HFD62B150L - 150Amp Circuit Breaker

HFD62B150L - 150Amp Circuit Breaker

When you’re replacing a circuit breaker in existing equipment, getting the details right matters. The Siemens HFD62B150L is a 150A, 2-pole molded case circuit breaker built on the FD frame and designed for electrical systems rated up to 600VAC. It uses a thermal-magnetic trip unit and carries an interrupting rating of 25 kAIC at 600V and 65 kAIC at 480V. For maintenance and replacement work, those specifications—along with the frame size, pole configuration, dimensions, and connection requirements—make it easier to determine whether this breaker matches the existing application.

Material Compliance and Certifications

The HFD6 family information supplied for this breaker identifies compliance with UL 489 and IEC 60947-2. These standards are useful reference points when checking whether a molded case circuit breaker meets the requirements of a particular electrical installation.

Where It Works Best

The HFD62B150L makes the most sense in commercial and industrial electrical distribution systems that call for a 150A, 2-pole FD-frame circuit breaker rated up to 600VAC. It's particularly relevant when maintaining existing or legacy equipment and the goal is to replace a breaker while keeping the required electrical ratings and physical configuration intact.
