Square D THQL2160 60A 2-pole Circuit Breaker 120/240V

Product Description

The SQUARE D THQL2160 is a 2-pole, 60-amp plug-in circuit breaker rated for 120/240 volts AC and designed for installation in residential and light commercial load centers. With a 10 kiloamp interrupting rating, it provides reliable overcurrent protection for branch circuits handling higher-load appliances such as dryers, ranges, water heaters, and HVAC equipment. The non-interchangeable plug-in design ensures it seats correctly in compatible load centers. Quick-make and quick-break mechanisms deliver consistent switching action, while a common trip bar ensures simultaneous disconnection of both poles on an overload or fault condition.

This breaker is intended for use in load center panelboards where a double-pole, 60-amp branch circuit is required. Typical applications include dedicated circuits for large appliances, electric heating equipment, and similar 240-volt loads in residential and light commercial settings. It accepts wire sizes ranging from 8 AWG to 3 AWG, covering the conductor gauges commonly used with 60-amp circuits. Licensed electricians install this breaker as part of panel upgrades, new construction wiring, or circuit replacement work.

Compatibility

Designed as a non-interchangeable plug-in replacement for compatible SQUARE D load center panelboards requiring a 2-pole, 60-amp breaker with 1-inch plug-in mounting.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify absence of voltage before installing or removing any breaker. Ensure conductor size falls within the 8 AWG to 3 AWG range specified for this breaker. Do not force the breaker into a load center for which it is not rated or listed.
