Information About QO370
The QO370 belongs to Schneider Electric’s QO Series, a widely used breaker family known for reliability in commercial, light industrial, and specialized three-phase installations. Its three-pole configuration supports balanced protection across all phases of a 240-volt system. The breaker supports wire sizes from 8 AWG to 2 AWG, offering versatility in conductor selection. Utilizing a thermal-magnetic trip mechanism, it provides long-time overload response and instantaneous short-circuit protection, supported by a 10 kA interrupt rating. Its compact form factor and plug-in/plug-on design streamline installation and replacement within compatible panelboards.
Key Features:
- 70A, 240V rating: Suitable for medium-capacity three-phase circuits.
- Three-pole construction: Provides coordinated protection across all phases.
- Thermal-magnetic trip unit: Protects against overloads and short-circuit events.
- 10 kA interrupt rating: Supports safe fault clearing in commercial settings.
- Box-lug terminals: Accept 8–2 AWG conductors for flexible wiring.
- Plug-In/Plug-On mounting: Enables fast, secure installation in QO panels.
- Compact dimensions: 2.91 in L × 2.25 in W × 3 in H for space-efficient panel layouts.
- Rated for 40°C environments: Ensures dependable operation under standard ambient conditions.
The QO370 delivers the reliability and precision required for molded case protection in three-phase commercial and industrial systems.
