Square D QOU225 - 25 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Designed by Square D, the QOU225 is a 2-pole bolt-on molded-case circuit breaker rated at 25 amps and 240 volts. Built for dependable branch circuit protection, this device quickly responds to faults while staying steady under normal load, helping keep your panel operating smoothly. Key advantages that set the QOU225 apart - Secure bolt-on mounting: a rigid, vibration-resistant bus connection that maintains consistent protection even in installations subject to movement or vibration. - Thermal-magnetic trip unit: a precise thermal element handles overload conditions with repeatable timing, while the magnetic element delivers fast disconnection on short circuits, reducing damage and downtime. - Dual-pole protection: both conductors disconnect simultaneously to prevent floating voltages and ensure a safe, code-compliant shutoff. - Exact compatibility: designed to pair with matching OEM load centers and panelboards, delivering reliable fit, correct trip characteristics, and straightforward replacement. - Versatile application range: suitable for residential panels, commercial installations, and light industrial setups where dependable branch-circuit protection is essential. Who benefits most - Homeowners upgrading a panel to add or reconfigure a dedicated 25A circuit. - Facility managers replacing aging breakers in existing Square D panelboards to restore reliable protection. - Electricians installing new circuits in small to mid-size commercial or light industrial environments that require robust, code-compliant breakers. Why this matters in real-world use - Consistent protection under variable loads: the thermal-magnetic mechanism provides stable trip behavior across a range of operating conditions, reducing nuisance trips and enhancing safety. - Long-lasting reliability in panel assemblies: bolt-on mounting minimizes movement-induced connection issues, preserving a solid electrical connection over time. - Clear compatibility pathway: selecting the QOU225 ensures you’re using a breaker designed to work in tandem with compatible Square D panelboards, helping to avoid fitment or performance surprises during installation.
