NWC 1101 AC Undercurrent Relay
NWC 1201 Overcurrent Relay

The NWC units directly measure currents up to 10A RMS. For higher current values, an additional current transformer of 1A or 5A must be used. A separate power supply is required and must be specified when ordering. Both units have 2 LEDs, a green one for POWER ON, and a red one for FAULT.

The NWC 1101 will alarm if the current falls below the preset values. In the Failsafe mode, the alarm relay will be activated immediately and will be resent after the selected time delay. For active mode, the relay will reset to normal operation when the current level rises above the preset setpoint + hysteresis value.

The NWC 1201 will alarm if the current rises above the preset values. In the Failsafe mode, the alarm relay will be activated immediately and will be reset after the selected time delay. For active mode, the relay will reset to normal operation when the current level rises above the preset setpoint + hysteresis value.
