Product FAQs
8 answersWhat panelboards are compatible with the QOB2601201 circuit breaker?
This bolt-on breaker is specifically designed for installation in Square D NQ and NQOD series panelboards. It is not compatible with standard QO residential load centers.
How is the QOB2601201 secured to the panel bus?
It utilizes a bolt-on mounting configuration. The breaker fastens directly to the panelboard bus bar using built-in screws, ensuring a secure, vibration-resistant connection required in many commercial and industrial environments.
Is this breaker rated for direct current (DC) systems?
Yes. While primarily used for 120/240VAC applications, this breaker is also rated for use on 48VDC systems with a 5kA interrupting capacity.
What are the acceptable wire sizes for the terminals on this breaker?
The factory-installed box lugs accept wire gauges from 8 AWG up to 2 AWG. The terminals are rated for use with both copper and aluminum conductors.
What does the 1201 suffix mean in the QOB2601201 part number?
The 1201 suffix indicates that this breaker comes with a factory-installed auxiliary switch. This provides a 1B (normally closed) contact used for remote signaling or status monitoring of the breaker.
How does the thermal-magnetic trip mechanism function on this breaker?
The thermal component provides a delayed trip (long-time) to protect against sustained overloads, while the magnetic component provides an instantaneous trip to quickly clear severe short circuits.
Can I use the QOB2601201 to replace a standard QO260 breaker?
No. Although they share the same electrical ratings, QOB breakers are bolt-on and QO breakers are plug-on. You must use the mounting style that matches your specific panelboard interior.
Does this breaker include a tripped status indicator?
Yes, it features the Square D Visi-Trip indicator. When the breaker trips due to an overload or short circuit, a highly visible red indicator appears in the window to help quickly identify the faulted circuit.
