HLMD63B600 - 600Amp Circuit Breaker

HLMD63B600 - 600Amp Circuit Breaker

The Siemens HLMD63B600 is a 600A, 3-pole molded-case circuit breaker from the SENTRON LMD-frame family, designed for use in compatible low-voltage commercial and industrial electrical systems. It uses a thermal-magnetic trip unit and carries a 600 VAC voltage rating, with an interrupting capacity of 50 kAIC at 600V and 65 kAIC at 480V. Whether you're maintaining existing equipment or replacing a breaker with matching requirements, the HLMD63B600 circuit breaker is built to last. It provides the specific form, fit, ratings, and functionality required by compatible systems.

Key Features and Benefits

• 600A current rating: Designed for electrical equipment requiring a 600-amp molded case circuit breaker.
• 3-pole configuration: Intended for compatible three-phase applications requiring three-pole circuit protection.
• 600 VAC rating: Suitable for systems designed around the breaker's specified maximum voltage rating.
• Thermal-magnetic trip unit: Provides thermal and magnetic tripping functions for overcurrent protection.
• LMD frame construction: Makes it easier to identify the correct frame configuration when matching an existing breaker or compatible equipment.
• TA3K500 load-side lugs: Supplied with load-side lugs designed for the specified conductor range.
• Copper and aluminum conductor compatibility: Accommodates 1/0 AWG through 500 kcmil Cu/Al conductors.
