QBHW2070 - 70 Amp Circuit Breaker

QBHW2070 - 70 Amp Circuit Breaker

The QBHW2070 is a 70-amp, 2-pole Quicklag thermal magnetic circuit breaker for compatible 120/240 VAC electrical systems. It has a bolt-on connection and a 22 kA interrupting rating at 120/240 VAC. The breaker is rated at 40°C and HACR-rated.
If you're replacing an existing QBHW2070, this is the kind of breaker where the small details matter. It's not enough to match the 70-amp rating. You'll also want to check the two-pole configuration, QBHW type, voltage, AIC rating, and bolt-on connection against the equipment you're working with. At 3.41 inches high, 2 inches wide, and 2.92 inches deep, its dimensions can also help when comparing it with an existing breaker.

Material Compliance and Certifications

• The information provided for QBHW2070 identifies it as HACR-rated. No other material-compliance standards or certifications were included in the supplied specifications, so they aren't assumed here. If a particular approval or certification is required for the job, check the breaker documentation and the requirements of the equipment where it will be installed.

Where It Works Best

• The QBHW2070 makes sense when you're working with equipment that specifically calls for a 70A, 2-pole Type QBHW bolt-on breaker rated for 120/240 VAC. Its HACR rating also makes it compatible with heating, air-conditioning, and refrigeration equipment when those specifications are called for.
  
• For replacement work, compare the complete breaker specifications before making the match. QBHW type, 70A rating, two-pole, 120/240 VAC, 22 kA AIC, and bolt-on mounting should all meet the equipment requirements.
