• Three‑pole configuration provides synchronized protection for three‑phase circuits, helping prevent phase imbalances and equipment damage.
• 80A, 600V rating targets common branch circuits and motor loads found in offices, retail spaces, and light industrial settings, while handling higher voltage systems safely.
• OEM panel compatibility designed to pair with matching Siemens OEM load centers and panelboards, ensuring straightforward replacement and streamlined upgrades.

How this breaker protects your system

At the heart of the LGG3B080L is a thermal element that reacts to gradual overloads and a magnetic element that trips instantly on short circuits. This combination limits heat buildup, minimizes wear on conductors, and prevents cascading failures across your distribution network. With precise trip characteristics and no need for field adjustments, it’s a reliable guardian for everyday equipment and critical loads alike.

Ideal use cases

• Residential panel upgrades or replacements in homes with three‑phase equipment requirements.
• Commercial service panels in offices, retail storefronts, or data centers where space is at a premium and dependable protection is essential.
• Light industrial distribution where three‑phase motors, conveyors, or processing equipment demand robust overcurrent and short‑circuit protection.
• Spare or replacement breaker in Siemens‑equipped panelboards to maintain system compatibility and reduce downtime during service work.

Compatibility and installation considerations

The LGG3B080L is designed to be paired with matching Siemens OEM load centers and panelboards, ensuring coordinated protection and straightforward replacement within existing electrical infrastructure. Its 3‑pole design is well suited for three‑phase distribution, and the 80A rating makes it a practical choice for common branch circuits and motor loads. When installing, follow standard electrical practices for molded‑case breakers, including proper seating, secure lugs, and adherence to local electrical codes.
