Square D CH225 2-pole Circuit Breaker 25 Amp 120/240V

Product Description

The SQUARE D CH225 is a 2-pole, plug-on circuit breaker rated for 25 amps at 120/240 volts AC, designed for use in residential and light commercial load centers. It provides overcurrent protection with a 10 kiloamp interrupting rating, making it suitable for branch circuit applications where reliable fault protection is required. The plug-on mounting design allows for direct installation into compatible load centers without additional hardware. Licensed electricians install this breaker as part of panel upgrades, new construction wiring, or branch circuit additions.

This breaker is intended for load center installations in residential and light commercial settings. It handles branch circuits supplying 240-volt loads such as appliances, HVAC equipment, and subpanels, as well as 120-volt circuits when used in a tandem configuration. It accepts wire sizes from 14 to 8 AWG for standard applications and 14 to 10 AWG depending on configuration, accommodating a range of conductor sizes common in residential branch wiring.
