Note:Time/current characteristic curves for Engine Generator circuit breakers—voltages shown in curve headings are maximum at which the breaker may be applied. Interrupting capacity of individual breaker is tabulated on each curve.

Time Current Curves are engineering reference documents for application and coordination purposes only.For field testing molded case circuit breakers, refer to NEMA AB 4 guidelines.

End of Curve

Digitrip 310+ Circuit Breaker

Notes:

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

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

opening,and the interruption of the current.4. Nominal Values (Pickup) (Tolerance is ±15%)5. These curves are comprehensive for the complete family of Engine Generator L- and

M-Frames 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.

6. Contact Eaton for additional information.

This feature allows enabling of themaintenance mode remotely by applying24 Vdc to the yellow (+) and black (–) wires that exit the left hand side of the breaker. When energized, the maintenance mode setting that is enabled is the 2.5X setting.

There are two indicators that can verifythat the trip unit has been remotelyactivated/enabled into the maintenancemode feature:

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

AND/OR

B. The relay output is provided bythree wires exiting the left hand side of the breaker: blue = C, red = NO, black = NC. The relay will change state when themaintenance mode is remotely enabled by applying 24 Vdc to the yellow and black wires as described above.

M-Frames 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.

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.
