Eaton AUX1A1BPK – Frequently Asked Questions

1) Which Eaton circuit breakers does the AUX1A1BPK auxiliary switch fit?
The AUX1A1BPK auxiliary switch is built for Eaton Series G molded case breakers in the EG- and JG-Frame, covered as Frame J-K. It mounts into the breaker's accessory cavity, so it is not a universal add-on: if your breaker is a different Eaton frame or another manufacturer's, this one will not seat correctly.
2) What does a 1A-1B contact configuration give me for breaker status monitoring?
One normally open contact and one normally closed contact, both following the breaker's on/off position. That gives you a signal either way: the A contact closes when the breaker is closed, the B contact closes when it is open. Enough to drive a remote indicator light, a PLC input, or an interlock circuit from a single switch.
3) Is the ABB Spec-Setter DPDT auxiliary contact a substitute for the Eaton AUX1A1BPK auxiliary switch?
No. The Eaton AUX1A1BPK is a molded case circuit breaker auxiliary switch built specifically for Eaton EG- and JG-Frame breakers in the Series G platform, with a 1A-1B contact configuration. The ABB Spec-Setter auxiliary contact is a DPDT contact for an ABB Spec-Setter safety switch, a different device entirely - a disconnect switch rather than a molded case breaker. If the status signal is coming off an EG- or JG-Frame breaker, the Eaton AUX1A1BPK is the part that mounts to it; the ABB unit is what you would use on a Spec-Setter safety switch.
4) Will an auxiliary switch take up extra space in my panel?
No. The Eaton Series G auxiliary switch mounts into the breaker itself rather than beside it, so it does not eat additional panel width. The accessory measures 3.5 in wide, 3 in in length/depth and 5.5 in high as packaged.
5) Do I need an auxiliary switch or a shunt trip for my breaker?
Different jobs. An auxiliary switch like the Eaton AUX1A1BPK only reports position, telling your panel or BMS whether the breaker is on or off through its 1A-1B contacts. It cannot operate the breaker. If you need to trip the breaker remotely from a fire alarm, e-stop or control signal, you want a shunt trip accessory instead. Many installs use both in the same EG- or JG-Frame breaker.
6) Can I add this auxiliary switch to a breaker that is already installed?
Yes, it is a field-installable accessory for EG- and JG-Frame Series G breakers, which is why it is commonly used for retrofit and replacement of Series G breaker accessories. The breaker has to be de-energized and removed from service to open the accessory cover and seat the switch.
7) What part number do I order for the Eaton EG-/JG-Frame auxiliary switch?
Order Eaton AUX1A1BPK. That is the Series G auxiliary switch with the 1A-1B contact arrangement for EG- and JG-Frame breakers, and it is the only configuration offered under this model.
