Siemens LGG3B030L - 30 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Siemens LGG3B030L is a dependable 30A, 600V, 3-pole molded case circuit breaker designed to safeguard your electrical system with precision. Built for branch circuit overcurrent and short-circuit protection, this unit integrates seamlessly into panelboards and loadcenters, delivering reliable performance where it matters most.

Key advantages

• Compact molded case design maximizes panel space and simplifies installation without compromising protection.
• Thermal-magnetic trip unit provides stable, repeatable protection against both sustained overcurrents and instantaneous short circuits.
• 3-pole configuration supports three-phase circuits, ideal for modern electrical systems.
• 600V rating ensures compatibility with a wide range of commercial and light industrial applications.
• OEM load center compatibility designed to pair with matching Siemens load centers and panelboards for a streamlined upgrade or replacement.

Why this matters for your electrical installations

In any panelboard or loadcenter, accurate protection is critical. The LGG3B030L’s thermal-magnetic trip mechanism reacts quickly to faults, reducing the risk of overheated conductors and damage to equipment. Its 30A rating is ideal for protecting branch circuits and feeders without unnecessary nuisance trips, while the 3-pole design supports balanced, three-phase systems common in commercial settings.

Ideal use cases

• Residential panels where a compact, reliable 3-pole breaker is required for multi-wire branch circuits.
• Commercial electrical rooms and light industrial spaces needing robust short-circuit protection for three-phase loads.
• Panelboard or loadcenter upgrades that require an OEM-compatible breaker with predictable, repeatable performance.
