PROTECT ION TR I P UNI TS
3/29
Supply The Ekip Touch/Hi-Touch protection trip unit is self-supplied through the current sensors and does not require an external supply for the basic protec- tion functions or for the alarm indication functions. The trip units for all the circuit-breakers start to power on from a minimum of 0.2 x In* and activate the indication functions, the ammeter and the dis- play. All protection settings are stored in a non-vola- tile memory that maintains the information, even without a power supply. An auxiliary supply can also be easily connected. In fact, the trip unit can be sup- plied by means of a galvanically isolated 24V DC auxiliary voltage with the following characteristics:
The Ekip Supply module can be connected to both DC and AC current power supplies to activate addi- tional functions such as: • using the unit with the circuit-breaker open; • using additional modules such as Ekip Signalling and Ekip Com; • connection to external devices such as Ekip Multi- meter; • recording the number of operations; • G protection with values below 100A or below 0.2 xIn*; • zone selectivity; • Gext and MCR protection functions.

The Ekip Touch/Hi-Touch are also supplied with a battery that enables the cause of the fault to be in- dicated after a trip. In addition, the battery enables the date and time to be updated, thus ensuring the chronology of events. When the Ekip Touch/Hi- Touch are active, they use an internal control circuit to automatically indicate that the battery is flat. Furthermore, when the unit is switched off a bat- tery test can be run by simply pressing the iTest key.
