Schneider Electric QOB220 Mini Circuit Breaker 20A 2 Pole 120/240VAC 10kA Bolt-On Mount

Description

Features

• The Schneider Square D QOB220 is a 20-Amp, 2-pole, bolt-on thermal-magnetic circuit breaker. It is designed to provide overcurrent protection and switching on AC electrical systems. As a 2-pole breaker, it occupies two spaces in a panel and is used to protect 240V or 208V single-phase loads.
• The "B" in QOB stands for Bolt-on. Unlike the standard QO breakers that "plug" into a load center, the QOB220 features a physical screw-clamp terminal that bolts directly onto the bus bar of the panelboard. This provides a more secure, high-integrity mechanical connection, which is a requirement for many commercial and industrial specifications.
• Rated for 20 Amps, this breaker is the standard choice for heavy-duty branch circuits. It is commonly used to protect: HVAC equipment (small air handlers or condensers). Commercial kitchen appliances. Industrial lighting circuits. Small motors (pumps or fans).
• Like all Square D QO-family breakers, the QOB220 features the patented Visi-TripTM red indicator. When the breaker trips due to a fault or overload, a bright red flag appears in a window on the face of the breaker. This allows maintenance staff to identify the affected circuit at a glance in a dark or crowded electrical room.
• The QOB220 has a standard interrupting rating (AIR) of 10,000 Amps (10kA) at 120/240V AC. It is also available in "high-interrupting" versions if your specific panelboard is located in a high-fault current area (such as near a large utility transformer).
