HFD62B110 - 110Amp Circuit Breaker

HFD62B110 - 110Amp Circuit Breaker

When you need to match an existing Siemens FD-frame breaker, the details matter. The HFD62B110 is a 110-amp, 2-pole Sentron molded case circuit breaker with a thermal-magnetic trip unit and a maximum rating of 600VAC. It is rated at 25 kAIC at 600V and 65 kAIC at 480V, making those ratings important checkpoints when confirming it for an existing installation. The breaker comes with TA1FD350A load-side lugs, which accept 6 AWG through 350 kcmil copper wire or 4 AWG through 350 kcmil aluminum wire.

Key Features and Benefits

• 110A, 2-pole design for equipment requiring this specific electrical configuration.
• FD frame construction helps maintain the required physical fit in compatible installations.
• Handles applications rated up to 600VAC.
• Thermal-magnetic trip unit provides the breaker's specified overload and short-circuit protection.
• Includes TA1FD350A load-side lugs.
• Accommodates 6 AWG–350 kcmil copper and 4 AWG–350 kcmil aluminum conductors.
• Standard 40°C breaker configuration.

Material Compliance and Certifications

The HFD62B110 meets UL 489 and IEC 60947-2 standards for circuit breakers. Manufacturer data lists RoHS substance-restriction compliance information as not available and does not provide a SCIP number. REACH Article 33 information is maintained separately by the manufacturer. For projects with specific compliance requirements, these details should be confirmed against the documentation required for the installation.

Where It Works Best

The HFD62B110 makes the most sense in commercial and industrial electrical systems already designed around a Siemens FD-frame, 110A, 2-pole molded case circuit breaker with the appropriate voltage and interrupting ratings. It's particularly relevant for maintenance and replacement situations where keeping the specified form, fit, and function matters.
