Siemens LFX3G100 3-Pole Molded Case Circuit Breaker

The Siemens LFX3G100 is a three-pole molded‑case circuit breaker rated for 100 amperes and a maximum voltage of 600 volts, engineered to protect three‑phase circuits in distribution panels, switchboards, or industrial control enclosures where reliable interruption of fault currents is required. It uses LFGA 1-barrel lug terminals, providing secure, straightforward field connections and simplifying wiring in compact electrical spaces. The 3‑pole configuration protects three current paths in tandem, making it suitable for feeders and branch circuits on 3‑phase systems and enabling integration into typical Siemens panel builds. As part of the LFX3G100 family, this unit is a molded‑case breaker designed for use in commercial and light‑industrial panels, providing reliable overload and short‑circuit protection for circuits up to 600 V.
