HFD62B070 - 70Amp Circuit Breaker

HFD62B070 - 70Amp Circuit Breaker

When you need a Siemens HFD62B070, getting the details right matters. This 70A, 2-pole FD-frame molded case circuit breaker uses a thermal-magnetic trip unit and is rated for operation up to 600 VAC. Its interrupting capacity is 25 kAIC at 600V and 65 kAIC at 480V. The breaker comes equipped with TA1FD350A lugs on the load side, with a conductor range of 6 AWG through 350 kcmil for copper and 4 AWG through 350 kcmil for aluminum.

Key Features and Benefits

• 70 Amp, 2-pole design for equipment requiring this specific FD-frame configuration.
• 600 VAC rating supports compatible commercial and industrial electrical applications.
• Thermal-magnetic trip unit provides the breaker's specified overcurrent protection.
• Standard 40°C breaker design.

Material Compliance and Certifications

The Siemens HFD62B070 circuit breaker meets UL 489 and IEC 60947-2 standards, an important consideration when matching a breaker to equipment with defined certification or compliance requirements. For this catalog number, manufacturer data does not provide an available RoHS substance-restriction status or SCIP number. If your project has specific material or environmental compliance requirements, confirm those requirements separately rather than assuming compliance.

Where It Works Best

The HFD62B070 makes the most sense in commercial or industrial low-voltage electrical systems designed for a 70A, 2-pole FD-frame breaker with the ratings listed above. It's particularly relevant for maintenance and replacement work involving existing or legacy electrical equipment where keeping the correct form, fit, and electrical function is the priority.
