Available Settings

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.
