Information About QO270
The QO270 is a two-pole circuit breaker from Schneider Electric’s QO Series engineered for reliable branch-circuit protection in single-phase systems up to 120/240 volts. Its 70-amp rating supports higher-capacity residential and light commercial loads, while the thermal-magnetic trip unit provides balanced protection against overloads and short-circuit events. The breaker installs easily using a plug-on mounting system into QO load centers, and its box lug terminals accommodate wire sizes from 8 to 2 AWG for secure conductor termination. With a 10 kA interrupting rating and compact QO frame, the QO270 is well suited for environments requiring durable, space-efficient circuit protection.
Key Features
- 70-Amp High-Capacity Rating: Supports larger single-phase loads such as subpanels, HVAC equipment, and high-demand appliances.
- Thermal-Magnetic Trip Mechanism: Provides dependable response to both sustained overloads and instantaneous fault conditions.
- Two-Pole Construction: Ensures simultaneous disconnection of both legs of a 120/240-volt system for enhanced safety.
- Plug-On Mounting: Enables quick installation and secure engagement in Schneider Electric QO load centers.
- 10 kA Interrupt Rating: Effectively clears significant fault currents to protect wiring and connected equipment.
- Box Lug Terminations: Accommodates 8–2 AWG conductors for strong, reliable electrical connections.
- Compact QO Frame Design: Fits within standard panelboard spaces while maintaining robust electrical performance.
- 40°C Temperature Rating: Suitable for typical indoor electrical environments found in residential and light commercial buildings.
The QO270 delivers the reliability and precision required for protecting high-capacity 120/240-volt branch circuits in residential and light commercial electrical systems.
