Specifications Protection Functions (Protection levels depend on breaker configuration) Long-time protection (L) Adjustable overload protection with programmable pickup and delay. Short-time protection (S) Adjustable pickup and delay with I²t ON/OFF. Instantaneous protection (I) Adjustable magnetic trip for short-circuit protection. Neutral protection (N) (when neutral CT or module is installed) Note: PR122/D-M supports standard protection suite of PR122/D series; ground-fault “G” protection requires the respective version (not included in D-M). Metering & Measurement (M – Metering Function) Phase currents Neutral current (with module) Ground current indication Voltage values (with voltage module) Power & energy (kW, kWh, kVA, kVAR) Frequency Power factor Thermal capacity Trip history & events Display & Operation Large multifunction LCD display Local pushbuttons for settings and navigation LED indicators for status and alarms Adjustable Settings L – Long-time pickup & delay S – Short-time pickup & delay, I²t enabled/disabled I – Instantaneous pickup setting N – Neutral protection (optional) Supported Current Ratings Compatible with Emax/Emax2 breakers rated: 160 A – 6300 A, depending on frame size and CT rating. Accuracy Current measurement: typically ±1% Voltage & power measurement (with module): high accuracy per IEC standards Tripping characteristics compliant with IEC 60947-2 Communication (Optional) Supports ABB communication modules such as: Modbus Profibus DeviceNet Ethernet gateways (via expansion) Enables remote settings, monitoring, and event logs. Power Supply Self-powered via CTs Optional auxiliary power depending on configuration Compliance IEC 60947-1 IEC 60947-2 CE and international approvals (breaker-dependent)
