Square D QOB210 Miniature Circuit Breaker 10A 240V 2 Pole

Product Description

The SQUARE D QOB210 is a 2-pole, bolt-on miniature circuit breaker rated for 10 amps at 240 volts AC. It provides overcurrent and short-circuit protection in branch circuit applications where reliable panelboard-mounted protection is required. The pressure plate terminal design accepts 14 to 8 AWG wire, making it suited for a range of commercial and light industrial branch circuits. Licensed electricians install this breaker as part of new construction wiring or as a direct replacement in existing panelboards. It carries UL Listing and CSA certification and is RoHS compliant.

The QOB210 is designed for use with Square D NQOD panelboards in commercial electrical distribution systems. The bolt-on mount secures the breaker firmly to the bus bar, reducing the risk of loosening under load or vibration. This breaker is commonly installed to protect HVAC equipment, lighting circuits, and general-purpose branch circuits requiring a 2-pole, 10-amp device in a bolt-on panelboard configuration.
