HFD62B150 - 150Amp Circuit Breaker

HFD62B150 - 150Amp Circuit Breaker

When your electrical system calls for a Siemens HFD62B150, getting the details right matters. This 150A, 2-pole molded case circuit breaker is part of the Siemens HFD6 family and uses an FD frame with a thermal-magnetic trip unit. It is rated for applications up to 600VAC, with an interrupting rating of 25 kAIC at 600V and 65 kAIC at 480V.

Key Features and Benefits

• 150-amp, 2-pole configuration for equipment designed around these specific electrical requirements.
• Rated up to 600VAC, providing the required voltage rating for compatible applications.
• Thermal-magnetic trip unit provides overload and short-circuit protection.
• FD frame design makes physical frame compatibility easier to verify when replacing an existing breaker.
• Supplied with TA1FD350A load-side lugs.
• Accepts a broad conductor range: 6 AWG to 350 kcmil copper and 4 AWG to 350 kcmil aluminum.
• Meets UL 489 and IEC 60947-2 standards.

Material Compliance and Certifications

The HFD62B150 meets UL 489 and IEC 60947-2 standards. These are important reference points when confirming whether the breaker meets the requirements of a particular electrical system or project.

Where It Works Best

The Siemens HFD62B150 makes the most sense where the existing electrical equipment specifically calls for a 150A, 2-pole FD-frame molded case circuit breaker with matching voltage, interrupting, trip, lug, and dimensional requirements. That can include maintenance and replacement work involving compatible commercial or industrial electrical distribution equipment, particularly existing or legacy installations where maintaining the correct form, fit, and function is the priority.
