Rated Current: Select according to continuous feeder loading.
-
Breaking Capacity: Verify the required short-circuit breaking current.
-
Protection Coordination: Consider relay settings and upstream/downstream protective devices.
-
Controller Functions: Confirm measurement, protection, monitoring, and reclosing requirements.
-
Communication: Specify remote control functions and supported protocols.
-
Installation: Consider outdoor environment, mounting arrangement, and maintenance access.
Request a Technical Quotation
Please provide the system voltage, rated current, prospective fault current, controller requirements, communication needs, installation conditions, and applicable technical standards.
SUT Electrical can review project specifications and discuss suitable ZW20 or ZW32 configurations.
Fault interruption times and network protection performance depend on the equipment and system settings.
