OMRON Unit Case For Combined Relay For Distributed Power Supply System Interconnection K2ZC-N

Protective relays for connecting distributed power sources to the power system are even smaller, and the protection unit is also full. The spread of distributed power sources such as cogeneration systems that increase the overall efficiency of energy and wind power generation that uses natural energy is progressing. It is. This relay is a protective relay that protects the system and system by detecting in-consumer accidents in distributed power sources and power line accidents linked to distributed power sources.
This relay satisfies the models and functions described in the "System Interconnection Technical Requirements Guideline" provided by the Agency for Natural Resources and Energy, and can construct an optimal protection system with a lineup of more than 20 models.
Compatible with generators and receiving / in-house feeders.
A lineup of units with two types of relay elements.
Each unit has a built-in variable operation time circuit, facilitating collaborative design.
All models are equipped with a lock terminal that locks the relay.
DSR reliably determines directionality even in the event of a short-circuit accident where the voltage suddenly goes to zero.
Adopts a 2-stage plover terminal block with a cover for easy wiring.
