HFD62B175 - 175Amp Circuit Breaker

HFD62B175 - 175Amp Circuit Breaker

When you’re replacing a circuit breaker in existing equipment, the details matter. The Siemens HFD62B175 is a 175A, 2-pole molded case circuit breaker in the FD frame, rated for applications up to 600VAC. It uses a thermal-magnetic trip unit for overload and short-circuit protection and carries an interrupting rating of 25 kAIC at 600V and 65 kAIC at 480V. The breaker comes with TA1FD350A load-side lugs, accepting copper wire from 6 AWG through 350 kcmil and aluminum wire from 4 AWG through 350 kcmil.

Key Features and Benefits

• 175A, 2-pole configuration for compatible commercial and industrial electrical equipment.
• 600VAC maximum voltage rating for applications calling for this FD-frame configuration.
• Thermal-magnetic trip protection responds to overload and short-circuit conditions.
• TA1FD350A load-side lugs are included with the breaker.
• Accepts 6 AWG to 350 kcmil copper conductors.
• Accepts 4 AWG to 350 kcmil aluminum conductors.
• FD-frame construction makes it easier to match the breaker to compatible existing equipment.
• Meets UL 489 and IEC 60947-2 standards.
