Overcurrent protection settings
The parameters for the basic functions are adjusted with rotary coding switches.
Various additional functions are adjusted with slide switches.
The settings for the additional function "load monitoring" can be adjusted via:
- the alphanumeric display
- TD400 and the software "powerconfig"
- the COM modules with a PC with the software “powerconfig” installed
These settings can only be adjusted if the trip unit is activated, i.e. it must be connected to an external 24 V DC voltage supply
(UL Listed Class 2).
Protective functions
Overload protection – L-tripping (page 9-11)
Short-time delayed short-circuit tripping – S-tripping (page 9-11)
Instantaneous short-circuit tripping – I-tripping (page 9-12)
Ground-fault tripping – G-tripping (page 9-12)
Neutral conductor protection – N-tripping (page 9-13)
Load monitoring (load restore / load shedding) (page 9-13)
Leading signal for L-tripping (page 9-13)
Thermal memory can be switched On/Off (page 9-14)
Ground-fault protection modules (page 9-44)
Characteristics
The ranges shown in the following are only setting ranges of the respective parameters. Possible tolerance ranges are not included here.
Tolerance ranges are shown in the Easy TCC Time Current Curve Software. The characteristics apply to the circuit breaker version H-class,
480 V, frame size II, with ground-fault protection module.
L-tripping
S-tripping
Ground-fault tripping
NOTICE
Circuit breaker may trip.
If the trip settings are changed while the breaker is closed (and under load) the breaker may trip.
Adjust parameters only when the circuit breaker is in the open position.
The value 0.1 is set if the
