Description
The U2452B is an electronic component in the product category of IC Chips. It is a miniature circuit breaker manufactured by Schneider Electric. This circuit breaker is designed for use in residential and commercial applications. It is tested and listed according to UL Standard 489 and CSA Standard C22.2 No. 5-02 for molded case circuit breakers and enclosures.
The QOU miniature circuit breakers are unit-mount (lug/lug) thermal-magnetic circuit breakers. They provide a means to manually open a circuit and automatically open a circuit under overload or short circuit conditions. These circuit breakers feature common tripping of all poles and have a Visi-Trip® trip indicator. They can be flush-, surface-, or DIN rail-mounted and operate in any position. Additionally, QOU circuit breakers are fully tested, UL listed, and CSA certified for reverse connection without restrictive line/load markings.
Specifications and features
- Available for surface-, flush-, or DIN rail-mounted applications
- One-, two-, and three-pole constructions

- Measures 0.75 in. (19 mm) wide per pole
- Equipped with an internal crossbar for common tripping of all poles
- Available in various ampere ratings
- Constructed of a glass-reinforced insulating material for high dielectric strength
- Handle position indicates circuit breaker status
Application Scenarios
- One-pole QOU miniature circuit breakers rated 120/240 Vac are suitable for use on 120/240 Vac single-phase, three-wire or 208Y/120 Vac three-phase, four-wire electrical systems
- Two-pole QOU circuit breakers rated 120/240 Vac are suitable for use on 120/240 Vac single-phase, three-wire or 208Y/120 Vac three-phase, four-wire electrical systems (not suitable for 240 Vac delta systems)
- Two-pole QOU-H circuit breakers rated 240 Vac are suitable for use on 240 Vac delta and 240 Vac single-phase, two-wire systems
- Three-pole QOU circuit breakers rated 240 Vac are suitable for use on any system where the maximum phase-to-phase or phase-to-ground voltage is 240 Vac or less
