Description

Miniature Circuit Breaker 40A 2 Pole 120/240V AC 10kA Bolt-On

Features

Integrated with the patented Visi-Trip system, a high-visibility red mechanical indicator snaps into view the moment the breaker trips due to a fault. This allows maintenance staff and facility managers to instantly identify the source of power loss in a crowded, multi-row panelboard, drastically reducing diagnostic time and speeding up the restoration of critical services.
Providing 10kA of interrupting capacity at 120/240V AC, this common-trip 40A breaker is the standard for powering mid-sized loads such as commercial water heaters, small HVAC air handlers, and commercial kitchen machinery. The simultaneous opening of both poles ensures that if one leg of the circuit faults, the entire power supply is disconnected, preventing dangerous back-feeding and protecting your three-phase or split-phase equipment from damage.
As part of the world-class QO family, the QOB240 is built with a proprietary pressure-plate wire terminal and a quick-make, quick-break mechanism that extends the life of the internal contacts. Choosing an authentic Schneider Electric component ensures full UL Listing and CSA certification, guaranteeing that your electrical infrastructure remains code-compliant and your property insurance requirements are fully satisfied.
