HLMD63B500L - 500Amp Circuit Breaker

HLMD63B500L - 500Amp Circuit Breaker

The Siemens HLMD63B500L is a SENTRON molded-case circuit breaker designed for your applications requiring a 500-amp, 3-pole, 600 VAC LMD-frame breaker with a thermal-magnetic trip unit. Rated 50 kAIC at 600V and 65 kAIC at 480V, this breaker is particularly useful when matching the electrical and physical requirements of compatible commercial and industrial equipment. For maintenance and replacement work, the catalog number, LMD frame, amperage, pole count, voltage, interrupting rating, trip type, lug configuration, conductor range, and dimensions should all be verified against the equipment requirements.

Key Features and Benefits

• 500A current rating – Designed for equipment and electrical systems specified for a 500-amp molded case circuit breaker.
• 3-pole configuration – Suitable for compatible three-phase electrical applications requiring three-pole circuit protection.
• 600 VAC rating – Matches applications designed around the breaker's specified 600 VAC maximum voltage rating.
• Thermal-magnetic trip unit – Combines thermal and magnetic tripping functions for overcurrent protection.
• LMD frame – Helps simplify identification when matching a breaker to compatible LMD-frame equipment.
• Line and load lugs included – Equipped with TA3K500 lugs on both sides of the breaker.
• Flexible conductor compatibility – Accepts 1/0 AWG to 500 kcmil copper or aluminum conductors.

Material Compliance and Certifications

The Siemens HLMD63B500L meets UL 489 and IEC 60947-2 standards. These certifications are especially relevant when confirming whether a replacement circuit breaker satisfies the requirements established for a particular piece of equipment or electrical installation.

Manufacturer data also identifies REACH Article 33 information for this product. RoHS substance-restriction compliance information and a SCIP number are listed as unavailable in the supplied manufacturer specifications, so those compliance attributes should not be assumed.

Where It Works Best

The HLMD63B500L is best suited to commercial and industrial electrical applications that specifically require a 500A, 3-pole LMD-frame molded-case circuit breaker rated for 600 VAC. It can be especially relevant for maintenance and form, fit, and functional replacement in compatible existing or legacy electrical systems where the original equipment specifications correspond to this Siemens configuration.
