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:

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 |

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 |
