Leviton LM100-T Main Circuit Breaker 100A, Thermal Magnetic

Protect your facility’s power backbone with the Leviton LM100-T main circuit breaker — a dependable 100A, 2-pole thermal-magnetic solution designed for commercial and residential load centers. The LM100-T delivers precise overload and short-circuit protection at 120/240V and a 22kA interrupt rating, minimizing risk to sensitive equipment used in security, surveillance, monitoring and network applications. Because it’s engineered specifically for Leviton load centers, the LM100-T installs quickly and pairs with standard 225A bussing for flexible project scaling without replacing the panel. That reliability reduces downtime for critical systems like CCTV recorders, access control panels and IT racks. Finished to match Leviton indoor load centers, it provides a clean, professional look while offering long-term assurance backed by a 10-year limited warranty. Choose the LM100-T to ensure consistent, code-compliant protection for your electrical distribution and low-voltage infrastructure. Order now or contact our sales team for bulk and project pricing.
