QBHW2030S - 30 Amp Circuit Breaker

QBHW2030S - 30 Amp Circuit Breaker

The QBHW2030S is a 30-amp, 2-pole thermal magnetic circuit breaker with a bolt-on connection and a 120V AC shunt trip. It is rated at 22 kA at 120/240 VAC and is part of the QBHW Quicklag breaker type. The shunt trip is an important feature here. In a properly designed system, an external control circuit can electrically trip the breaker, which is useful for remote or emergency shutdown. The breaker is also HACR rated and rated at 40°C. Size is approximately 3.41 inches high, 3.0 inches wide, and 2.92 inches deep. If you're matching an existing breaker, take a minute to check more than the 30A rating. The QBHW type, two-pole design, bolt-on mounting, voltage, and interrupting rating all matter, and the 120V AC shunt trip needs to match the application's requirements as well.

Material Compliance and Certifications

• The QBHW2030S is HACR rated. Its supplied electrical specifications include a 30-amp rating at 40°C and a 22 kA interrupting rating at 120/240 VAC.
• For jobs that have specific certification or material-compliance requirements, check the markings on the breaker and the applicable manufacturer documentation. That is the best way to confirm any approvals or compliance requirements beyond the specifications listed here.

Where It Works Best

• This breaker is suited for compatible commercial and industrial electrical systems, HVAC-related circuits, machinery, control equipment, and panelboard applications that require its specific electrical characteristics. The 120V AC shunt trip makes the QBHW2030S particularly useful where the system is designed to trip the breaker through an external control circuit.
  
  For replacement work, QBHW2030S is the key part number to check, but don't stop there. Compare the 30A rating, two-pole, 120/240VAC rating, 22 kA A.I.C., bolt-on connection, and 120V AC shunt trip with the breaker being replaced and the equipment requirements. Electrical compatibility should always be confirmed before installation.
