Parameters Category Parameter Specification for OFAFC000GG80 General Type Electronic, Adjustable, 3-Phase Overload Relay Series OFAF Series (System Pro M compact®) Trip Class Class 10 (IEC/EN 60947-4-1) Maximum Setting Current (Iₓ) 80 A (Adjustable range, e.g., 22 - 80 A) Protection Functions Overload Protection Electronic I²t thermal model with ambient temp. compensation. Phase Loss Sensitivity Yes. Fast tripping on loss of phase (within seconds at FLC). Phase Unbalance Protection Yes. Protection against excessive current asymmetry. Locked Rotor Protection Inherent via fast trip on high starting current. Settings & Controls Current Setting Rotary dial, adjustable within specified range. Reset Mode Manual (push-button) or Automatic (selectable via slide switch). Test Function Integrated TEST button. Trip Indication Mechanical flag (red) and/or LED. Phase Loss Indication Separate LED indicator. Electrical Characteristics Rated Operational Voltage (Uₑ) Up to 690 V AC, 50/60 Hz (for main circuit isolation). Auxiliary Contact Voltage Typically ≤ 600 V AC/DC. Power Supply Self-powered via internal current sensors; no external supply needed. Auxiliary Contacts Trip Contact (95-96) 1 NC (Normally Closed) – Breaks contactor coil circuit. Alarm/Signal Contact (97-98) 1 NO (Normally Open) – Makes on trip for remote indication. Contact Rating AC-15: 6 A at 230 V; DC-13: 0.3 A at 230 V. Current Sensors & Burden Sensor Type Integrated Current Transformers (CTs). Continuous Withstand 1.2 x Iₓ (Max Setting) continuously.
