Ekip Multimeter module
The Ekip Multimeter is a remote displaying unit on the front of the switchgear and is equipped with a
touchscreen display.
It can be installed in combination with Ekip Dip, Touch, Hi‐Touch, G Touch, and G Hi‐Touch trip units, with
which it communicates via Local Bus. It must be powered independently of the trip units to which it is
connected and can be powered in AC at 105...265 V AC/DC, or DC at 21.5...53 V DC.
IMPORTANT: AC and DC power supplies cannot be present at the same time.
The following table lists the electrical characteristics of the module:
Power supply voltage
Frequency
Power input
Inrush current
21.5...53 V DC
-
Maximum 10W
Maximum 2 A for 20 ms
105...265 V AC/DC
45…66 Hz
Maximum 10 VA/W
Maximum 2 A for 20 ms
One trip unit can communicate with a maximum of four Ekip Multimeters. On the other hand, the module can
be connected to only one trip unit.
In addition, the module makes available an auxiliary voltage of 24 V DC, which can be used to power the
trip unit. If the trip unit is powered through Ekip Multimeter, the power supply must be applied directly on the
terminal box of the circuit-breaker: in fact the Ekip Multimeter is sized in order to supply only the trip unit,
and therefore it is may be unable to deliver enough power to supply an Ekip Supply module and any other
electronic accessories connected to the terminal box.
In case of connection to an Ekip Touch, Hi-Touch, G-Touch, and G Hi-Touch trip unit, as well as displaying the
measurements, the module also allows you to set parameters and protection thresholds.
For the Local Bus (communication lines W3 and W4) and the auxiliary output power (24Vout L+ and - signals),
Belden 3105A or equivalent cables must be used with a maximum length of 15 m. The shield of the cables
must be connected to ground on both sides of the connection.

External neutral
This is a current sensor for the neutral pole outside the circuit-breaker.
It is provided only for three-pole circuit breakers. It allows protection of the neutral to be implemented through
the connection to the Ekip trip unit. It is supplied on request.
Further information on the connection of the external neutral is available on the website http://www.abb.com/

Contacts Ekip AUP
The communication modules are always supplied with dedicated Ekip AUP auxiliary position contacts. In
case of a withdrawable circuit-breaker, the Ekip AUP contacts give the signal of moving part racked-in/out
from the fixed part.
The assembly assures that the position signalling is given also with the moving part withdrawn.
IMPORTANT: in case of multiple communication modules, only one can be connected
to the Ekip AUP contacts.

Ekip RTC contact
The communication modules are always supplied with an Ekip RTC auxiliary contact, which gives to the trip
unit the signal indicating that the circuit-breaker is ready to receive a close command.
