Square D QOB215 Mini Circuit Breaker 15A 2 Pole 120/240VAC 10kA Bolt-On Mount

Description

Features

• The Schneider Electric (Square D) QOB215 is a 15-Amp, 2-pole thermal-magnetic circuit breaker. The "B" in the part number signifies "Bolt-on." While it looks almost identical to a standard QO breaker, it features a mounting screw that physically bolts the breaker to the panel's bus bar. This design is the standard for Canadian commercial and industrial panelboards (like the NQ series), where a permanent, vibration-resistant connection is required.
• Rated for 15 Amps at 120/240V AC, this 2-pole breaker is designed to protect dedicated 240V loads or 208V single-phase loads. In a Canadian commercial setting, you'll typically find the QOB215 protecting small HVAC units, baseboard heaters, or specialized industrial equipment that requires two hot legs of power.
• Like all premium Square D breakers, the QOB215 features the Visi-Trip™ indicator. When the breaker trips, a high-visibility red flag appears in a window on the face of the breaker. This allows a building manager or electrician to scan a panelboard containing dozens of breakers and instantly identify which circuit has faulted, significantly reducing downtime.
• The QOB215 has a standard 10kA (10,000 AIR) interrupting rating. This ensures the breaker can safely clear a short circuit without catastrophic failure. For environments with higher available fault currents, there are "high-interrupt" versions (QOB215VH), but the standard 10kA model is the workhorse for the majority of Canadian commercial installations.
• The internal mechanism is designed for a fast "snap" action during both manual operation and automatic tripping. This Quick-Make, Quick-Break design minimizes internal arcing, which preserves the life of the contacts and ensures the breaker performs reliably for decades, even in high-demand Canadian industrial environments.
