FAQs
The NZMH2-A200-NA uses a front screw connection for straightforward wiring and secure termination. Begin by verifying the NZM2 frame compatibility, mount the device in an appropriate panel enclosure, and tighten each terminal to the specified torque. Ensure correct phase alignment and trip setting within the 160-200 A range. This design reduces field complexity and speeds up commissioning while maintaining safe access for wiring and maintenance.
Key adjustments include the overload setting 160-200 A on the Ol Protector and the delayed short-circuit release 1200-2000 A. Configure the thermal and magnetic trip according to the motor load and feeder protection needs. After installation, verify coordination with downstream protection devices, perform functional tests, and document the settings for maintenance records to ensure consistent protection throughout the life of the installation.
