HFD63B100L - 100Amp Circuit Breaker

HFD63B100L - 100Amp Circuit Breaker

The Siemens HFD63B100L is a 100A, 3-pole molded case circuit breaker designed for compatible SENTRON electrical equipment that uses the FD frame. It is rated up to 600VAC and uses a thermal-magnetic trip unit for your overload and short-circuit protection. The breaker is rated 25 kAIC at 600V and 65 kAIC at 480V, so those values should be compared with the requirements of the existing electrical system before installation.

Material Compliance and Certifications

The Siemens HFD63B100L circuit breaker meets UL 489 and IEC 60947-2 standards. These certifications provide useful reference points when confirming that the breaker matches the requirements of the electrical equipment where it will be installed. For electrical components, accurate specifications matter. Clear details about ratings, connections, and compatibility help customers identify the correct part without relying on assumptions based only on amperage.

Where It Works Best

The Siemens HFD63B100L is a good fit for commercial and industrial electrical distribution equipment that specifically requires a 100A, 3-pole FD-frame molded case circuit breaker. It is especially relevant for maintenance and replacement work where the goal is to keep the original equipment configuration intact.
