1 . Curve accuracy applies from –20°C to +55°C ambient . For possible continuous Ampere derating for ambient above +40°C, refer to Eaton . Temperatures above +85°C cause an overtemperature protection trip .

2 . Application frequency is 50/60 Hz .3 . There is a memory effect that can act to shorten the Long Delay . If the breaker trips on a

Long Delay overload and is quickly reset, the memory capacitor will still have charge and a subsequent overload will cause the breaker to trip in a shorter time than normal . The amount of time delay reduction is inverse to the amount of time that has elapsed since the previous overload . Approximately five minutes is required between overloads to completely reset memory .

4 . The right portion of the curve is determined by the interrupting rating of the circuit breaker .5 . The left portion of the curve is shown as a multiple of the Long Delay Setting

(Long Delay Pickup = 115% of Ir) . Range is 110–120% .6 . Total clearing times shown include the response times of the trip unit, the breaker opening,

and the interruption of the current .7 . The Short Delay Pickup has nine settings/positions: 2–8, 10, and 12 .For high fault current levels, an additional fixed Instantaneous Override is provided .

Instantaneous Override tolerance is +/– 20% . The Instantaneous Override pickup value (Ii) is a multiple of the breaker sensor rating (In) . The Instantaneous Override has precedence over a SDPU . When Rated Amps (Ir) is set to the maximum (position H), then both the SDPU and the Instantaneous Override pickup are equivalent . Therefore, the breaker will trip on Instantaneous Override . In = 250A Instantaneous Override (Ii) = 28X(In) In = 400A, 600A, 630A Instantaneous Override (Ii) = 12X(In)

otese:N

1 . The Maintenance Mode feature must be ENABLED for these curves to apply, when in Maintenance Mode .

2 . The Maintenance Mode is Enabled locally by turning the Maintenance Mode/INST dial to the 2 .5X or 4X position, or via remote signal . Enabling the Maintenance Mode via remote signal sets the pickup to 2 .5X regardless of Maintenance Mode/INST dial position .

3 . The end of the curve is determined by the interrupting rating of the circuit breaker .4 . Total clearing times shown include the response times of the trip unit,the breaker opening,

and the interruption of the current .5 . Nominal Values (Pickup) (Tolerance is ±15%) 2 .5X In, 4X In, 6X In, 7X In, 8X In, 10X In, 12X In .6 . These curves are comprehensive for the complete family of Series G L-Frame electronic

breakers, including all frame sizes, ratings, and constructions . The total clearing times shown are conservative and consider the maximum response times of the trip unit, the circuit breaker opening, and the interruption of the current in worst case conditions, such as maximum rated voltages, single-phase interruption, and minimum power factor . Faster clearing times are possible depending on the specific system conditions .

7 . For L-Frame breakers with 250A sensors (In = 250A), an INST setting of 12 is equal to 28X (7000A) .

8 . Contact Eaton for additional information .

This feature allows enabling of the maintenance mode remotely by applying 24 Vdc to the yellow (+) and black (–) wires that exit the left hand side of the breaker . The maintenance mode settings that is enabled is the 2 .5X setting .

There are two indicators that can verify that the trip unit has been remotely activated/enabled into the maintenance mode feature:

A . The blue LED (MM) located on the top left side of the trip unit will light .

AND/OR

B . The relay output is provided by three wires exiting the left hand side of the breaker: blue = C, red = NO, black = NC . The relay will change state when the maintenance mode is remotely enabled .
