Square D CH115 1-pole Circuit Breaker 15 Amp 120/240V

Product Description

The SQUARE D CH115 is a single-pole, plug-on circuit breaker rated at 15 amps and 120/240 volts AC. It provides overcurrent and short-circuit protection within a load center panelboard. With a 10 kiloamp interrupting rating, it handles high-fault-current events without compromising panel integrity. The plug-on mounting style allows for fast, tool-free installation into compatible load center bus bars. This breaker accepts wire sizes from 14 to 8 AWG, covering the range of conductors typically used on standard 15-amp branch circuits. Licensed electricians install this component during new construction, panel upgrades, or circuit additions.

The CH115 is suited for residential and light commercial load center applications where a 1-pole, 15-amp branch circuit breaker is required. Typical uses include lighting circuits, receptacle circuits, and small appliance branch circuits. Its plug-on design is intended for load center cabinets that accept the CH-style breaker footprint. It operates on 120/240 volt AC systems and is appropriate for single-phase distribution panels in residential dwelling units and commercial service panels of similar configuration.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always shut off the main breaker and verify the bus bars are de-energized before handling any breaker or panel component. Confirm wire size and circuit load requirements match the breaker rating before energizing. Do not exceed the conductor size range or current rating specified for this breaker.
