Square D QOB2100 Mini Circuit Breaker 100A 2-Pole 120/240V AC 10kA Bolt-On Mount

Description

Features

• The QOB2100 features a secure bolt-on connection designed specifically for NQ and NQOD panelboards, providing a permanent, vibration-proof attachment to the bus bar. This mechanical fastening eliminates the risk of "arcing at the bus," a common failure point in high-vibration industrial environments, ensuring your critical circuits remain energized without intermittent power flickers.
• Providing a robust 100A capacity at 120/240V AC, this dual-pole breaker is engineered to protect high-wattage equipment like large air handlers, water heaters, and industrial motors. By monitoring both "hot" legs simultaneously, it provides a common trip mechanism that ensures if one pole faults, both are disconnected, preventing dangerous "single-phasing" conditions that can burn out expensive three-phase motors.
• Featuring Schneider Electric s exclusive Visi-TripTM technology, a highly visible red mechanical indicator snaps into view the instant the breaker trips. This allows facility electricians to identify the faulted circuit across a crowded electrical room at a glance, significantly reducing troubleshooting downtime and getting your operations back online faster.
• As part of the industry-leading QO family, the QOB2100 is the gold standard for commercial distribution, designed for seamless integration into NQOD and NQ square-bus interiors. Its compact 1.5-inch width allows for high-density circuit placement, giving you the power of a 100A feed without sacrificing excessive rail space in your enclosure.
