Description
QOU unit mount miniature circuit breakers (cable-in/cable-out) are ideal for OEM applications. QOU breakers are one, two or three pole thermal magnetic circuit breakers which provide overcurrent protection and switching on ac and dc systems. These circuit breakers have an over center, trip-free toggle mechanism with quick-make, quick break action and positive handle indication. They also have VisiTrip trip indication, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit. These QOU miniature circuit breakers can be DIN rail mounted, surface mounted or flush mounted using mounting feet. This two pole QOU miniature circuit breaker is rated as 20A, 240 VAC. This circuit breaker provides 10 kA breaking capacity. A full line of accessories are available for these circuit breakers. The slotted box lugs will accept one 14 AWG to 2 AWG copper or aluminum wire. This circuit breaker has a maximum height of 4.05 inches, a maximum width of 1.5 inches and maximum depth of 2.95 inches. QOU circuit breakers are UL Listed and CSA Certified.
Features
- Featuring an incredibly flexible "unit-mount" chassis, this 2-pole miniature circuit breaker can be DIN rail-mounted, surface-mounted, or flush-mounted utilizing specialized mounting feet. This makes it an invaluable, adaptable asset for original equipment manufacturers (OEMs) and commercial panel builders who need a single, reliable component that fits varied enclosure architecture without buying dedicated panel hardware.
- Engineered with an expansive voltage profile, this 20A thermal-magnetic breaker operates flawlessly on 120/240V AC networks as well as 48V DC infrastructure. This dual-system compatibility allows maintenance engineers to standardize on a uniform circuit protection model across standard building lines, HVAC components, and low-voltage DC auxiliary battery banks.
- Built with versatile, slotted box lugs on both the line side and load side, this standalone breaker handles direct cable-in/cable-out point-to-point wiring configurations. It eliminates the need for expensive, specialized distribution busbars or loadcentre structures, allowing for quick, isolated sub-circuit installation directly adjacent to standalone industrial control machinery.
- Equipped with Square D's patented Visi-Trip visual window indicator, a high-visibility mechanical red flag pops into view the exact moment the breaker interrupts a fault. This instantly differentiates a tripped breaker from one that has been manually turned off, significantly reducing plant diagnostic labor and helping field operators safely isolate and resolve downstream faults faster.
- Boasting a robust 10 kA short-circuit current rating (kAIC) at 120/240V AC and a 5 kA rating at 48V DC, this breaker delivers high-tier safety suppression against sudden short circuits. The glass-reinforced thermoset composite housing provides high dielectric strength and structural containment, protecting delicate nearby instrumentation from catastrophic thermal-magnetic blast energies.
