White Square D Homeline miniature circuit breaker, paddle actuator, plug-in mount, 3.1 in long

SQUARE D

SQUARE D HOM115CAFI Arc Circuit Breaker 15A 1 Pole

SKU CH-J9BG-B16QT

Protects 120 V single-phase circuits with 15 A combination Arc fault detection in a 1-pole plug-in Homeline breaker rated 10 kA AIR

  • Combination arc-fault protection detects dangerous arcs
  • 15 A rating suits standard branch circuits
  • Single-pole design fits one load-centre slot
  • Plug-in mounting enables quick panel installation
  • 10 kA interrupting rating handles high fault currents

HOM Series Arc Fault Breaker

This Square D HOM115CAFI is a 15 A single-pole combination arc fault circuit interrupter designed for Homeline load centres. It protects branch circuits in residential panels where arc detection is required by code.

120 V AC Plug-In Limitation

The breaker operates only on 120 V AC systems and carries no DC rating. Its plug-in mounting fits Homeline series panels with a 100 A frame size, so it cannot be used in panels that require bolt-on breakers or higher frame ratings.

10 kA Interrupting Rating

The maximum AIR of 10 kA at 120 V AC determines whether this breaker can safely clear the available fault current in a given installation. Circuits with higher prospective short-circuit current need a breaker with a larger interrupting rating.

Questions about this item

Should I pick the 15 A single-pole version or a different amp rating for my Homeline panel?

Choose the 15 A single-pole breaker when the branch circuit is wired for 15 amps; other amp ratings protect different wire sizes and are not interchangeable.

What does the 10 kA interrupting rating mean once the breaker is installed in my load center?

It means the breaker can safely clear a short-circuit current up to 10 kA at 120 V AC without damage, which covers typical residential fault levels.

Does the plug-in mounting work with any panel, or only Homeline load centers?

The plug-in design is keyed for Homeline series load centers only; it will not seat correctly in other manufacturers' panels.
