All trip settings can be entered through the intuitive menu structure which provides prompts in clear and plain English. All pickup oints are displayed both as a percentage, and in actual amps, making the transfer of settings from original trips fast and easy. The below table lists the functions and settings available with every ETC-12 retrofit.
| Function | Pick Up Range | Delay Range | Notes |
| Available current sensor tap ratings | N/A | N/A | 40A, 70A, 80A, 100A, 120A, 150A, 200, 225, 300, 400, 600, 800A, 1000A, 1200A, 1600A, 2000A, 2400A, 2500A, 3000A, 3200A, 4000A, 4200A, 5000A, 6000A |
| Long-time (overload) protection | From 25% to 110% of the current sensor tap rating | MIN (5 sec), INT (13 sec), MAX (27 sec) or custom value between 1 and 30 seconds. Delay is reverse I2t and defined by time to trip at 600% of the long-time pickup value. | |
| Short-time protection | From 150% to 1000% of the long-time pickup value. | Selectable constant or reverse I2t ramp with delays of .070, .100, .150, .200, .300, .400, .500, or .600 seconds. | Function can be defeated provided that the Instantaneous protection band is enabled.
Delay can be selected either as a fixed delay or reverse I2t. |
| Instantaneous protection | From 150 to 1200% of the long-time pickup value. | Trips breaker in less than .050 seconds. | Function can be defeated provided that Short-time protection is enabled. |
| Ground Fault protection | From 10% to 200% of the sensor tap rating, provided that this value does not exceed 1200A. Increments are of 5% of the sensor tap rating up to 100% of tap rating. Above 100% of tap rating, increments are in 10% of tap rating. | Selectable constant or reverse I2t ramp with delays of .100, .150, .200, .300, .400 or .500 seconds. | Function can be defeated
Delay can be selected either as a fixed delay or reverse I2t. |
| Phase Imbalance protection. | From 15% to 50% ratio of minimum /maximum phase current. | Between 1 and 90 seconds | Function can be defeated. |
| flashSAFE Instantaneous Pickup | Same as Instantaneous | Trips breaker in less than .050 seconds. | less than .050 seconds.
May be defeated. Must be lower than the previously entered instantaneous pickup. May be enabled even if instantaneous is defeated. |
| flashSAFE Ground fault pickup. | Same as Ground Fault | Fixed at .100 seconds w/ no I2t ramp | May be defeated. Must be lower than the previously entered ground fault pickup. May be enabled even if ground fault is defeated. |
