HFD62B070L - 70Amp Circuit Breaker

HFD62B070L - 70Amp Circuit Breaker

When you’re replacing a circuit breaker in an existing electrical system, getting the details right matters. The Siemens HFD62B070L is a 70-amp, 2-pole HFD6 Sentron-frame molded case circuit breaker designed for compatible commercial and industrial equipment. It operates at 50/60 Hz and is rated at 40°C, with interrupting capacities of 25 kA at 600VAC, 65 kA at 480VAC, and 100 kA at 240VAC. This model uses an interchangeable trip unit and comes with both line- and load-side terminals, important details when you're trying to match the configuration of an existing breaker rather than simply finding another 70A unit.

Key Features and Benefits

• 70A, 2-pole design – Matches applications requiring this specific amperage and pole configuration.
• HFD6 Sentron frame – Designed for equipment that uses the HFD6 molded case breaker format.
• Rated up to 600VAC – Suitable for compatible commercial and industrial AC systems.
• Interchangeable trip unit – Maintains the trip-unit configuration associated with this HFD6 breaker.
• Terminals included – Supplied with both line- and load-side terminals.
• HACR rated – Appropriate for compatible heating, air-conditioning, and refrigeration applications.
• 50/60 Hz operation – Designed for commonly used AC power frequencies.

Material Compliance and Certifications

The HFD62B070L is HACR rated, making it suitable for compatible heating, air-conditioning, and refrigeration equipment when the installation calls for its specific electrical ratings and configuration.

Where It Works Best

The Siemens HFD62B070L makes the most sense in commercial and industrial systems already designed around a 70A, 2-pole HFD6 Sentron-frame circuit breaker. That includes maintenance and replacement situations where keeping the original breaker footprint, electrical characteristics, terminal arrangement, and trip configuration is important. Its HACR rating also supports use in compatible HVAC and refrigeration applications.
