HMD63B800 - 800Amp Circuit Breaker

HMD63B800 - 800Amp Circuit Breaker

When your existing electrical system calls for a Siemens HMD63B800, getting the details right matters. This SENTRON molded case circuit breaker is an 800A, 3-pole MD-frame breaker rated for applications up to 600VAC. It uses a thermal-magnetic trip unit and carries interrupting ratings of 50 kAIC at 600V and 65 kAIC at 480V. The HMD63B800 also comes with TA3K500 load-side lugs that accept copper or aluminum conductors from 1/0 AWG through 500 kcmil.

Key Features and Benefits

• 800A, 3-pole design for systems requiring this specific configuration.

Material Compliance and Certifications

The HMD63B800 circuit breaker meets UL 489 and IEC 60947-2 standards. These standards are useful when checking whether the breaker meets the requirements of an existing electrical installation.

Manufacturer information also lists the product under ECCN EAR99 and identifies it as non-dangerous goods. WEEE (2012/19/EU) take-back obligations are listed as No. REACH Article 33 information is available from the manufacturer, while RoHS substance-restriction compliance and a SCIP number are listed as not available.

Where It Works Best

The Siemens HMD63B800 is suited to existing electrical distribution equipment designed around an 800A, 3-pole MD-frame molded case circuit breaker. It's especially relevant when the job calls for maintaining the correct form, fit, and function rather than changing the electrical system's original configuration.
