HMD63B600 - 600Amp Circuit Breaker

HMD63B600 - 600Amp Circuit Breaker

When you’re replacing a circuit breaker, the catalog number is only the starting point. The Siemens HMD63B600 is an MD-frame molded-case circuit breaker rated at 600 amps, 3-pole, and up to 600 VAC. It uses a thermal-magnetic trip unit and carries interrupting ratings of 50 kAIC at 600V and 65 kAIC at 480V. If your existing installation specifies the HMD63B600 and its corresponding MD-frame configuration, this breaker provides the intended form, fit, and function. It’s a substantial electrical component designed for the job and built to last.

Material Compliance and Certifications

The HMD63B600 molded-case circuit breaker meets the UL 489 and IEC 60947-2 standards. These standards are important when confirming whether a breaker meets the requirements of a particular electrical system or replacement application.

Manufacturer information also classifies the product as non-dangerous goods and lists its export classification as AL: N / ECCN: EAR99. WEEE take-back obligations are listed as “No.” RoHS compliance information and a SCIP number are not provided in the supplied manufacturer specifications.

Where It Works Best

The Siemens HMD63B600 is best suited to electrical equipment that specifically requires an MD-frame, 600A, 3-pole molded case circuit breaker with the corresponding voltage, interrupting capacity, trip characteristics, and connections.

It can be particularly useful in legacy equipment and existing electrical systems where maintaining the original breaker configuration is important. In these situations, matching the physical and electrical specifications helps preserve the intended form, fit, and function of the equipment.
