QOU140 - 40A Circuit BreakerQOU270 - 70 Amp Circuit Breaker

The Schneider Electric QOU270 is a 70 A, 2‑pole miniature circuit breaker engineered for dependable overcurrent protection in both AC and DC systems. Designed for 120/240 VAC and rated for up to 48 V DC, it offers a 10 kA interrupting capacity to safeguard homes, commercial settings, and OEM equipment. Its compact, unit‑mount configuration fits into tight enclosures without sacrificing safety or reliability.

Key Features and Benefits

• Efficient Overcurrent Safeguard: Shields your circuitry from fault conditions like short‑circuits and overloads, improving overall system safety.
• Dual‑Mode Protection: Combines immediate magnetic (instantaneous) and time-delayed thermal trip elements to cut faults fast while tolerating brief surges.
• Installation Flexibility: Unit‑mount design with slotted box‑lug terminals on both line and load ends accommodates AWG 12 to AWG 2/0 copper or aluminum conductors.
• Manual Circuit Control: Built‑in pull‑open feature allows manual disconnect for maintenance with added convenience.
• Space‑Saving Profile: Measures just 4.45 in × 1.5 in × 2.95 in, making it ideal for compact panels or retrofits.
