HFD62B080L - 80Amp Circuit Breaker

HFD62B080L - 80Amp Circuit Breaker

When your existing electrical system calls for a Siemens HFD62B080L, the safest way to approach replacement is to match the breaker by its complete set of specifications—not amperage alone. The HFD62B080L is an 80 Amp, 2-pole Sentron molded case circuit breaker built around the FD/HFD6 frame for compatible commercial and industrial equipment. It uses a thermal-magnetic trip unit, is based on a standard 40°C breaker configuration, and is rated for applications up to 600VAC.

Material Compliance and Certifications

The HFD62B080L configuration is specified around UL 489 and IEC 60947-2 requirements, important reference points when evaluating a molded case circuit breaker for compatible electrical equipment. These standards should be considered alongside the breaker's amperage, voltage, frame, pole count, trip characteristics, and interrupting capacity.

Where It Works Best

The Siemens HFD62B080L 80A circuit breaker is a good fit for commercial and industrial electrical equipment designed around a 2-pole FD/HFD6 molded case breaker with matching electrical and mechanical specifications. It is especially relevant to maintenance and replacement work involving existing or legacy systems where changing the breaker style isn't the objective—the goal is to maintain the required form, fit, ratings, terminals, and function.
