- Each etc-12 comes equipped with all protection bands which can be defeated if not needed.
- The etc-12 is available for all breaker frame sizes and current sensor primary ratings without the need for ratings plugs.
- The etc-12 can work with current sensors that have either a 1A or 200mA secondary rating. The unit auto detects the current sensor secondary rating based on the harness that is supplied with the particular sensors.
- The etc-12 is both eclectically and mechanically backwards compatible with all older generation etc-11, etc-11r and etc-11d trip units.
- The etc-12 can be secondary injection tested using Satin American’s original etc-PTS test set provided it is equipped with the PTS Adapter module.
- The time-current characteristics of any manufacturer’s solid state trip unit or electromechanical overload can be replicated with the etc-12. The following settings ranges are available:
| 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. | 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 |
| Long-time thermal memory | ON or OFF | N/A | |
| Ground-fault thermal memory | ON or OFF | N/A |
