How many auxiliary switches can be put in a Powerpact H or J Frame breaker?
Powerpact H and J breakers
For a 3-pole breaker:
One or 2 auxiliary switch accessories can be added. Each is a 1A1B form C contact. This gives total 2A2B.
In addition, these breakers will accept one SD (alarm) switch and one SDE (overcurrent trip alarm) switch.
NOTE: Installation of an SDx, NSX cord, BSCM, 24 Vdc Supply Terminal Block, or SDTAM accessory will affect the number of switches that can be installed. See attachment for details.
An HD or HG 2-pole breaker will accept only one aux switch and one SD alarm switch. An SDE is not possible.
