Siemens LXD63B600 - 600 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens LXD63B600 is a 3-pole, 600A, 480V molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built to endure through vibration and equipment movement, its bolt-on design delivers a secure, rigid bus connection that stays put where it matters most.

Key to its reliability is a thermal-magnetic trip unit that provides stable, repeatable protection. The thermal element handles gradual heating from overcurrent, while the magnetic element clamps down quickly on short circuits, helping to minimize nuisance trips and protect both equipment and occupants.

Designed for seamless integration, this unit is compatible with matching OEM Siemens load centers and panelboards, ensuring proper fit, coordination, and performance within your 480V electrical system.

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection.
• Thermal-magnetic trip unit delivering stable, repeatable protection.
• Compatibility with matching Siemens OEM load centers and panelboards.
• Versatility suitable for residential, commercial, and light industrial applications needing robust 3-phase protection at 480V.
