Description
Built to protect circuits against overloads and short circuits, the Siemens EQ9684 is a 2-pole molded case circuit breaker rated 175A at 120/240VAC. Its interrupting rating is 22kAIC at 240V. The EQ frame uses plug-on mounting and lug terminals. The fixed thermal magnetic trip provides long-time and instantaneous protection. This single-phase breaker accepts conductors from 3/0 AWG to 250 MCM.Specifications

Product FAQs
7 answersIs the Siemens EQ9684 adjustable for a lower circuit current?
The Siemens EQ9684 has a 175A rated current and a fixed trip. Select it where that rating meets the circuit's protection requirements, rather than relying on an adjustable trip setting.
What voltage, phase and pole requirements should I check before selecting this breaker?
This breaker is rated 120/240VAC for single-phase use and has two poles. Check the circuit voltage, phase and required pole count when selecting it.
How does the 22kAIC interrupting rating affect selection?
The interrupting rating is 22kAIC at 240V. At that voltage, the available fault current at the installation point must not exceed this rating.
How does the thermal-magnetic trip protect the circuit?
The thermal-magnetic trip includes long-time and instantaneous functions. The thermal element responds to sustained overloads, while the magnetic element responds rapidly to short-circuit current.
What conductor sizes can I terminate at the breaker?
The lug terminals accept conductors from 3/0 AWG through 250 MCM. Choose a conductor within that range that also meets the circuit's ampacity requirements.
Does plug-on mounting describe the wire connection too?
No. Plug-on describes the breaker mounting method, while lugs are used for conductor terminations. Account for the mounting method and conductor terminations separately when planning installation.
What dimensions should I use when planning the breaker layout?
The breaker is 3.18 in high, 4.00 in wide and 2.50 in deep. Use all three dimensions to account for the space occupied by the breaker in the layout.
