Product description
Shipping
Protect critical circuits with precision using the Square D QBM22125TN, a bolt-on, 2-pole circuit breaker designed for reliable 240V protection. With a 125A rating and a 10kA interrupting capacity, this breaker is built to handle fault currents while keeping your panel running smoothly.
Key specifications
- Amperage: 125 A
- Poles: 2-Pole
- Voltage: 240 V
- Interrupting rating: 10 kA
- Mounting style: Bolt-On
- Part number: QBM22125TN
Why this breaker stands out
- Designed for maintenance, retrofit, and replacement in compatible Square D panel systems, enabling you to restore protection without a full panel upgrade.
- Bolt-On mounting delivers a secure, stable connection ideal for installations subject to vibration or movement.
- 125A capacity provides robust protection for larger branch circuits or feeders while accommodating practical current needs in commercial or sizable residential applications.
- 10kA interrupting capacity helps safely clear high-energy faults, reducing the risk of damage downstream and downtime.
Compatibility and fit guidance
Before purchasing, verify compatibility by matching the part number: QBM22125TN. This unit is intended for Square D bolt-on QBM panel configurations. If your panel does not support bolt-on QBM breakers, this model may not be suitable for your setup.
Ideal use cases
- Replacing a worn or tripped breaker in retrofit projects where the panel accepts Square D QBM bolt-on devices.
- Feeder protection upgrades on 240V circuits in medium to larger electrical installations.
- Maintenance scenarios in service environments where rapid, reliable circuit protection is essential.
Installation tips and practical notes
- Keep the replacement aligned with the original part number (QBM22125TN) to maintain system compatibility.
- Handle the breaker carefully to preserve the mounting clip and bus connection alignment within the panel.
- Clearly label the circuit after installation to reflect 125A, 240V, and 2-pole protection for future service reference.
