Schneider Electric QOB115 Mini Circuit Breaker 15A 1 Pole 120/240VAC 10kA Bolt-On Mount

Description

Features

• The Schneider Square D QOB115 is a premium, single-pole 15-Amp circuit breaker designed for high-reliability commercial and industrial applications. Unlike standard plug-on residential versions, the "B" in QOB signifies a bolt-on connection, which physically secures the breaker to the panel bus bar with a screw. This ensures a permanent, vibration-resistant electrical contact that is mandatory in many data centers, hospitals, and industrial facilities.
• One of the most sought-after features of the QO line is the integrated Visi-TripTM indicator. When the breaker trips due to a fault, a high-visibility red mechanical flag appears in the handle window. This allows maintenance staff to identify the faulted circuit from across the room at a glance, drastically reducing downtime and troubleshooting effort in large, complex power distribution panels.
• The QOB115 features a sophisticated thermal-magnetic trip mechanism. It provides a time-delay for standard temporary surges (like when a device first powers on) but offers instantaneous protection against high-energy short circuits with a 10kA interrupting rating. This dual-stage defense protects your sensitive electronic equipment and prevents wire overheating that can lead to electrical fires.
• Designed with the space-saving 3/4-inch width standard, the QOB115 allows for a higher number of circuits in a smaller footprint compared to typical 1-inch industrial breakers. This compact design is ideal for modern control cabinets and PDU (Power Distribution Unit) applications where every inch of DIN rail or interior space is at a premium.
• The load-side terminal utilizes a high-quality box-style pressure plate designed to accommodate #14 to #8 AWG copper or aluminum conductors. This design ensures a more secure, gas-tight connection than simple "side-wire" screws, preventing the loose connections that are the leading cause of arcing and heat damage in commercial environments.
