Square D THQL2130 30A 2-pole Circuit Breaker 120/240V

Product Description

The SQUARE D THQL2130 is a 2-pole, 30-amp plug-in circuit breaker rated for 120/240 volts AC and designed for use in load center panels. It carries a 10 kiloamp (kA) interrupting rating, making it suitable for standard residential and light commercial overcurrent protection. The non-interchangeable design ensures it is installed only in compatible load centers, reducing the risk of misapplication. Quick-make and quick-break mechanisms provide consistent, reliable switching action, and a common trip bar ensures both poles open simultaneously on a fault. Easy-to-spot trip indication allows electricians and inspectors to identify a tripped breaker at a glance during panel service or inspection.

This breaker is used in residential and light commercial load center installations where a dedicated 30-amp, 240-volt or multi-wire branch circuit is required. Typical applications include circuits serving water heaters, dryers, air conditioning units, and similar double-pole loads. The 1-inch plug-in mounting format fits standard load centers that accept this form factor. Wire size compatibility spans 14 to 8 AWG, covering the conductors most commonly used on 30-amp branch circuits. Licensed electricians install this breaker during new construction, panel upgrades, or circuit additions.

Compatibility

Designed for use in load centers that accept 1-inch plug-in, non-interchangeable circuit breakers of this form factor. Accepts 14 to 8 AWG wire. Verify load center manufacturer specifications before installation to confirm compatibility.

Installation Notes

This breaker must be installed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify the absence of voltage before working inside the load center enclosure. Never install this non-interchangeable breaker in a panel that does not accept its specific form factor. Confirm conductor sizing and termination torque requirements per the load center manufacturer instructions and NEC Article 110.
