Programmer Secondary Disconnect (Breaker Side-N/A); Ak25 - ABB EntelliGuard AKD-5 Installation Manual

Programmer Secondary Disconnect (Breaker Side—N/A)
Programmer secondary disconnects are not provided on AKD5 legacy LVS breakers. If the customer
chooses to use the advanced features of the EntelliGuard ACB, the control wiring needs to be routed
from the LVS directly to the secondary disconnect landing points on the cassette assembly of the
EntelliGuard ACB cassette. Refer to the tables
that make up the 78-point secondary-disconnects. Ordering info given here:
Install Position Switch Actuator (Breaker Side)
Legacy Breaker

AK25

The position-switch actuator assembly for the AK25 should be mounted on the bottom plate of the
cassette assembly of the AK25 retrofill. The actual actuator assembly consists of two plates, one on the
top (top plate) and one on the bottom of the baseplate. The top plate of the actuator interfaces with the
breaker when it is racked in and the motion of the same is transferred to the bottom plate which
interfaces with the position switch lever on the legacy compartment.
Completing the racking in of the EntelliGuard breaker into the cassette corresponds to the end of stroke
of the position switch system in the compartment for AK25 in AKD-5 LVS.
