QBM22125TN - 125 Amp Circuit Breaker Description

QBM22125TN - 125 Amp Circuit Breaker

The QBM22125TN is a 2-pole, 125-amp thermal magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection for 120/240VAC electrical distribution systems. Built with a non-interchangeable trip unit, this breaker delivers consistent, factory-set protection that helps maintain system reliability in commercial and industrial applications. Featuring lug terminals on the line side and 1/4-20" studs on the load side, the QBM22125TN is well suited for installations requiring secure, high-current connections. Its compact footprint also makes it an excellent choice when dependable circuit protection is needed without sacrificing valuable panel space.

Whether you're replacing an existing breaker or maintaining electrical equipment, the QBM22125TN offers the performance and durability expected from a thermal magnetic molded case circuit breaker. The combination of thermal overload protection and instantaneous magnetic trip response helps safeguard electrical equipment from potentially damaging fault conditions while supporting safe, reliable operation.

Key Features and Benefits

  • 125 Amp continuous current rating for higher-capacity electrical distribution applications.
  • 2-pole configuration for protecting 120/240VAC circuits.
  • Thermal magnetic trip mechanism provides protection against both overloads and short circuits.
  • Factory-installed non-interchangeable trip unit delivers consistent, calibrated protection.
  • 10k A.I.C. interrupting rating at 120/240VAC helps safely interrupt available fault currents within its rated capacity.
  • Line-side lug terminals simplify incoming conductor connections.
