QBHW2050 - 50 Amp Circuit Breaker

QBHW2050 - 50 Amp Circuit Breaker

The QBHW2050 is a 50-amp, 2-pole thermal magnetic circuit breaker with a bolt-on connection. It is a QBHW/Quicklag-type breaker rated at 22kA at 120/240VAC and is intended for your compatible electrical equipment that requires these specifications. The thermal magnetic trip provides overload and short-circuit protection. This breaker is also HACR-rated, allowing it to be used in compatible heating, air-conditioning, and refrigeration applications when the equipment calls for a breaker with the same ratings. The QBHW2050 has a 40°C rating and measures 3.41 inches high, 2 inches wide, and 2.92 inches deep. For replacement jobs, it's worth checking more than the amp rating. A breaker can have the right amperage and still be wrong for the equipment. Compare the part number, QBHW type, two-pole configuration, voltage, interrupting rating, dimensions, and bolt-on mounting before installation.

Material Compliance and Certifications

• The information available for the QBHW2050 lists the breaker as HACR rated with a 40°C rating. No other material-compliance or certification information was included in the supplied specifications. If a particular approval or material standard is required for the job, check the breaker markings and applicable product documentation before use.

Where It Works Best

• The QBHW2050 circuit breaker is a fit for compatible electrical equipment that calls for a 50A, 2-pole QBHW bolt-on breaker rated for 120/240VAC. It may also be used in compatible HACR applications where its electrical ratings meet the equipment's requirements.
  
  This breaker can also make sense for maintenance or replacement work when you're matching an existing QBHW2050. Check the complete specifications first. Amperage alone isn't enough to determine whether two circuit breakers are interchangeable. The breaker type, number of poles, voltage, A.I.C. rating, mounting method, dimensions, and equipment requirements all need to line up.
