ABB | SACE Emax 2
- 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/
abblibrary/DownloadCenter/, in particular in the kit sheets:
• 1SDH001000r0506 for circuit breakers E2.2.
• 1SDH001000r0515 for circuit breakers E4.2 and E6.2.

6 - Ekip Com Actuator

Ekip Com Actuator is an accessory module which allows SACE Emax 2 circuit-breakers to be opened and
closed remotely.
The module is installed on the front of the circuit-breaker, in the accessories area.
For references about the connection and terminals, please consult document 1SDH000999r0501 and
1SDH001000r0501
The Ekip Com Actuator module is supplied on request and is compatible with all Ekip Touch Trip units when
the Ekip Com or Ekip Link modules are installed.

7 - 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The assembly assures that the position signalling is given also with the moving part withdrawn.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.
Further information on assembling Ekip AUP modules and contacts is available on the web site http://www.
abb.com/abblibrary/DownloadCenter/, in particular in the kit sheet 1SDH001000r0811.

8 - Ekip RTC

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.
Further information on the assembly of the Ekip RTC contact is available on the web site http://www.abb.
com/abblibrary/DownloadCenter/, in particular in the kit sheet 1SDH000999r0614.
