HFD63B150L - 150Amp Circuit Breaker

HFD63B150L - 150Amp Circuit Breaker

When you’re replacing a breaker in existing equipment, the details matter. The Siemens HFD63B150L is a 150-amp, 3-pole molded case circuit breaker from the SENTRON FD-frame family, designed for applications up to 600VAC. It uses a thermal-magnetic trip unit to provide overload and short-circuit protection and is rated at 25 kAIC at 600V and 65 kAIC at 480V.

Key Features and Benefits

• 150A, 3-pole design for compatible three-phase electrical systems.
• 600VAC maximum voltage rating for applications requiring this specific FD-frame configuration.
• Thermal-magnetic trip unit handles overload and short-circuit protection without unnecessary complexity.
• TA1FD350A line and load lugs are included as part of the breaker configuration.
• Works with a broad conductor range: 6 AWG–350 kcmil copper and 4 AWG–350 kcmil aluminum.
• FD-frame dimensions make it suitable for replacement applications where matching the existing footprint is important.
• Built to last when properly installed and operated within its specified electrical ratings.
