HFD63B080L - 80Amp Circuit Breaker

HFD63B080L - 80Amp Circuit Breaker

When your existing electrical system calls for a specific breaker, the small details matter. The Siemens HFD63B080L is an 80A, 3-pole molded case circuit breaker in the SENTRON HFD6 family, designed around the FD frame and rated for applications up to 600VAC. It uses a thermal-magnetic trip unit and carries interrupting ratings of 25 kAIC at 600V and 65 kAIC at 480V.

Key Features and Benefits

• 80A, 3-pole design matches applications calling for this specific current rating and pole configuration.
• 600VAC rating supports compatible FD-frame electrical systems.
• Thermal-magnetic trip unit provides overload and short-circuit protection.
• Comes assembled with TA1FD350A line- and load-side lugs.
• Handles a broad conductor range: 6 AWG–350 kcmil copper and 4 AWG–350 kcmil aluminum.
• 4.5 x 9.5 x 4-inch dimensions make it easier to confirm physical compatibility before installation.
