Load Shedding and Reconnection Parameters
Load shedding and reconnection parameters can be set according to the power or the current flowing
through the circuit breaker. Load shedding is carried out by a remote computer via the communication
network or by an M2C or M6C programmable contact.
Indication Option via Programmable Contacts
The M2C (two contacts) and M6C (six contacts) programmable contacts may be used to signal
threshold overruns or status changes. They can be programmed using the keypad on the Micrologic P
and H trip units or remotely using the communication network. These contacts are required to obtain
data from the protective relay functions on Type P and Type H trip units.
