QOU370 - 70 Amp Circuit Breaker

QOU370 - 70 Amp Circuit Breaker

Make sure your electrical system stays safe and visible with the Schneider Electric QOU370 circuit breaker. Designed for both residential and commercial switchboard panels, plus light industrial distributions, this 3‑pole, 70 Amp breaker delivers reliable protection at up to 240 VAC and supports up to a 10 kA interrupt rating. Equipped with thermal‑magnetic trip technology, it responds instantly to short circuits while tolerating overloads before tripping. When a trip occurs, the built‑in VisiTrip indicator gives a clear visual signal – helping you identify the issue quickly and minimize downtime.

Key Features and Benefits

• Dual‑action overcurrent protection: Fast tripping for short circuits, delayed action for overloads—combining safety and flexibility.
• High-rated interrupt capacity: Supports up to 10,000 A fault current at 240 VAC without compromising safety.
• Easier installation: Unit‑mountable with slotted box lugs on both line/load ends—suitable for DIN‑rail, surface or panelboard mounting.
• Trip indicator for fast diagnostics: VisiTrip indicator makes it simple to spot a tripped breaker at a glance.
• Resistance to harsh environments: Designed to perform well in high humidity or salty air—it won’t give out under pressure.
