HFD62B110L - 110Amp Circuit Breaker

HFD62B110L - 110Amp Circuit Breaker

When an existing electrical system calls for a Siemens HFD62B110L, getting the specifications right matters. This 110-amp, 2-pole molded case circuit breaker is part of the Siemens FD-frame family and uses a thermal-magnetic trip unit for overload and short-circuit protection. Rather than treating breakers with similar amperage as interchangeable, check the complete set of ratings and installation requirements against the equipment you're servicing. With the right application and proper installation, this is a straightforward, built-to-last solution for maintaining the intended form, fit, and function of compatible electrical equipment.

Key Features and Benefits

• 110-amp rating for equipment designed around this specific current requirement.
• 2-pole configuration for compatible two-pole applications.

Material Compliance and Certifications

The HFD62B110L molded case circuit breaker is specified to meet UL 489 and IEC 60947-2, two recognized standards applicable to low-voltage circuit breakers.

Where It Works Best

The Siemens HFD62B110L fits best in commercial and industrial electrical applications that specifically call for a 110A, 2-pole FD-frame molded case circuit breaker with the corresponding voltage and interrupting ratings. It can also make sense for maintenance of existing and legacy electrical equipment where keeping the original breaker configuration is important.
