Square D CHT1515 Twin Circuit Breaker 15A Plug-on

Product Description

The SQUARE D CHT1515 is a twin tandem circuit breaker designed for plug-on installation in residential and light commercial load centers. Rated at 15 amps per pole with a 120/240 volt AC rating, it provides thermal magnetic overcurrent protection across two circuits while occupying a single breaker slot. With a 10 kiloamp interrupting rating, the CHT1515 handles fault currents typical of standard panel applications. Licensed electricians install this breaker during new construction, panel upgrades, or circuit additions where space in an existing load center is limited.

The CHT1515 is suited for residential and light commercial electrical panels where two 15-amp, 1-pole circuits must be accommodated within a single slot. Its plug-on mounting style allows direct installation without additional hardware. The breaker is compatible with both CTL and non-CTL CH load centers, making it a practical choice when expanding circuit capacity in existing panels. Acceptable wire sizes range from 14 to 8 AWG using copper or aluminum conductors.

Key Features

• Twin tandem configuration provides two independent 15-amp circuits in one breaker slot
• Thermal magnetic trip mechanism protects against both overload and short-circuit conditions
• 10 kiloamp interrupting rating suitable for residential and light commercial panels
• Plug-on mounting for straightforward installation in compatible load centers
• Accepts 14 to 8 AWG copper or aluminum wire
• UL 489 listed for branch circuit overcurrent protection

Compatibility

Compatible with CTL and non-CTL CH load centers as specified by the manufacturer.

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 panel is de-energized before handling any breakers or bus connections. Confirm the load center is a compatible CH-type panel before installation. Do not exceed the wire size and conductor material ratings specified for this breaker.
