Q2L3150H - 150 Amp Circuit Breaker

Q2L3150H - 150 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the small details can make all the difference. The Q2L3150H is a 150-amp, 3-pole thermal-magnetic circuit breaker with a 22k AIC rating at 240VAC. It's a Q2L-type breaker with a non-interchangeable trip unit and lug terminals on both the line and load sides. That last detail is worth checking closely, since terminal configuration is an important part of matching a replacement breaker to the existing setup. The Q2L3150H measures 6.5 inches high, 4.5 inches wide, and 3.13 inches deep, making the physical dimensions another useful point to compare with the breaker being replaced. For electricians, maintenance teams, and facility managers who keep compatible legacy equipment in service, this breaker provides the specific form, fit, and electrical characteristics needed for applications that require the Q2L3150H. It's a straightforward, built-to-last component for properly matched electrical distribution applications.

Material Compliance and Certifications

• Specific material compliance details and certification information were not provided with the available Q2L3150H specifications. Because markings and approvals can vary by the exact breaker and production version, it's better to verify these details on the product label or in the applicable documentation rather than assume a particular certification.
• Before installation, confirm that the breaker complies with applicable electrical codes, equipment specifications, and certification requirements for the job.

Where It Works Best

• The Q2L3150H makes the most sense when you're maintaining existing electrical equipment that was designed for this breaker type and rating. Typical applications may include compatible commercial, industrial, institutional, and facility electrical distribution equipment where maintaining the original breaker configuration is important.
