Product description
Shipping

The Siemens LL63B500 is a rugged 500 A, 3-pole circuit breaker designed for reliable protection in three-phase power distributions up to 600 V. Built to withstand demanding industrial and commercial environments, this LL63B500 model preserves system integrity by interrupting all three phases simultaneously when faults occur.

Key specifications

  • Part Number: LL63B500
  • Current rating: 500 A
  • Poles: 3
  • Voltage rating: 600 V

Why this matters

In three-phase electrical systems, a coordinated trip across all phases is essential to prevent phase imbalance and potential damage to motors, drives, and downstream equipment. The LL63B500 delivers reliable, synchronized interruption, helping to protect feeders, transformers, and heavy loads from overloads and short circuits. With a 600 V rating, it is suitable for a wide range of commercial and industrial applications where robust, dependable protection is critical.

Use cases and ideal environments

  • Industrial motor control centers and distribution panels with high-current three-phase loads
  • Commercial facilities that rely on stable three-phase power for equipment, conveyors, and HVAC systems
  • Data centers or server rooms with three-phase power distribution requiring reliable fault isolation
  • Factory floors and manufacturing lines where rapid, coordinated interruption protects both people and equipment

Practical considerations

When selecting protection for three-phase circuits up to 500 A, the LL63B500 pairs well with Siemens panel ecosystems designed to accommodate LL63-type breakers. Ensure correct panel compatibility and follow all local electrical codes during installation. For maintenance and longevity, rely on standard electrical practices, including periodic inspection of terminations and verification of proper torque on connections.

What you gain

  • Reliable 3-pole protection for high-current, three-phase systems
  • Clear protection up to 600 V, enabling safe interruption of faults on diverse installations
  • Specific model clarity with part number LL63B500 for straightforward sourcing and replacement
