Product FAQs
7 answersWhat panelboards are compatible with the QOB130EPD1201 breaker?
This bolt-on circuit breaker is designed exclusively for Square D NQ and NQOD panelboards. It is not compatible with standard QO load centers or Homeline panels, which require plug-on connections.
What is the difference between an EPD breaker and a standard GFI breaker?
An EPD (Equipment Protection Device) features a 30mA ground-fault trip threshold designed to protect machinery and heat tracing from low-level faults. In contrast, a standard GFI breaker has a highly sensitive 5mA threshold intended for personnel protection.
What does the 1201 suffix indicate on the QOB130EPD1201 catalog number?
The 1201 suffix means this breaker comes with a factory-installed auxiliary switch featuring 1B (Normally Closed) contacts. This allows for remote monitoring of the breaker status.
How is the QOB130EPD1201 installed into a panelboard?
This breaker utilizes a bolt-on mounting mechanism. It fastens directly to the panelboard bus bar with a screw, providing a secure, vibration-resistant connection ideal for commercial and industrial applications.
How is the neutral connection handled on this ground-fault breaker?
The QOB130EPD1201 is equipped with a pigtail neutral wire. This pigtail must be connected directly to the panel neutral bar to ensure the ground-fault sensing circuitry operates correctly.
How can I tell if the QOB130EPD1201 has tripped?
This breaker includes the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent, short circuit, or ground fault, the handle moves to a center position and a bright red indicator appears, making it easy to spot in a crowded panel.
What if my panel requires an interrupting rating higher than 10kAIC?
The QOB130EPD1201 provides a standard 10kAIC rating at 120VAC. If your system fault current requires a 22kAIC rating, you must specify a QOB-VH series breaker, such as the QOB130VHEPD, and verify if the 1201 auxiliary switch configuration is available for that model.
