrent protection in utility, industrial and commercial electrical power systems.
The Micro-51 operates from conventional 5A or 1A secondary current transformers. The relay is self-poered from the current, therefore, there is no continuous drain on the control voltage supply. Settings are made by front panel switches.
- Relays for different application ranges
- Range from simple protection relays used as back-up protection to specialized relays
- Relays for both well-established proven technologies and for modern technology
- Optional arc detection
