Square D QOU2155283 Miniature Circuit Breaker 15A 240V 2P

Product Description

The SQUARE D QOU2155283 is a 2-pole miniature circuit breaker rated for 15 amps at 240 volts AC. It provides overcurrent and short-circuit protection in residential and light commercial electrical distribution panels. The panel-mount design installs directly into a compatible loadcenter or panelboard. Ring tongue terminal connections secure wiring at each pole. Licensed electricians install this breaker as part of new panel builds or as a direct replacement when an existing breaker fails thermal or trip testing. At 0.75 pounds and compact dimensions, it handles cleanly in tight panel enclosures.

This breaker is suited for 240-volt, 2-pole branch circuits in residential and light commercial applications. Typical circuits include 240-volt appliance feeds, HVAC equipment disconnect branches, and similar double-pole loads requiring 15-amp protection. Panel-mount configuration means it snaps or bolts into the bus bar of the loadcenter rather than requiring a separate enclosure. Installation is performed at the panelboard with the main disconnect shut off and verified de-energized before the breaker is seated or wired.

Key Features

• 15-amp overcurrent rating with 240-volt AC capacity
• 2-pole configuration protects both legs of a 240-volt branch circuit
• Ring tongue terminal connection type for secure, reliable wire termination
• Panel-mount design for direct loadcenter installation
• Compact form factor at 4.9 x 3.7 x 2.1 inches fits standard panel layouts

Compatibility

Designed as an OEM-style replacement miniature circuit breaker for compatible Square D QOU-series loadcenters and panelboards that accept 2-pole, panel-mount breakers of this frame class.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Shut off the main panel disconnect and verify the bus bars are de-energized with a non-contact voltage tester before handling the breaker or any terminations. Do not exceed the breaker ampere rating when sizing branch circuit conductors. Confirm the breaker frame and mounting style are compatible with the target panelboard before seating the unit.
