Description

QOU Miniature Molded Case Circuit Breakers are intended for use in residential and commercial applications. They are used for overcurrent protection and switching on both AC and DC electrical systems. These breakers provide a means to manually open a circuit using the interally magnetic strips. 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 three pole QOU miniature circuit breaker is rated as 15A, 240VAC. This circuit breaker provides 10 kA breaking capacity. QOU circuit breakers have been verified to adhere to their datasheet specifications by UL and CSA.

Features

Featuring an incredibly flexible "unit-mount" chassis, this 3-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 15A thermal-magnetic breaker operates flawlessly on 3-phase systems up to 240V AC. This dedicated three-pole framework ensures that an electrical fault or minor overload on any single phase instantly trips all three poles simultaneously, isolating the entire circuit to protect delicate downstream three-phase motors, pumps, and heating elements from single-phasing damage.
Boasting a robust 10 kA short-circuit current rating (kAIC) at 240V AC, 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.
