HFD62B080 - 80Amp Circuit Breaker

HFD62B080 - 80Amp Circuit Breaker

The Siemens HFD62B080 is an 80-amp, 2-pole Sentron molded case circuit breaker built around the FD/HFD6 frame for compatible commercial and industrial electrical systems. Designed for applications up to 600VAC, this breaker uses a thermal-magnetic trip unit and carries an interrupting rating of 25 kAIC at 600VAC and 65 kAIC at 480VAC. When your application specifically calls for an HFD62B080 or a breaker with matching form, fit, electrical ratings, and functional requirements, this Siemens circuit breaker provides the configuration needed to keep compatible equipment in service. Simply put, it's made for a specific electrical job and built to last when properly selected, installed, and operated within its stated ratings.

Material Compliance and Certifications

The Siemens HFD62B080 is specified by the manufacturer as meeting UL 489 and IEC 60947-2 standards for molded case circuit breakers. These standards are relevant when confirming whether the breaker satisfies the requirements of a particular electrical installation or piece of equipment.

Where It Works Best

The HFD62B080 is best suited to commercial and industrial electrical equipment designed for an 80A, 2-pole Siemens FD/HFD6 frame molded case circuit breaker with the corresponding voltage, interrupting ratings, lug arrangement, and physical footprint. It can be particularly useful when maintaining existing or legacy equipment where form, fit, and function need to remain consistent with the original system design.
